Wi-Fi does not work on a laptop: causes and ways to eliminate the problem

Causes that can cause the unavailability of Wi-Fi wireless network on a laptop are different. Comfortable problems are usually eliminated in workshops. However, many malfunctions to correct any user at home.

The reason is the laptop or router?

If the laptop does not connect to the Wi-Fi network, you need to determine in which of the devices the source of the problem is in the portable computer or in the router producing the distribution of the wireless Internet.

To check, you need to try to connect to the wireless network from another computer or mobile device. If the verification shows that Wi-Fi does not function from other gadgets, then the reason must be sought in a Wi-Fi router. With a successful connection, you can not doubt that the source of the problem is in a laptop.

Initial actions

Simple, but a fairly effective way, - reboot and laptop, and router. Rebooting, the router before the start of the distribution of the network is not included instantly, but within 5-10 minutes.

You can also use the standard optional diagnostic option available in Windows.

If these elementary methods did not help, it should be proceeded to more detailed diagnostics and eliminating problems identified.

Checking hardware adapter enable

If the problem is in a laptop, you need to start gradually identify the reason that caused the inoperability of Wi-Fi. You should start with checking the adapter on the device:

  1. Check if the wireless adapter is enabled. On modern models there is a light indicator - when the module is turned on, it should burn green, otherwise (it does not burn at all or on red) it must be turned on. In most cases, the indicators are installed on the laptop enclosure panel (less often in the neighborhood with a touchpad or on the monitor housing).
  2. Click to turn on the network module, the Fn key combination and the system F with the corresponding icon in the form of antenna. In the absence of such an icon, press the typical combination of Fn + key for a specific laptop brand: F2 - ASUS; F3 - Acer; F5 - Fujitsu, Lenovo; F9 - SAMSUNG; F12 - HP, Dell.
  3. Checking, the module is turned on or not. If you successfully solve the problem, the indicator begins to glow or the red indicator is replaced by green.
  4. We make a new attempt to connect to a wireless network.

Hardware Turning Problem

If the Wi-Fi does not start as a result of a hardware power failure, you need to produce software directly from the operating system. To implement this process, adhere to the following algorithm of action:

  • Windows 7 and 8: Start (for Windows 8 Keyboard Win + X key) - Control Panel - Network and Internet Network Management Center and Shared Access - Changing the Adapter Parameters (left on the panel)
  • Windows 10: Keyboard Win + X keys - Network connections - Network Management Center ... and then by analogy above.

Near the "Wireless Network Connection" icons ("Wireless Network") when the adapter is turned off and the Wi-Fi functioning icon, as a rule, is not highlighted (i.e. it remains gray).

Enable wireless network

Click on the right mouse button icon. When the list opens, you need to select "Enable". If the procedure is properly observed, the wireless adapter turns on, the connection icon varies in color.

After that we are looking for in the list of available wireless networks you need and connect to it.

Connect to wireless network

Missing (or outdated) drivers

Quite often, the laptop happens next: Wi-Fi is on, but the device does not detect the network. More than 70% of cases cause no detection or non-network connection is the lack of necessary drivers.

Often this happens after reinstalling the operating system, as a result of which various problems may occur: the adapter will be badly operating or a wireless device will be physically located in the system, and Windows will not know about it.

To determine the presence of the driver you need to make a number of actions:

  1. Go to the Device Manager. This is done: right-click on the "Computer" icon on the desktop, select "Management" and select "Device Manager" in the left column.
  2. Locate the "Network Adapters" string, and in the deployed list of connected devices, select a string with a wireless network adapter (or Wireless). Nearby should be the name of the manufacturer of the network card. Properties of a network adapter
  3. Finding what you need, right-click and select "Properties". There must be a message that this device works fine. However, such information can not serve as a guarantee that the required driver and Wi-Fi is installed on the computer.
  4. Click the Driver tab. Here it will be necessary to check its data, paying special attention to the supplier and the year of the driver. If the supplier is Microsoft, it will be necessary to open the official website of the laptop manufacturer and download the modern version of the driver. Similar actions are performed and in the case when the wireless adapter is missing in the list of installed devices or the program is outdated for several years. Properties of a network adapter

Download drivers only from the official site of the manufacturer. This will serve as a guarantee from the emergence of trouble with the launch of Wi-Fi.

If in the list of devices, the Wi-Fi module is detected, but it is worth a yellow exclamation mark that reports that the device is not turned on, open the device properties window and activate the "Enable" function (or "Enable the device").

Diet

Another reason, due to which Wi-Fi may not work - incorrectly installed energy consumption mode, resulting in problems with a wireless connection. To transfer to the appropriate mode, the following operations must be done alternately (for Windows 7):

  1. Open the control panel.
  2. Select a position with the "Power" icon.
  3. Expose in the window that opens instead of economical - high productivity of the power supply.

In Windows 10 other action algorithm:

  1. Click "Start", then on the left to the gear ("Parameters").
  2. Go to the "system" and choose in the column on the left "Power and sleep mode".
  3. Find the "Related Parameters" title and under it click on "Advanced Power Parameters".
  4. Clause on the "Settings of the Power Scheme" link and select High Performance.

Power supply. High performance laptop

External obstacles

Wi-Fi may not work not only because of problems with a laptop. There are a large number of external factors capable of making a weak wireless connection. As such obstacles, floors, walls, ceilings, as well as other similar obstacles can be.

You can track the signal level on the portable computer by special marks on the quality scale of the network - the more they are shown, the better the signal. With a low level (1-2), it is unlikely that it makes sense to count on the stable Wi-Fi operation.

You can try to adjust this indicator, transferring a router or moving the workplace. Experienced users in this situation are advised to acquire a more powerful device.

We also recommend reading the article called "How to Strengthen Routher Signal".

Other reasons

The problems described above with the wireless adapter are most common and, as a rule, are eliminated by their own. However, more serious problems can be facilitated by the poor quality of the wireless module:

  • Wi-Fi Module Malfunction . If you cannot fix the problem with reinstalling the driver (in this case, the signal is present), then the reason will most likely lift in errors that have arisen as a result of damage to the board itself. There is no laptop without disassembling a laptop. To do this, you need to have a certain experience, and if it is not, then the best way out of the situation will appeal to the workshop. The complexity of the repair will depend on whether the element is integrated with the motherboard or not. If the laptop is constructively connected to the module on the PCI slot, it is possible to replace the replacement quickly and without special costs. In the event that it is difficult to find a similar transmitter or not the desire to disassemble, there is a simpler output - buy an external USB adapter for Wi-Fi or more advanced (respectively, more expensive) ExpressCard.
  • The antenna wire is not connected. . Pretty common physical damage. Most often it takes place in laptops who visited the workshop, or after cleaning from the dust of the cooling system by the owner. Nobody remembers an antenna, so the adapter has a problem with the connection even close to the signal source. To eliminate it, connect the antenna to the wireless network module.
  • Wireless router . The reason for the lack of connecting the Wi-Fi network on a laptop can be the simplicity of incorrect configurations (for example, the address blacklist, which includes a laptop, encryption, SSID broadcast mode).
  • Viruses . Malicious software can disrupt the wireless network settings. The laptop should be cleaned from viruses, using the antivirus program. For Windows operating system, Microsoft specially developed a basic free MSE anti-virus application (Microsoft Security Essentials). You need to install it on a laptop to protect.
  • Overheating network card . It occurs when the laptop is installed on the surface that does not correspond to the rules of operation of the device (for example, on a sofa, knees, etc.). As a result, the holes are overlapped at the bottom of the laptop housing, intended for the penetration of cold air on the fees. So it happens when the cooling system is clogged with dust. Overheating leads to breakage of some components. To prevent the laptop overheating, it is recommended to clean it from dust at least once a year. This will avoid the repair of the device and unwanted consequences as a result of its overheating.
  • Burned wireless adapter . In this case, you have to replace it with a new device. Such a breakdown will be determined by the device manager - it will not display the module. An attempt to install drivers for Wi-Fi will throw out a message about the absence of this device in the system.

Described in the methods of solving problems associated with the work of Wi-Fi on a laptop, any particular difficulty and harm can use any user. If nothing helped and the wireless network did not work, you need to contact the service center, where you will definitely help to establish Wi-Fi on Laptop.

Noutbuk-ne-Podklyuchaetsya-K-WiFiGood day!

Perhaps most issues on laptops that I get are related to setting up Wi-Fi network (More precisely, why Wi-Fi does not work ☝) .

This may occur for various reasons, most often associated with installing new equipment, reinstalling Windows OS, a change in some settings, etc.

In this article, I want to touch on all the most basic reasons because of which the laptop may not connect and not see the Wi-Fi network.

Before inviting wizards to eliminate the problem (and spend funds) I believe that it is worth at least try to figure it out on your own - run through the problems below, diagnose the cause, and eliminate it ... 👌

*

Causes due to which the laptop does not connect to Wi-Fi

First aid: where to start

Windows troubleshooting diagnostics

First of all, when problems with the network, I want to recommend you to spend Diagnostic built in windows (This applies to those who work in a modern Windows 8, 8.1, 10) .

The diagnostic wizard is "smart" enough, and many program errors and failures eliminate automatic mode. I will give below a couple of ways as you can Run This Diagnostic ... 👌

Option 1

Just right-click on the network icon - znachok-seti-win10and then choose in the context menu "Troubleshooting" . Next, follow the instructions of the wizard.

After that it starts Master diagnostic which will independently recover settings and parameters, correct errors, restart the wireless adapter.

In many cases, such a simple procedure allows you to quickly restore the operation of the network and save you a bunch of time!

Diagnostics completed successfully

Diagnostics completed successfully: the problem with the wireless network adapter or the access point is fixed!

Restarting a computer and router

The second, I recommend to do is to restart the router and a laptop (computer).

The fact is that in many cases there are different kinds of errors and the connection on Wi-Fi is rushing, and the router does not restore it (although, in theory, I should ...) .

Such, for example, maybe if the light blinks, the Internet will disappear from the provider, the router will reboot in view of high load (note : Many Chinese inexpensive models are tugged at high download speed - if you limit it, it works as expected, the connection is stable and constant) .

In general, such a simple procedure, as a reboot - helps to fix it.

Does Wi-Fi work adapter on a laptop

The fact is that the Wi-Fi adapter (receiver on a laptop) may be good but Disabled .

On many models of laptops there is even a special LED that signals the operation of a wireless adapter - if everything is in order with it, the LED should burn!

LED on the laptop housing

In different models of laptops Wi-Fi adapter turns on differently:

  1. The most common option is the use of function keys, for example Fn + F2. (as in the photo below) . The key combination depends on the device model - look for the one that shows a wireless network (You can also look in the documentation for the device ☝) ;
  2. On some laptops there is a special switch on Wi-Fi (for example, on a number of devices from Lenovo, it is located on the side or above the keyboard, next to the power button / switch on the laptop) ;
  3. Sometimes it may not be any keys on the keyboard nor on the case of the device. Then include the adapter you need through Windows capabilities (about it below).

Are there drivers? Check and update

When installing Windows drivers for Wi-Fi is not always installed. (Of course, Windows 10 supports quite a lot of equipment, but not everything, especially since talking about Windows 7 ...) .

To check if you have a Wi-Fi adapter driver, go to the Device Manager and expand the tab. "Network adapters" и "Other devices" .

The screen below shows that there are no network adapters "Wireless Network Adapter" either "Wireless adapter ..." , and in the tab "Other devices" There is a device with an exclamation mark. There is a problem - no Wi-Fi adapter driver.

Wi-Fi stopped working on a laptop - decide

Wi-Fi does not work on a laptop what is the reason?

Causes of lack of opportunity to connect to Wi-Fi can be very different, conventionally can be divided into simple and complex. And in this article we will try to consider the main of them.

Banal (simple) causes of not working wai fi

  1. You have not paid the Internet - pay it.
  2. The router is not included - turn it on.
  3. No Wi-Fi coverage - go closer to the router.
  4. Your Router "Buggy" - reboot it.

Serious causes of not working Wi-Fi WiFi does not work on a laptopIf you have a problem with connecting to Wi-Fi, then first you need to determine what cause is: in the router or in a laptop.

The easiest way to know what is the problem, is to connect another device to your router or connect your laptop to another Wi-Fi network.

Not configured Wi-Fi router / router

Before connecting to a wireless network, you need to configure the router. If you have not done this, then you should find the instructions for the router of your model on the Internet for both of your provider.

To find out if the connection from the provider works, you need to check the admin panel or indicator on the WAN in the WANV. If the connection from the provider does not work, then the problem may be as follows:

  • The admin panel contains incorrect settings for connecting to the provider.
  • Router is faulty.
  • Problems from the provider. To exclude or confirm this option, you can contact the provider.

Wi-Fi does not work on a laptop - the receiver is not working (burned)

Sometimes the Wi-Fi laptop simply stops working. Connection to the network or absent, or it is unstable. The cause can be a breakdown of the Wi-Fi module in a laptop. Then it may be necessary to replace it or repair.

Not installed driver for a network card

Not installed driver for a network card

The most likely reason that the Internet does not connect on the laptop after reinstalling the operating system, is the inability of your new operating system to find and install the driver suitable for your network card.

As a rule, to install the driver on the network adapter, you must use the drivers with drivers that are included with the laptop, and you can also download the desired driver from the manufacturer's website for a specific model of your device.

Check for the driver installed on the network adapter in the device manager.

Wi-Fi module is not included in your laptop

There are 2 ways to enable Wi-Fi adapter programmatically if earlier it was disabled in OS settings:

1. Through the Center for Network Management and Common Access. You need to enter the NCPA.CPL command in the input window after pressing the Win + R combination. This command will open "Changing the Adapter Settings", from there you need to go to "Wireless Network Connection". If the grid adapter icon, then you need to turn it on. 2. Through the Device Manager. If the adapter is disabled in the device manager, the Wireless Network Connection icon will be missing in network connections. Then, as in paragraph 1, you need to press Win + R. Then you need to enter the DevmGMT.msc command, it will open the device manager. Next, we find a device that contains Wi-Fi or Wireless in its name, and after clicking the right mouse button you need to click "Enable". If the adapter does not turn on, then you need to check if there are suitable drivers.

Firewall or Antivirus block Internet access

Sometimes to interfere with your laptop to connect to Wi-Fi can protect your OS: antivirus or firewall.

If it's about the firewall, it is easy to solve the problem: it is just necessary to disable it in the system settings. If the obstacles are satisfied with the antivirus, then it is necessary to complete the necessary processes via the task manager, or you can turn off the antivirus itself.

Viruses and malicious programs block Wi-Fi

If you do not have an antivirus or it is outdated, then the likelihood you will come up with a virus-blocker. Such viruses block your Internet access allegedly due to violation of the law. It works such a virus very simple: prescribes its DNS servers in the network settings, and your browser finds only a fraudulent site. To solve the problem, you just need to change the DNS servers on those that fit you.

It is possible to your Wi-Fi connected too many devices. See who is connected to your Wi-Fi and disconnect the most active who "scores" the Internet channel.

Why does Wi-Fi work slowly on a laptop?

Why does Wi-Fi work slowly on a laptop?Many factors affect Wi-Fi speed. These include both external problems, and it can be in the device.

The most common reasons:

  • The laptop network adapter and the Wi-Fi router have different features.
  • Unauthorized connection occurred to your router.
  • Effect of electrical appliances.
  • Incorrect location of the router.
  • The other router affects the wireless channel.
  • Equipment is outdated.

Tip: To work your Wi-Fi faster - try rebooting the router, rearrange it to another place or update it firmware.

How to be if WiFi does not work on a laptop after reinstalling Windows

If before reinstalling Windows Wi-Fi on a laptop, it worked properly - then the reason can only be in the drivers.

Why may not work Wi-Fi on a laptop and how to fix it
Why may not work Wi-Fi on a laptop and how to fix it

Wi-Fi technology is very widely used in the life of a modern person, because it makes it easy and quickly solving the problem with connecting to the Internet without using conventional wires. This is especially true in the case of using laptops, access the Internet with which you can in any convenient place due to the presence of a built-in Wi-Fi adapter.

That is why the situation when Wi Fi does not work on a laptop, leads to significant inconveniences and even some problems. The reasons for which Wi-Fi may not work on a laptop computer, there are quite a lot. The most serious of them to solve themselves without the help of specialists simply unrealistic, but there are quite a lot of things and such that can be eliminated on their own. Consider them.

Problem in a laptop or router?

A sufficiently common problem is that the laptop stopped connecting to the WiFi network, is the problem not with the laptop itself, but with the router settings, which distributes the network. Thus, the laptop can be configured correctly, but Wi-Fi still does not turn on exactly because he has nothing to connect.

Why may not work Wi-Fi on a laptop and how to fix it
Why may not work Wi-Fi on a laptop and how to fix it

To eliminate the likelihood that the problem is related to this, you should try to connect to the network from any other device that is equipped with a Wi-Fi adapter from another laptop, smartphone, tablet, and the like.

If Wi Fi does not work from another gadget, then the problem lies in the Wi-Fi router distributing the Internet. If the connection is successful - the problem is in the laptop and before it will first need to determine - why Wi-Fi stopped working.

Hardware enable adapter

Based on such a diagnosis, it is possible to accurately determine that this problem arose exactly about the fault of the laptop. When wifi does not work on it, you can try to use in several ways.

The first one is to check whether the wireless connection adapter on the laptop is enabled. Almost all modern models have light indicators of the WiFi module and for its hardware power on there are special key combinations.

Usually, the glowing indicator indicates the on-line module. If the indicator does not shine at all or shines in red, it means that Wi-Fi does not work precisely because of the wireless adapter. It must be enabled.

Most often, such indicators are located directly on the keyboard, side or front panel of the device. Sometimes their location is found on the monitor building or near the touchpad.

To enable the module of such a network, click the Fn key combination and one of the system F1-F12. A specific combination depends on the manufacturer of the laptop. Usually the appropriate antenna icon is located on the desired key. If it is not, then to turn on the WiFay, you should try to click the standard for a particular model: • Fn + F3 for Acer; • Fn + F2 for ASUS, Dell or Gigabyte; • Fn + F5 on Fujitsu devices; • Fn + F12 on laptops HP.

After pressing the appropriate keys, check whether the operation indicator of the wireless connection module lit up or stopped burning red. After that, you should try to connect to the network again. If it did not help - go to the next step.

Software inclusion

When the WiFay stopped and the hardware switching on does not give positive results, it is also necessary to implement its software inclusion, which is carried out directly from the operating system, which is running a laptop.

To implement the WiFi software inclusion that stopped working, on Windows 7, 8 or 10, you need to perform such a sequence of actions:

1. On the notifications panel, which is located near the clock, the network connections status icon are selected;

2. From the opened list, the "Network and Shared Access" or "Network parameters" reference point is selected depending on the version of the operating system;

3. The next step is "Changing the Adapter Settings".

Among the list of all existing connections, you need to pay attention to the color of the "Wireless Network Connection" icon. If your WiFi does not work and the wireless adapter is disabled, the connection icon will not be highlighted. In this case, on its icon, click the right mouse button, from the opened context menu, select the "Enable" item. In this case, the color of the connection icons must change.

In this case, the wireless network adapter is turned on, it remains to be found in the list of available wireless networks you need and connect to it.

If, after such actions, Wi-Fi, which stopped working, continues to inactivate, you need to move to the following method of solving the problem.

Installation and Driver Update

Quite often, the Wi-Fi wireless connection is not included due to the lack of driver or in the case when it is strongly outdated. To determine the presence of the installed driver, you must from the context menu of the "My Computer" icon, which is located on the desktop or in the Start menu, select the item "Properties". Next, in the window that opens, the Device Manager command is selected from the left menu.

In the new window that opens with the list of connected devices, you must find the name of the network wireless laptop adapter. Usually its name is the "wireless network adapter" or "Wireless Network Adapter", together with which the device manufacturer should be specified: Realtek, Atheros, Qualcomm or something else.

Finding the desired item and clicking on it with the right mouse button, the "properties" are selected from the context menu. In the window, which will open at the same time, the "Device works is normal" must be present. But even if there is a mark on the normal operation of the device, this is not a guarantee that the correct driver version and Wi-Fi is installed correctly. To check it in the Wireless Properties window, go to the Driver tab and pay attention to the "Development Date" and "Supplier".

In the event that the provider is Microsoft or the program development date lags behind the current for several years - go to the official website of the laptop manufacturer and download the latest official version of the driver.

The same should be done in the event that there was no wireless adapter among the list of installed devices.

If in the list of devices, the wireless module is present, but marked with a yellow exclamation mark, it means that the device is disabled, resulting in the network and stopped working. In such a case, opening the device properties window, you need to click the "Enable" button.

Another reason why WiFay stopped working on a laptop, can be involved in economical energy consumption, which prevents the operation of the wireless connection. To disable it, you need to do the following: 1. Open control panel; 2 Select the "Power" icon;

3. In the window that opens, select High Performance or "Balanced" mode.

External Obstacles for Signal

It is also worth noting that the non-working wireless network may also be the result of not only problems with the laptop. The wireless connection signal depends on some external factors that can relax it. Ceiling, walls, gender and the like obstacles significantly worsen the quality of the access point and laptop signal.

Why may not work Wi-Fi on a laptop and how to fix it

As you know, the quality of the signal on a personal computer is displayed as several marks - the more they are, the more qualitative is the signal. If the wireless connection is displayed as 1 or 2 marks, then you can not attempt to use WiFi - in this case it will not work normally.

In this case, you need to transfer the router closer to your workplace, transfer the workplace closer to Wi-Fi Router or buy a new, more powerful router.

Other reasons for problems with Wi-Fi work

The problems described above the problems with the functioning of the wireless network adapter are most common and can be eliminated on their own.

It is worth noting that all this is software ways to solve problems that are solved by installing, reinstalling or updating the device driver, as well as the implementation of some operations with the OS.

But often the problem with the operation of the wireless connection module lies and in hardware errors. What is this mistakes? These are the problems that are associated directly from the board itself, most often its physical damage.

To eliminate such problems, you will need to disassemble the laptop. It is worth noting that it is possible to perform such actions only in the case of certain skills in this area. If there are no such skills - it is better to entrust the work of professionals.

Why may not work Wi-Fi on a laptop and how to fix it

One of the most common physical damage is the unconnected antenna wire to the contactless communication module. Such a problem occurs with laptops, which were repairing or if their owner independently cleaned the cooling system from dust. In such cases, the antenna sometimes just forget, as a result of which the adapter will not be able to establish a connection even near the source of the signal. To eliminate such a problem you just need to connect to the Wi-Fi module its antenna.

Sometimes the reason that Wi-Fi ceases to work is the usual overheating of the network card. Most often it is the result of the fact that the laptop stands on a soft surface. The whole thing is that at the bottom of the device there are holes, through which cold air, cooling all computer boards, falls inside. Broken these holes, the system overheats, which can lead to failure of certain components.

Another often encountered cause of overheating of the device is dust, which can prevent cold air intake into the cooling system.

That is why in order not to face similar problems, it is recommended to clean up the laptop dust at least once for one year: in this case, it will be possible to repair a portable PC as a result of overheating of its nodes.

In the most running cases, the wireless adapter may even burn. In this case, only his replacement for a new one will help. You can define such a problem using the device manager in which the module simply stops displayed. When you try to install the driver for a wireless network, a message appears that the corresponding device is not installed in the system.

If nothing helped

If none of the tips in the above helps, it is possible to use simple, but at the same time an effective solution: restart and computer, and a wireless router. Note, after rebooting the router turns on up to 5-10 minutes before distributing the network. Be patient. Also, despite the opinions of many skeptics, sometimes solve the problems with the wireless network helps the problem of troubleshooting, which is in the Windows operating system.

Thus, most of the existing problems of problems related to the fact that Wi-Fi stopped working on a laptop. Almost all such methods and recommendations can take advantage of anyone who encountered a similar problem, as no special skills need for this. If it does not help anything, and the wireless network did not start working, only one way out remains - go for help in high-quality service The center where any problems with the laptop can solve.

Wi-Fi technology is convenient and useful, very much needed in modern life. With it, you can connect to the Internet without using excess wires. But often the Internet users face an unpleasant problem - Wi-Fi does not work on the laptop. This failure can occur for various reasons. This article indicates possible causes of malfunctions, as well as how to make them disappear.

Wi-Fi Router

Wi-Fi does not turn on on a laptop: what's the problem

It happens that Wi-Fi disappears on the laptop, and the network icon has a red circle and a cross. Very often, the reason lies not in the gadget, but in the settings of the router, distributing the network.

To understand that it does not allow you to connect to the Internet: a laptop or router, you need to try to connect to Wi-Fi through another device, such as a smartphone. If the phone caught the network, then the problem is in the laptop. But if the connection did not take place, then the fault is failed in the router settings.

Hardware enable adapter

Each laptop is equipped with a special board - Wi-Fi adapter. Using this module, the device receives a signal from the router and a wireless connection to the Internet takes place. If the user is confident that the network does not work due to a laptop, then it should be checked if the Wi-Fi adapter is enabled, as it could turn off randomly.

Almost in all laptops are built-in a glowing indicator, which indicates that the module is turned on. The indicator can be located in several places: the keyboard (an antenna icon, distributing the signal depicted on the F2-F12 buttons), next to the touchpad, side, or front housing panel (Wi-Fi icon).

If the indicator on the buttons (F2 ... F12) does not burn or has a red color, then you need to click on it so that it turns on. Also, for connectivity, you can use the combination of the Fn + F2 / Fn + F3 / FN + F5 or FN + F12 keys (depends on the device model).

Additional Information! Some devices have a separate Wi-Fi button located on the housing.

After pressing the keys, you need to check if the indicator lit up (or stopped burning red) and try to enter the network again.

Wireless Network Indicator

How to enable device software

It may also help the Wi-Fi software connection. If Wi-Fi disappears on a laptop, then you should try to turn on the device yourself. It is necessary to do this in the "Network and Common Access Center". But get there in different ways, which depend on the operating system. The following is shown how to do it.

Features of the inclusion of Wai-fi on different versions of Windows

If Wi-Fi disappeared on the laptop, then the reason may depend on the operating system.

On Windows OS 8 or 10 you need:

  1. Go to "Start" - "Parameters" - "Network and Internet".
  2. Under the "Wireless Network" line, move the switch to "On", or go to the "Network Management Center ..." - "Changing the Adapter Settings" - "Wireless Network Connection", click on the last right mouse button (PCM) and click on "Enable "

If there is no wi-fi on the windows laptop 7:

  1. Log in to the "Control Panel" - set the "Large icons" function - "Network Management Center ...", or click on the Wi-Fi icon at the bottom of the screen and click on the "Network Management Center ...".
  2. Select "Changing the Adapter Settings" and do it all as in the previous paragraph for Windows 8/10.

After that, you will need to open a list of available networks (Wi-Fi icon at the bottom of the screen) and connect to yours.

Wi-Fi software connection

What to do when the Wi-Fi does not work after reinstalling Windows on the laptop. This failure occurs often if the system has been reinstalled. Installing a driver for a network adapter will help to solve this problem.

Features Installation and Driver Update

It happens that the network adapter driver is outdated or it for some reason is not installed on a laptop. To check the driver's status in Windows 8 or 10, you need to press the PCM to the "My Computer" label, click "Management". On Windows 7, clicking on My Computer, you need to select "Properties". Here you should search for "Device Manager".

Note! There is another way to get into the Device Manager. You need to click simultaneously on the "Win + R" keys, enter "MSC" and confirm with the "OK" button.

Next will appear, where you need to find "Network Adapters" and click on it to operate devices. Here at the row with a manufacturer of an adapter (for example, Realtek ... Adapter) can stand a yellow triangle with an exclamation mark. This means that the driver needs to be updated or installed. Either you can click on it with the right button and select "Activate" or "Enter" if there is such an item.

If the triangle is not, you will need to see the dates of the driver. To do this, the user must click on the line with the device manufacturer right-click and click on "properties". Next, you need the Driver tab, where the date of development of the installed version is indicated. If the date is satisfied with the long-time, then you should update the drivers.

Login to Device Manager

You can use the following ways to install and update the drivers.

1. Automatic update:

  • Connect the router directly to a laptop using a LAN cable.
  • Press the PCM to the manufacturer of the adapter and select "Update Drivers". The automatic search for suitable drivers will begin, and if they find them, it will install them. After that, you will need to restart the device.

2. Installing updates manually:

  • Also connect the router to the laptop through the cable.
  • Go to the official website of the adapter manufacturer and download the latest version of the drivers.
  • After installation, it is recommended to restart the laptop.

Are there external obstacles to the signal

The router may well hand out a signal if there are many obstacles between it and the laptop.

Router can not be put close to the laptop. The error is that, the closer the router to the gadget, the higher the data transfer rate will be. Just close to their location leads to a bad connection. Therefore, you need to measure the minimum distance between these devices - it should be 1.5 meters.

The best place to install the router in the apartment is a corridor - so the radius of action Wi-Fi will be distributed to all rooms, as well as a cable that comes from the entrance will not be interpreted in the house.

The smaller the barriers for the router - the better, so it is recommended to hang on the wall closer to the ceiling or put on the closet.

Important! You can not install a router next to the other technique, which will create interference for it (microwave, TV, etc.), with heating devices that provide increased temperature, in mirrors or water tanks.

Some manufacturers producing routers also offer repeaters (repeaters) - special devices for amplifying the signal. What does it mean? If the router is installed in a large room, and the network catches it not everywhere, then you can buy a repeater that receives the Wi-Fi signal and transmits it further. Otherwise, nothing will change - the network, settings and passwords will remain the same.

Principle of operation of the repeater

Other reasons for problems with work Wi-Fi network

There are several more factors, why Wi-Fi does not work on a laptop:

  • Physical damage to the network adapter. The board may overheat or burn finally. Then it will be absent in the Device Manager. To eliminate the problem, you will have to open a laptop (it is better to attribute it to a professional), then you will need to replace the board for a new one. Perhaps enough will simply clean the device from dust.
  • It is necessary to check whether the Fn, F2 keys are working until F12. If they are broken - the hardware enable adapter will be impossible.
  • Check if the router itself works. The Wi-Fi indicator, located on the router housing, should burn. You can try to restart the router with a special button, which is also on the housing ("WLAN / WPS", "WIFI / WPS" or "RESET"). After restarting, you need to try again to connect to the network.

What to do if nothing helped

If the Wi-Fi does not work on the laptop, then the possible cause of problems may be failed in the router settings. To restore them via the router web interface, you need:

  • In the address bar of the browser, print 192.168.1.1 or 192.168.0.1;
  • Enter the username and password (admin / admin or admin / 1234 - depends on the router model);
  • Find a section "Wireless Mode" / "Wireless Network" / "Wi-Fi" or "WLAN" "Wireless Settings".
  • Check whether the checkbox has a "Enable Wireless Broadcast" strings and "Enable SSID Broadcast".

This method will solve the problem when the wireless network settings for some reason began to fly.

If not one of the ways did not help, it is recommended to apply for advice to a hot line provider.

These ways to easily help solve the problem with the lack of network. You just need to carefully understand the causes of the failure and follow the instructions. If the user is not confident in his abilities, it is better to contact a specialist for accurate diagnostics.

Wi-Fi network does not work on a laptop because:

  • Banal Causes (Provider, Food, Distance)
  • Not corrected or the router is not configured
  • Problems with wifi laptop module
  • Not installed or bad network card drivers
  • Numerous nuances with Wi-Fi under Windows

This is what we will understand in this article. Most of the problems can be solved on their own, and if you can fix it to the end, and 99% of the reasons can be fixed 🙂 There I am also a video recorded where some moments are clearly visible.

Who is to blame: router or laptop?

In general, the source of the problem can be either a router or a laptop. The easiest way to find out is to connect to the Internet from another device, such as a smartphone, tablet or other laptop. If you do not connect on Wai Fay (or not the Internet), then everything is clear - we will dig in the direction of the router. If the phone works on the phone, but there is no reason on the laptop - then the reason in the laptop, but may simply be the unsuitable router settings.

Simple reasons

No matter how it was not clear to everyone, but in practice it turns out that not everyone is thinking about banal causes.

If suddenly stopped working because of a laptop

At first, look at whether the Wi-Fi module is enabled. On many laptops there is a special light bulb with a wireless sign:

Front panel indication

Accordingly, if the light bulb does not burn or glows in red, then look for a Wi-Fi module circuit breaker somewhere on the housing:

Switch on the housing

It can be on the front or sidebar, but on modern devices it is just a key combination, for example:

Keyboard shortcut

For reference, from standard combinations known:

  • Acer: Fn + F3
  • ASUS, Dell or Gigabyte: Fn + F2
  • Fujitsu: Fn + F5
  • HP: Fn + F12

Well, this is so, in general, as it depends on the model, just look for the same painted icon on the keyboard.

From simple, it still helps to restart Windows or reconnect to Wai Fay.

If Wi-Fi does not work because of the router

Next I recommend checking whether the router earned first from the phone, and then from the laptop, because It may be that with your portable computer something is wrong, and the smartphones have much less often with WiFi.

Check if the router works. Maybe somewhere knocked out the plugs or turned off the light and it stupidly does not work. Or the power supply deployed from the outlet (smoke :)), the cat has nestled, it does not matter. If it works, restart it: off, wait 10 seconds and turn on again. After 2-3 minutes, when the router boots, check whether WiFi has earned on your computer / laptop.

If after the reboot earned, but you have to do it several times a day, then most likely you need to look for a new router. Less often the reason in the provider or its settings. It is better to first call and ask why you have this happens, call the router model. Maybe he advises with what the best network will work.

Make sure that the Internet provider services are extended. You can just call or try to go to your personal account on the supplier's website. If the problem is only in this, then their site will boot. Of course you need this address to be saved in bookmarks.

Wi-Fi will not work if you get away from the router. 10 meters enough to start problems. This is if there are walls. And if not, then 15-20 meters may be decisive for most routers and laptops. The quality of receiving a wireless network can be estimated by the icon near the watch:

Signal quality

Present reasons for non-working WiFi on a laptop

The simplest think more than understandable, then you will need to pick up in the settings.

WiFi does not want to work only on a laptop

We look at the network icon near the watch. If this is a red cross:

No network icon

So Wi-Fi module is disabled. Click on the icon right-click and select "Network and Shared Access Center"

Control center

Next "Changing the adapter parameters"

Change settings

We find the connection "Wireless Network". It can be called differently, but the distinctive feature of the wireless network icon is the signal strength columns. Turn on the connection by right-click:

Enable wireless network

WiFi network does not turn on

This may be that for a while hanging "Getting an IP Address" and then the "Windows error" could not connect to ... ". It is probably not correctly indicated by the method of obtaining an IP address. We try the following:

Right-click on ""

TCP / IP.

If some numbers are prescribed in the window, then it is better to rewrite them somewhere, suddenly come out, and put everything on the machine:

Automatic receiving addresses

Try to reconnect. Doesn't Wai Fi sees? Then we prescribe such settings:

We specify manually

We try 192.168.0.2 or 192.168.1.2 to the IP address, and 192.168.0.1 or 192.168.1.1 as the main gateway, respectively, should earn in one of the options.

No wireless network at all

Most likely the Wi-Fi module driver is not installed. You need to open the Device Manager. In Windows 10, simply press the start button and select the Device Manager. Here in it carefully we are looking for problem devices:

Unidentified devices in Task Manager

If you observe a similar picture, i.e. Many devices with exclamation signs, it means that you recently reinstalled Windows and have not installed any drivers at all. So you will not only work Wi-Fi, so in general half of all will not be furious.

You need to put all the drivers. If there is a drive with drivers from the seller, then insert it. Make it with all that the master will offer. If not, then you need to read the article on the automatic installation of drivers using the program.

If the picture is simpler, with exclamation signs, only the "network controller" and / or "Ethernet controller", then we go to the site of the laptop manufacturer, section "", it is about, variations are possible. It is necessary to find the model of your laptop, it is written on the back cover. Next, it is climbing in the driver loading section, select your operating system and its discharge (how to find out -> here).

Among all the drivers, you need to find something with the words "Wireless LAN"

Broadcom Driver

Download and install. The most popular manufacturers of Wi-Fi Chips: Broadcom, Intel, Realtek, Atheros. You can detect drivers for several manufacturers for your laptop. Simply in different revisions can put different chips. How to find out what you need? The simplest to try them in turn, but in general, using the AIDA64 program you can see in the section "":

Aida64 PCI network

The screenshot shows that Wireless (wireless) network card - Broadcom, and under the cable (Ethernet) is REALTEK.

For some Lenovo laptops

If you are a "happy" owner of one of the Lenovo devices with the installed Network Broadcom, then Wanging that in Windows 8/10 you have serious problems with WiFi: the Internet works for a while, then the connection falls off, you have to connect again and so all the time. Exit only one, but it is: Install the driver version 5.100.245.200. .

Download driver 5.100.245.200 for x86 (32bit)

Download driver 5.100.245.200 for x64 (64bit)

To change the driver we go to the device manager, click right-click on Broadcom -> Refresh Driver:

Refresh Driver

Further ""

Select from the list

In the next window, remove the "Only compatible devices" checkbox and click "Install from the disk"

Install from disk

That's just at this step you need to specify the path to the folder with the unzipped file. Warnings that the driver is not suitable, ignore, we agree with everything. If after the actions done it became only worse, then just go to the Broadcom properties in the Task Manager and do "

That if the network card is not in the device manager

It may be that Networks are not even with an exclamation mark in the list of devices. This means that the Wi-Fi module jumped out of the connector or burned down. You can correct if you disassemble the laptop. Here you already see recommendations on a specific laptop, I recommend on YouTube.

Everything works, but the list of networks is empty

In this case, the switch that I wrote at the very beginning of the article can be turned off. But it may also easily be that someone forgot to connect the antenna to the WiFi module. Maybe when it was cleaned of dust, or something changed, in short, you need to disassemble and connect the antensels. Also try to update the driver for the last.

Wi-Fi antennas

Disappears after exiting sleep mode

In the device manager, go to the properties of the wireless adapter to the "Power Management" tab and remove the checkbox "Allow disconnecting this device to save energy"

Allow the device shutdown

Incomprehensible glitches, does not connect to Wi-Fay

Perhaps the network parameters on the router have changed, and the created Vi Faya old profile has changed. You need to delete it and re-find the network. In Windows 10:

Go to "Network Parameters"

Network parameters

Click "Management of famous networks"

Management of famous networks

To remove the profile "Forget" network

Forget WiFi Profile

Then you connect to WiFi as the first time. For any versions of Windows, such a method also helps to remove profile:

  1. In the search for the "Start" menu, enter "CMD", start it with the right button "Run on the name of the administrator"
  2. On the command line (in the Black Window) we write:

NETSH WLAN DELETE PROFILE NAME = "Profile name from the list of networks"

Reset TCP / IP stack

The way can help if sites are poorly open:

  1. We write on the command line:

Netsh int ip reset c: \ resetlog.log

  1. Restart a laptop.

Turn off TCP / IP auto-tuning in Windows 10

Innovations in a dozen, designed to optimize network use, in many cases leads to frequent Wi-Fi failures. We try to disable and reboot. To do this, in the command prompt, I also enter the command:

Netsh int tcp set heuristics disabled

Netsh int tcp set global autotuninglevel = disabled

Netsh int TCP Set Global RSS = Enabled

After each team, you need to see the confirmation of the successful execution of "OK". Reboot, check whether everything works as it should.

What to do if the Wi-Fi module burned or constantly buggy

Sometimes nothing helps, even though you are crazy! In this case, the most correct solution is to buy a USB Wi-Fi module (whistle).

Wi-Fi USB Adapter

Change the built-in network is more complicated and more expensive. USB "whistles" work normally, almost at the same speeds. And for the notorious Broadcom in Lenovo, even the cheapest for $ 4, the REALTEK RTL8188CU module works faster and stable 1.5-2 times!

Problems with router

Here are two options:

There is a connection, but without access to the Internet

This is when such a WiFi icon:

Without access to the Internet

This means that WiFi is connected and works, but the network is only between the laptop and the router. Those. The router is not configured or does not have access to the Internet. Look at the front panel of the router, is the WAN light flashlights / flashes? If not, then the problem with the cable from the provider, you need to call them. If the light is on, then you need to go to the adjustment of the router and configure the Internet access to the provider. How to go to the admin panel is in Look here.

Immediately make a reservation that all Internet providers have their ways to organize access. Ideally, you need to find a contract in which everything is spelled out. Well, or call technical support service.

The essence of this is: in the admin you need to go to the WAN section and make settings there from the leaf. On the example of the TP-LINK router it looks like this:

Internet on router

And since we turned out to be here, then you immediately blow the problems when sites do not open, but Skype works and the Wi-Fi icon shows that everything, type, works. We put the "use of these dns servers" tick and fit into the fields:

8.8.8.8.

77.88.8.8.

These are public Google and Yandex DNS servers, respectively. Or:

1.1.1.1

1.0.0.1

These will be new faster DNS from CloudFlare. We do it because the Dns-s (Server named) providers will very often fail, as a result, as it were, but browsers do not understand the names of sites and do not see them.

Promotional attention Why sites are not loaded in a separate article

Even if the sites work very slowly, the download is intermittent, then in the WAN sections, refer to the MTU Size parameter. If the type of connection "Dynamic IP" or "Static IP", then the value must be 1500. For L2TP: 1460, PPPoE: 1420. If you have a network via 3G modem, then put MTU 1476. This is a thin network setting, and if the connection I did not work for stable work, then you need to call the provider and ask what MTU should be used.

Another situation could arise if before you were connected directly to the cable, and then put a router. Many communication providers when the first connection is recorded by your MAC address so that no one except you can use your Internet. The computer and the router have their own unique MAC addresses. And it turns out that your router for the provider turns out to be a stranger.

You need to assign the same Mac to the router as the computer's network card. To do this, we find the "Network -> Mac Clone" section and click the "Clone Mac Address" button, save, reboot.

Cloning Mac Adder

Wi-Fi works badly, turns off

If everything worked, and then sharply stopped, or everything is loaded for a very long time and with cliffs, it is very likely that the radio channel has been hampered, which uses the router. You need to go to the admin in the "Wireless" settings section and see what channel stands:

Mixed 11bgn, Channel on Router

Must be "auto". If you do not help, you can try to choose any numbers from the drop-down list. Couples attempts are enough to understand that it's not about it.

If it does not connect to Wi-Fi at all or writes "Status is limited", then there you need to choose the mixed mode of operation "11BGN Mixed". It may be called differently, the key here is the letter "BGN". This means three WiFi-network standards. "B" is the oldest and slow, "G" - up to 54 Mbps, "N" - the most chassis for today. But go to the router will have to get from another device, because it does not work with a laptop. Or just reset it by default.

Also bad and slow communication may be due to the power scheme in Windows. With certain settings, the gear mode of operation of the adapter may be turned on. You need to change here:

Power Mode in Windows

If nothing helped

What else, sometimes helps in the router settings to set the same time zone as installed in Windows:

TP-LINK temporary zone

Also can help enable FIPS compatibility mode. To turn on go to ""

Enable FIPS mode

And in the next window, turn on the compatibility mode checkbox with the FIPS standard.

It does not prevent disable your antivirus, especially DrWeb, which can block the network.

Before throwing out a laptop in the window, try using the troubleshooting wizard built into Windows, which offers its services with each error. Strange, but they say that sometimes helps 🙂

That's all, friends, success!

WiFi does not work on a laptop

The other day there was an interesting case, which prompted me to writing this article. I got absolutely new in my hands, just purchased a laptop Hewlett Packard HP 15-AC052UR with already pre-installed "eight". The owner is a modern man and very much wanted to try the new Windows 10 operating system, so he asked me to update. No sooner said than done. The update procedure passed without a bitch and zadorinka, but later the trouble began. The first, which was caught in the eye after logging in - the laptop does not see the WiFi network. In the list of connections on the adapter icon stood a red cross. For any attempts to somehow turn on the adapter no reaction was. Well, we'll be fixed. I'll go ahead, I will say that I solved the problem and it was very specific. But I want to make a small guide on this case on this case on what to do if Wi-Fi does not work on a laptop.

Step 1. Is WiFi adapter enabled?

As practice shows, the cause of the greater half of the problems with the wireless network on laptops, netbooks and ultrabooks is that the network card is turned off. How to check it? Let's start with the Wi-Fi-Fi button - this is almost on every laptop. It can be in the form of a separate button or slider, like this:

Or combined with one of the keys F1-F12:

In the latter case, to turn on, you need to press this button in a pair with the function key FN. . If the adapter was turned on successfully, the indicator should turn around on the housing. It can be made separately and marked with an antenna icon, or is located on the power button:

Wireless Network Work Indicator

If the laptop does not respond to this button at pressing this button, then most likely you do not have a driver for function keys. In order to download it - we go to the official website of the manufacturer, open the "Support" or "Download" section and enter a laptop model in the search string. In the results found we are looking for software for function keys, download, install. Check.

Note: If you have a modern laptop, then it may be such a button "in an airplane":

Windows 10 in the aircraft

It was made by analogy with smartphones and tablets to disconnect the radio module. When it is turned on by a system tray instead of a network icon, an airplane icon appears:

It must be disabled otherwise the laptop will not see the wireless network and can be connected to it.

OK, the hardware network card turned on, and Wi-Fi does not work! And programmatically included? Let's check. We will look at the icon in the tray. If you are depicted in it:

Then skip step 1 and step 2 and immediately go to step 3. When a red cross is standing on it:

Wi-Fi does not work

This means that the network is turned off. To enable in Windows 10 there is a separate switch in the "Parameters" section -> "Network and Internet":

Windows 10 Enable Wireless Network

By the way, he did not move, or rather, when he was trying to move him to the "On" position, from himself returned to the position "Off." And I clicked on the "Setting Adapter Settings" link.

In Windows 7, 8 or 8.1 there is no such thing, and therefore will have to go to Windows connections. Press the Win + R keys combination, enter the command NCPA.cpl :

Network connection windows

Find in the list of connections The Wireless Network icon. It's gray? Then I click on it with right mouse button and select the "Enable" item.

If the WiFi adapter icon is not completely there - most likely the driver is not installed. I was all somewhere sad - the Wi-Fi adapter was active, but there was a red crossed on it.

Go to the next step.

Step 2. Is the driver for Wi-Fi?

Very often after reinstalling Windows users forget to put some drivers or install, but not those. Sometimes the network card will not work with this situation. Fix.

We go to the device manager, find the "Network Adapters" section and look at what is there. There must be a minimum of two points. The first is the usual Ethernet network card, the second - wireless.

If there is only a regular network, then see - the unknown device with an exclamation mark should be higher in the dispatcher. This is your adapter for which you need to download the WiFi laptop adapter driver from the manufacturer's website and install it.

My driver was installed, so I decided to see its status: I clicked with the right mouse button and chose the menu item "Properties":

WiFi driver for not bouquet

If everything is in order, then the "General" tab in the "Device state" field should be a stitch "The device works fine."

If some error is displayed there, you must first try to reinstall the driver. To do this again, click on the right-click adapter and select Delete. After that, you need to restart the computer, again go to the Device Manager and whether the driver has been installed.

It did not help me and I decided to update it. I downloaded the latest version from the Hewlett Packard site, in the device manager by right-click on the device and selected the "Update Drivers" item:

Refresh Wi-Fi Laptop Driver

The version was updated, the device works fine, but still does not work WiFi on a laptop. What to do?

As a result, it helped me here. On the official website, in the list of available download, I saw that for my laptop model there is a BIOS update in which compatibility problems with Windows 10 are fixed. Download the utility, run and wait until it works and restart the system:

Flashing BIOS UEFI HP

After that, the wireless laptop network earned.

Note: Install updates can be either manually or through a special utility. Each manufacturer has its own application for this. For example, Hewlett Packard is HP Support Assistant. The application will connect to the server and check the availability of driver updates. If any - you will be asked to install them.

Step 3. Does the laptop sees the WiFi network?

The hardware is checked - we take for software. Very often, users complain that the laptop does not see the WiFi network. The reason for such a malfunction can be in a laptop, and in the router, which distributes Wi-Fi. The third option is not given. How to identify the guilty? Very simple, click the left mouse button on the network icon in the tray and look at what is in the drop-down menu.

Wi-Fi with laptop connect

If the laptop sees other people's networks, but does not see her - it is necessary to check the router. If it does not see any network at all - we return to the steps 1 and 2, since the problem is most likely a hardware.

For the purity of the experiment, you can use any mobile gadget - tablet or smartphone and whether it is normal to connect. It will immediately be understood where to "dig".

As a special case, you can consider the option when the computer cannot connect to the wireless network due to an authorization error. If you have connected to it before, then in this case you should try to delete it in the list of known and connect again:

Forget Windows 10 network

In Windows 10, this is done in "Parameters Management", in Windows 8 it is necessary in the list of networks to click right-click on its own and select the menu item "Forget". If you first connect to this WiFi network, enter 100% correct password and drops over an authorization error, then the problem is in the router and you must try to start doing a purely digital key. If it does not help - try to reflash it. In 90% of cases, this allows you to successfully solve the problem.

Step 4. Wi-Fi is, the Internet is not.

Very frequent problem of novice users. Its reason usually serve incorrect Internet protocol options version 4 (TCP / IPv4). Check it as follows. In network connections Windows with the right-hand button on the "Wireless Network" with click and select the "Status" menu item:

how to set up Wi-Fi in windows 10

In the Connection Status window, click the "Details" button. Another window will open, in which we first look at the default gateway string - there must be the IP address of the router. It is usually indicated as a primary DNS server.

Now we look higher, in the "IPv4 Address" string. There must be registered IP from the router subnet (you can see an example on the screenshot). But if there is nothing in these strokes at all, or IP is registered from the subnet 169.254.x.x, then it means automatically it is not pressed from the router and manually not registered.

Click on the "Properties" button and open the "IP version 4 (TCP / IPv4)" item:

WiFi Setup in Windows 10

Here you need to register the address of the router in the "Main Gateway" fields and the "preferred DNS server". You can see it on the sticker on the bottom of the device housing (unless, of course, it was not changed). Mask is usually 255.255.255.0, and in the "IP address" field, specify any address from the router subnet. Click on OK and reconnect.

If after that a message appears that "the network without accessing the Internet", then in this case we go here.

P.S. As a conclusion, I will consider another reason why WiFi does not work on a laptop. It is the most sad - hardware malfunction of the network card. This occurs, though rarely, but still happens. Moreover, it is very often connected with a bad contact between the adapter and the antenna solder to it. In this case, only a trip to the service will help.
