What to do if Wi-Fi on your laptop doesn't work? Wi-Fi does not turn on on Android: possible failures and methods for eliminating them Wi-Fi does not turn on.

If WiFi does not turn on on Android, this may be due to errors in the firmware and hardware malfunctions. Sometimes resetting the settings or flashing the firmware helps solve the problem. But in “severe” cases, it may be necessary to replace damaged components.

This article is suitable for all brands that produce phones on Android 10/9/8/7: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Attention! You can ask your question to a specialist at the end of the article.

The reason why WiFi does not turn on is software errors

The reason that Wi-Fi does not turn on may be a system failure. To fix it, reboot your device.

Increase

If the problem persists after rebooting, remember when the error appeared. If the module stops turning on after flashing the firmware, then the optimal solution would be to re-flash the device and install the official Android builds for your model.

Wi-Fi cannot be turned on or off via - it only has a radio testing tool. Therefore, if any software failures occur in the operation of the wireless network, you should perform a reset or flashing. But before you begin these operations, do not forget to do backup copy data.

Increase

If the Wi-Fi icon in the settings turns green (or highlighted depending on the model), that is, the module is actually functioning, but the Internet does not work, check the following factors:

• correct date and time setting;
• The entered access point password is correct.

If the access point's password has changed, and WiFi settings If the module on Android stores old data, the connection will not be established. To change your password, go to Wi-Fi settings. You can enter a different password into the access point settings or simply delete it and then connect again.

The reason for WiFi not turning on is hardware failure

If everything is in order with the settings and the system, but Wi-Fi categorically refuses to turn on, then you should contact service center for diagnostics. There may be a hardware problem. Among the common reasons:

• module failure;
• low-quality components on cheap devices;
• mechanical damage after an impact or fall.
• moisture ingress.

Why WiFi doesn't turn on on Android TV

If Wi-Fi does not work or does not work well on the Android TV Box, then you can solve the problem with a wired connection or using an external adapter.

In an effort to reduce the cost of the set-top box, manufacturers often sacrifice the Wi-Fi module by installing inexpensive controllers. Most models wireless connection comes as a nominal option that can be used for web surfing and other tasks that do not require high transfer speeds. Therefore, users have to look for other connection options: pull a wire or organize a connection through a cable and a router.

In this lesson we will talk about what needs to be done if the Wi-Fi network has disappeared or you cannot connect to the network from a certain device?

We will look at the sequence of actions, after which you can determine what is the cause - the Wi-Fi router or the device on which Wi-Fi does not work.

We have prepared 2 options - a text article and a video tutorial. Check out both options as they complement each other.

I recently received this question:

“hi, tell me, I bought a zyxel router.. the computer works, but the laptop does not via Wi-Fi. It says an unidentified network.. what should I do?”.

As I understand from the question, the user’s PC is connected to the router with a cable and has access to the Internet, but the laptop does not connect to the router via Wi-Fi.

In this article I will try to tell an approximate sequence of actions to solve this kind of problem. As an example, I will give screenshots of the settings of my home router TPLINK models TL-WR841N.

Stage #0. The easiest step is to start by simply rebooting both devices, perhaps one of them is “a little stuck.”

Stage #1. First, you need to check the parameters in the router settings wireless access : name for Wi-Fi hotspot, openness to discovery, communication standard. For diagnostics, you can remove the password and encryption on Wi-Fi.

"Network name"- this name should appear in the list of Wi-Fi networks on the laptop.

"Mode"- this is a data transfer mode setting, it is better to select it with the maximum number of modes.

"Enable wireless broadcasting"- this is a general activation of wireless mode.

"Enable SSID Broadcast"- this setting is so that other devices can detect the router. If you do not select this setting, you will end up with a hidden network that not all devices can connect to.

For diagnostics wireless connection protection can be disabled.

In other routers, these settings may look different, but for diagnostics they must be set in the same way.

Here is an example of settings for the router D-LINK models DIR-615:

Stage #2. On the laptop, you need to check in the device manager that the Wi-Fi adapter is working properly.

If the Wi-Fi adapter does not work correctly, then you need to reinstall the driver for it.

If you don’t have a driver or are in doubt about an existing driver, then you need to go to the laptop manufacturer’s website and search there.

After this you can do search for wifi networks, find your network, and try to connect to the router.

If the connection is successful, check your Internet access.

If the connection fails, check the connection to the router from another device, for example, a smartphone.

Stage #3. If there is no connection to the router from other devices (or there is a connection, but no access to the Internet), then the problem is most likely in the router.

In this case, you can check the antenna mount on the router, perhaps reset the settings or update the router firmware, then reconfigure the Wi-Fi settings and check the connection to it again. If these steps do not help, you will have to take the router to a service center or replace it with another one.

Stage #4. If the connection was successful from other devices, then the problem is most likely in the laptop.

In this case, you need to check the Wi-Fi settings on the laptop again, perhaps reinstall the Wi-Fi driver, or remove the Wi-Fi adapter in the device manager and find it again.

One of the reasons for failures in Wi-Fi work there may be OS updates. I recommend additionally checking whether OS updates were installed immediately before the failure occurred. If there were such updates, you can try to roll back them and check your connection to the router via Wi-Fi again.

The most radical method - reinstalling the OS - should be used in the very last case, when none of the software configuration options has brought a positive result.

If these steps do not help, then you need to take the laptop to a service center; the Wi-Fi module is usually made in the form of a separate board and you can try to replace it.

Stage #5. When everything works - Don't forget to set up a password and encryption for Wi-Fi on the router.

Tablets have long entered our lives, becoming an integral part of it. Although they have more and more functions, most owners still use their devices mainly for Internet surfing. Of course, it's very convenient. You can go to sites of interest or social media from anywhere using Wi-Fi.
However, it is with a connection to Wi-Fi on tablets running operating Android systems and problems arise, for example, Wi-Fi does not turn on on Android tablet. This article describes the main difficulties when connecting your tablet to wireless networks and how to solve these problems.
If Wi-Fi does not turn on on your Android tablet, then first you need correct setting Wi-Fi on Android tablet:
1.First you need to activate Wi-Fi through the menu interface or using the quick access buttons.
2.After turning on the Wi-Fi module, a list of available wireless networks that do not have a password will appear in the notification panel.
3.If the required network is locked with a password, you need to go to the network settings and enter the required data. After this, the network will appear in the list of active ones.
4.When choosing open network connection occurs automatically when you select a password-protected network - after entering the desired combination with a symbol in the window that appears.
5. If the password is entered correctly and the access point is configured correctly, then there should be no problems with the connection.

If Wi-Fi turns on on an Android tablet, but the tablet itself does not want to connect to Wi-Fi, then the problem is quite common. To solve it, you must follow the following recommendations:
1.Check if it is turned on.
2.Check whether the transmission is active. You also need to make sure that the router does not filter connected devices by MAC address
3.Try to disable protected networks and try to connect to open networks.
If you have problems connecting your tablet and home network WiFi
1.Check if it is possible to connect to another network. If possible, how stable is the connection?
2.If the connection to another network is active and stable, then the problem has arisen with your home access point.
3.Change home network security settings.
4.The solution may be to update the tablet firmware.
5.Try to connect to another Wi-Fi network.
6.If you accessed the Internet via Wi-Fi with the power connected, you need to turn off the power and try connecting to Wi-Fi again.
If the above tips did not help and Wi-Fi does not turn on on your Android tablet, then it is better to contact a PC repair specialist.

I have already written so many articles about solving various problems with the Wi-Fi network in Windows 10, and a few days ago I myself encountered such a problem. Now I’ll tell you everything in detail. Perhaps someone will find my information useful. Or maybe we can collect new and working solutions in the comments.

I had a problem where I simply couldn't turn on the Wi-Fi network. The driver is installed, everything seems to work, but wireless network disabled. It is not clear how to enable it. But I solved the problem. How exactly, I didn’t understand myself. In any case, I have something to tell you.

I bought an inexpensive Lenovo laptop for work. I installed Windows 10 on it. As usual, I went to the device manager and saw that there were a lot of unknown devices. The drivers were not installed automatically, including for the Wi-Fi module. It's kind of normal.

I went to the official website and found a page with drivers for my laptop model. I downloaded the main drivers and started installing. Installed the driver on the WLAN (Wireless LAN, aka Wi-Fi). Everything installed without problems. The Intel® Dual Band Wireless-AC 3165 appears in Device Manager. Great. I rebooted the laptop and realized that Wi-Fi was not working.

The problem is the following: the icon on the notification panel in the form of a wireless network with a red cross. I click on it, it says “Wireless Network – Disabled”. The "Wi-Fi" button is active. I click on it and nothing happens.

I press it a few more times and the button becomes inactive.

Fine. I went to the settings, to the "Network and Internet" section. There is a Wi-Fi tab. The network is disconnected there. I press the switch and it comes back! I press it a couple more times and it freezes (as if it turns on). But nothing happens.

I open the folder " Network connections", next to the "Wireless Network" adapter the status is "No connection".

I go to the device manager, but everything is fine there. There is a wireless adapter, and in the properties it says that it works fine.

I run diagnostics Windows networks (by right-clicking on the connection icon in the notification panel) and I see a message: “Turn on wireless communication.” With description:

To enable wireless communication On a computer, use the switch on the front or side of the computer or the function keys.

I click “Check if the problem is fixed” and get the following result: Wireless disabled – Not fixed (see article for details).

Well, that's all. Wi-Fi does not turn on, the laptop does not see available networks and nothing works.

Why can't I turn on Wi-Fi on my laptop and how to solve the problem?

It turns out that the problem is that Windows 10 for some reason “thinks” that the Wi-Fi module is disabled. This is reported after troubleshooting is completed. But it's on and working fine.

How I solved my problem: poked the F7 button. On Lenovo laptop it is responsible for turning on the "Airplane" mode. But this did not yield any results. I restarted the installation of the Wi-Fi adapter driver and replaced the driver from the list of already installed ones. I ended up with three suitable drivers. Then I downloaded and installed some additional utility for my laptop model. I also installed the power management driver. All from the official website of the laptop manufacturer.

But Wi-Fi never worked. I decided to reboot the laptop and after rebooting everything worked. The laptop saw available Wi-Fi networks and connected to my home network without any problems. Therefore, it is difficult for me to say what exactly solved the problem. I think that installing a utility that seems to be responsible for the function keys helped. But maybe I'm wrong.

Some tips:

• Restart your laptop.
• Check if the WLAN AutoConfig service is running according to the instructions.
• Try to restart the installation of the Wi-Fi adapter driver and reboot after installation.
• See if your laptop has a separate Wi-Fi switch. On newer models, function keys are used for this task. For example, FN + F2, F7, etc. It all depends on the laptop. The function key should have an image of a wireless network or an airplane (Airplane mode).
• Install all drivers for your laptop model from the official website. Also look at the utilities. Especially the utility that is responsible for the operation of the function keys. Something like Utility for Windows 10, System Interface Foundation for Windows 10, Energy Management, Hotkey Features Integration, ATKPackage.
• Try replacing the driver according to the instructions.
• Remove the Wi-Fi adapter from Device Manager and restart your laptop.

Solution via Windows 10 Mobility Center

Update: Another solution was suggested in the comments. When I wrote about solving a similar problem in Windows 7, I described there a method by which it was possible to launch wireless communication through the Windows Mobility Center. To be honest, I thought that this mobility center was removed in Windows 10. But no. As it turns out, it can be found and launched through a search.

Let's launch. There should be a "Wireless" setting. And the message: "Wireless disabled." Just click on the "Enable..." button.

Everything should work. I checked everything on my computer. I have the Mobility Center, but I don't have Wi-Fi setup. I don't know, maybe it depends on the update. In any case, this information will not be superfluous. Maybe it will be useful to someone.

Be sure to write in the comments if you managed to turn on Wi-Fi. What helped and how we solved this problem. You can also describe your case if it is somehow different from what I had.

Wi-Fi technology is very widely used in the life of a modern person, as it allows you to easily and quickly solve the problem of connecting to the Internet without using conventional wires. This is especially true when using laptops, which can be used to access the Internet in any convenient place thanks 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 inconvenience and even some problems. There are many reasons why Wi-Fi may not work on a laptop computer. It is simply unrealistic to solve the most serious of them on your own without the help of specialists, but there are quite a lot of them that can be eliminated on your own. Let's look at them.

Is the problem with your laptop or router?

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

To rule out the possibility that this is the problem, you should try to connect to the network from any other device that is equipped with Wi-Fi adapter– from another laptop, smartphone, tablet, etc.

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 solving it, you first need to determine why Wi-Fi stopped working.

Hardware enable adapter

Based on such diagnostics, it is possible to accurately determine that this problem arose precisely because of the laptop. When Wi-Fi does not work on it, you can try using several methods.

The first one is to check if the wireless adapter on your laptop is enabled. Almost all modern models have light indicators for the operation of the WiFi module and there are special key combinations to enable it in hardware.

Usually glowing indicator indicates that the module is turned on. If the indicator does not light up at all or lights up in red, then Wi-Fi is not working precisely because of the wireless network adapter. It must be turned on.

Most often, such indicators are located directly on the keyboard, side or front panel of the device case. Sometimes they are located on the monitor body or near the touchpad.

To enable the module of such a network, press the key combination Fn and one of the system keys F1-F12. The specific combination depends on the laptop manufacturer. Usually, the corresponding antenna icon is located on the desired key. If it is not there, then to turn on Wi-Fi you should try pressing standard for specific model combination:
Fn+F3 for Acer;
Fn+F2 for Asus, Dell or Gigabyte;
Fn+F5 on Fujitsu devices;
Fn+F12 on HP laptops.

After pressing the corresponding keys, we check whether the wireless connection module operation indicator lights up or whether it stops glowing red. After this, you should try to connect to the network again. If this does not help, move on to the next step.

Software enablement

When Wi-Fi stops working and turning it on in hardware does not give positive results, you also need to turn it on in software, which is done directly from the operating system the laptop is running.

To programmatically enable WiFi that has stopped working on Windows 7, 8 or 10, you need to perform the following sequence of actions:

1. On the notification panel, which is located near the clock, select the network connection status icon;

2. From the list that opens, select “Network and Sharing Center” shared access"or "Network settings" depending on the version of the operating system;

3. The next step is “Changing adapter parameters.”

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

In this case, the wireless network adapter turns on, all you have to do is find the one you need in the list of available wireless networks and connect to it.

If, after such actions, Wi-Fi, which has stopped working, continues to be inactive, you need to move on to the next method of solving the problem.

Driver installation and update

Quite often, the wireless Wi-Fi connection does not turn on due to the lack of a driver or when it is very outdated. To determine availability installed driver, you need to select “Properties” from the context menu of the “My Computer” icon, which is located on the desktop or in the “Start” menu. Next, in the window that opens, select the “Device Manager” command from the menu on the left.

In the new window that opens with a list of connected devices, you need to find the name of the laptop’s wireless network adapter. Usually its name is “Wireless network adapter" or "Wireless Network Adapter", along with which the device manufacturer must be indicated: Realtek, Atheros, Qualcomm or something else.

Having found the desired item and right-clicking on it, select “Properties” from the context menu. In the window that opens, there should be an item “Device is working normally.” But even if there is a mark indicating the normal operation of the device, this is far from a guarantee that it is installed correct version drivers and Wi-Fi turn on correctly. To check it, in the properties window wireless device go to the “Driver” tab and pay attention to the “Development date” and “Supplier” items.

In the event that the supplier is Microsoft or the date of development of the program is several years behind the current one, go to the official website of the laptop manufacturer and download the latest official version drivers.

The same should be done if there is no wireless adapter among the list of installed devices.

If the wireless communication module is present in the list of devices, but is marked with a yellow exclamation mark, this means that the device is disabled, as a result of which the network has stopped working. In this case, opening the device properties window, you need to click the “Engage” button.

Another reason why Wi-Fi stopped working on a laptop may be that the energy-saving mode is enabled, which prevents the wireless connection from working. To disable it, you need to do the following:
1. Open Control Panel;
2. Select the “Power Options” icon;

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

External obstacles to the signal

It's also worth noting that a broken wireless network can also be the result of more than just laptop problems. The wireless signal is affected by some external factors that may weaken it. Ceilings, walls, floors and similar obstacles significantly degrade the signal quality of the access point and laptop.

As is known, the signal quality is personal computer is displayed in the form of several marks - the more there are, the higher the quality of the signal. If the wireless connection level is displayed as 1 or 2 marks, then you don’t have to try to use WiFi - in this case it will not work normally.

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

Other causes of Wi-Fi problems

The causes of problems with the functioning of the wireless network adapter described above are the most common and you can fix them on your own.

It is worth noting that all this is software methods solutions to the problem, which can be solved by installing, reinstalling or updating the device driver, as well as performing certain operations with the OS.

But often the problem with the operation of the wireless connection module lies in hardware errors. What are these errors? These are problems that are directly related to the board itself, most often due to its physical damage.

To fix such problems, you will need to disassemble the laptop. It is worth noting that such actions can only be performed if you have certain skills in this area. If such skills are missing, it is better to entrust the work to professionals.

One of the most common physical damages is an unconnected antenna wire to the proximity module. This problem occurs with laptops that have been repaired or if their owner independently cleaned the cooling system from dust. In such cases, the antenna is sometimes simply forgotten, as a result of which the adapter will not be able to establish a connection even near the signal source. To fix this problem, you just need to connect its antenna to the Wi-Fi module.

Sometimes the reason that Wi-Fi stops working is simple overheating network card. Most often this is the result of the laptop being placed on some soft surface. The thing is that at the bottom of the device there are holes through which cold air enters, cooling all the computer boards. By blocking these holes, the system will overheat, which can lead to failure of certain components.

Another common cause of device overheating is dust, which can prevent cold air from entering the cooling system.

That is why, in order to avoid such problems, it is recommended to clean the laptop from dust at least once every year: in this case, it will be possible to avoid repairing the laptop as a result of overheating of its components.

In the most extreme cases, the wireless adapter may even burn out. In this case, only replacing it with a new one will help. You can determine this problem using the device manager, in which the module will simply no longer be displayed. When you try to install a driver for a wireless network, a message appears stating that the corresponding device is not installed on the system.

If all else fails

If none of the tips above helped, you can use a simple, but often effective solution: restart both your computer and your wireless router. Please note that after a reboot, the router turns on for up to 5-10 minutes before it starts distributing the network. Be patient. Also, despite the opinion of many skeptics, sometimes the troubleshooting function that is included in the wireless network helps to solve problems with the wireless network. operating system Windows.

Thus, most of the above have been listed existing solutions problems related to the fact that Wi-Fi stopped working on the laptop. Almost all such methods and recommendations can be used by anyone who is faced with a similar problem, since this does not require any special skills.
If nothing helps, and the wireless network does not start working, there is only one option left - go for help to a quality service center, where they can solve any problems with the laptop.
