Wi-Fi router tp link disappears. What if the network card is not in Device Manager

We have prepared detailed instructions for those users who do not have Wi-Fi on the router. We will also consider questions such as why the Internet does not work through a router, and what to do if the router does not work. Below is a list of solutions to the most common home router problems.

Make sure Wi-Fi is on

If you are using a laptop, make sure Wi-Fi is turned on. Most laptops have a function key to enable/disable Wi-Fi on the computer. For example, on an Asus laptop, this is the F2 key.

Make sure the wireless connection is enabled

If you have turned on Wi-Fi on your computer, but the Internet is still not working, then you should check the wireless connection. To do this, click "Start" and start typing the following text on the keyboard "View Network Connections". Then you will see the corresponding section, go to it.

The Network Connections window will display the wireless connection on the laptop. Right-click on the wireless connection and select "Enable". If you see "Disable", then the network connection is already enabled.

Make sure the SSID and security key are correct

If your computer or laptop shows multiple available wireless networks, make sure you are connecting to the correct SSID (name of your router) and that you have entered the correct security key (password). If you connect to a neighbor's router and enter the wrong security key, of course, the Internet will not work.

Make sure the Internet is working

If you're connecting to the correct router and the Wi-Fi still doesn't work, make sure the internet is working at all. It is possible that the problem is not with your computer, but that the Internet simply does not work.

Try connecting to the router through another device, such as a smartphone, tablet, or laptop. If the Wi-Fi works on another device, then it is safe to assume that the problem is with the computer.

Restart your router

If the router is not working and is not sharing Wi-Fi, the first thing you should do is to reboot it. Quite often, popular routers have errors that prevent one or more devices from connecting to the network.

You need to disconnect the power from your router, wait 10-15 seconds, then reconnect the power. Wait a few minutes for the router to reconnect to the Internet, then check the Wi-Fi on your device. If the problem is still present, try restarting your computer.

Turn off firewalls

If you have several firewalls installed on your computer, this may be the reason why the Internet does not work through the router.

To make sure that the firewall is not causing problems with your Wi-Fi connection, we suggest that you temporarily disable the firewall. If the Wi-Fi works, then you should permanently disable the firewall or even remove it.

Restore Windows to an earlier copy

If at one point your Wi-Fi stopped working on your router, try restoring Windows to an earlier copy. In some cases, bad software or incorrect settings can cause problems with your Wi-Fi adapter or problems accessing the Internet.

Reinstall your wireless device and drivers

Corrupted drivers or other problems with the wireless device may be the reason why the Wi-Fi router does not work. Make sure you don't have driver issues by following the steps below.

1. Open Windows Device Manager (right click on Start and select Device Manager).
2. In Device Manager, expand the Network adapters section to view all network devices.
3. Highlight your Wi-Fi or wireless network adapter and press the Delete key on your keyboard to remove the device.
4. Once the device is removed, close all windows and restart your computer.

After the computer boots up, the Windows operating system will automatically install the necessary drivers for the network card.

Move the router to another location

It is possible that the Internet through the router does not work for you, because the computer does not receive sufficient signal strength. Make sure the router is located close to the computer and its antennas are pointed at your device.

If the location of the router is the problem, then you should consider purchasing a Wi-Fi extender (also called an extender or extender). Install it between the router and the problem area to increase the Wi-Fi coverage area and eliminate interference.

Update your router firmware

If you've tried all the methods above and nothing helps, then you can try updating your router's firmware to fix the problem. Search the Internet for instructions on how to reflash your particular router model.

Operating system malfunction

Still not working Wi-Fi on the router? Another reason may be corrupted files in the operating system. We suggest a complete reinstallation of the Windows operating system.

Faulty hardware

If you have tried all of the above suggestions, and Wi-Fi still does not work on the router, the router itself is probably broken, or the Wi-Fi adapter on the computer. In any case, you should check the wireless connection on your computer with another router, or connect your smartphone or tablet to your router to find out for sure what the problem is.

If the problem is in the computer (laptop), then you need to take it to a service center to replace the motherboard or network card.

If the router is defective, you will probably have to buy a new one, because routers are almost unrepairable.

That's all! We examined the most common reasons why the router does not work, as well as what to do to make Wi-Fi and wireless Internet appear.

It is difficult for a modern person to imagine life without access to the World Wide Web. The times when there was only one computer in the family are long gone. Now people use tablets, smartphones, laptops that are equipped with a WiFi module. A wired router without wireless network support has already become irrelevant. It is not able to provide Internet to all available gadgets. How to be? Of course, replace it with a device that works in WiFi mode.

Previously, routers were quite expensive. Their setup required special knowledge. Now everything has changed dramatically. Router manufacturers have tried to make their devices not only accessible to every customer, but also as simple as possible. Buyers who have purchased devices from brands such as ZyXel, Asus, D-Link and others will be able to verify this. Their range includes both budget models and expensive ones.

However, even though the configuration of routers is as simple as possible, sometimes users experience failures. For example, no WiFi signal. There are many reasons for this failure. Therefore, let's figure it out together how to set up a TP-Link WiFi router and other brands, as well as fix problems with a wireless network yourself.

Wireless network: symptoms of a problem

As soon as the user first encounters failures in the operation of the router, he begins to look for reasons in the device itself. However, in rare cases, it is it that fails. As a rule, the problem lies in the settings. Moreover, it is important to note that you need to check them not only on the router, but also on a gadget that cannot connect to an access point. Most of all, users are concerned about why the router does not distribute the Internet via WiFi.

What signs may indicate a malfunction?

• There is no signal.
• Long connection time.
• Poor internet speed from the router.
• Frequent network failures and reconnections to WiFi.

If you find such signs, you will need to check the correct connection and configuration of devices.

Search for the guilty

When it is not possible to figure out why the router does not distribute the Internet via WiFi, but at the same time connects to the network, you need to find out what or who is to blame for this. To do this, a number of specific actions are carried out:

• provider cable. Its performance is checked in the following way: connect it directly to the computer and make all the necessary settings. If there are no problems with the Internet, then the reason should be looked for in the router.
• Wireless network settings. After checking the cable and connection, we can conclude that the device itself is functioning correctly. The problem may be in the wireless network configuration. There are devices that are equipped with the function of turning on / off WiFi.
• Checking devices. There are cases when the malfunction lies directly in the device that connects to the network. In order to verify its performance, it is enough to connect from another gadget.

Why does the router not distribute the Internet via WiFi? The reasons

If, with an active connection, the user cannot access the global network, then the reason for this is the errors made when setting up the router.

• Incorrect entry/determination of the IP address.
• The transmission channel is set incorrectly.
• Incorrect DNS value.

The first two mistakes are made by users themselves when creating a wireless network. And this is the reason that the TP-Link WiFi router does not distribute the Internet. The same problems are relevant for routers of other brands. As for the last error, several factors can affect the value, such as a virus on the device.

To fix such a problem, it is not necessary to contact qualified programmers. All the user needs is a cable that allows you to directly connect the Internet, a PC or laptop and, of course, the router itself.

How to set up a TP-Link WiFi router?

Devices of this manufacturer are in high demand among domestic buyers. Therefore, it would be fair to start with him. Entering the settings is standard - entering the address in the browser line. After authorization, you need to find the WAN item in the Network tab. It will prompt you to select the type of connection. You can get it from your provider. The computer has the current values ​​of the gateway, subnet mask, provided that the Internet cable is directly connected to the device. In some models, it is possible to activate automatic detection. After that, you can proceed to the WiFi network settings. To do this, you need to find the Wireless tab. In it, the user selects the Wireless Settings item. On the page that opens, you will need to enter the name of the network. Be sure to select a region for correct operation. In the line with the transmission channel, it is recommended to set Auto. Then click Save.

Now you can start protecting your network. How to change the password on a TP-Link WiFi router? All settings are located in the Wireless Security item. Entering it, the user is prompted to select the type of encryption. Most programmers advise using WPA/WPA2. By activating it, you can enter a user key. After that, be sure to save and reboot the router. If necessary, the network access key (password) is changed in the same way.

Asus routers: setting up a wireless network

In addition to the two models described above, Asus routers are popular in Russia. They are easily and quickly configured using a special program. Ideal for the novice user. In modern models, the firmware has an intuitive interface. All tabs are presented in Russian.

How to change password on Asus WiFi router if you don't remember it? Very easy. It is enough to connect the device directly to the PC via a cable. Then do a full reset. The router will reboot and the user will be able to enter all the data.

Network setup on a D-Link router

Why does the router not distribute the Internet via WiFi? In order to answer this question, you need to go to the "Network" tab. In the WAN item, check the correctness of the selected connection type. It is important to note that there are some providers that work with MAC address binding.

Most devices with new firmware have an automatic wireless network setup feature. To do this, go to the "Quick Setup" item and activate the "Wireless Network Setup Wizard". At the end, save the results. There may also be a WiFi tab. It is enough to select "Enable".

Setting up a WiFi network on ZyXel routers

In the product range of this brand, it is easy to choose an excellent WiFi router for an apartment. According to many users, these devices are characterized by reliability and high signal quality. However, sometimes there may be problems with the wireless network. The reasons and solutions have already been described above. But in order for the user to know exactly where to correct the error in the settings, the instructions below should be followed step by step.

1. Entering the settings - 192.168.1.1.
2. In the interface that opens, select the "Internet" tab and check the connection type.
3. Go to WiFi network. There, check the parameters of the network standard, channels.

It is important to pay attention to the selected signal strength.

If WIFI stops working for you, do not rush to turn to paid services of specialists or call masters at home. To help you, we have collected all the useful tips and give the most common problems and how to fix them.

So, first of all, you need to make sure that there is no Internet through a Wi-Fi wireless connection. Insert the ISP cable into the network card directly. The Internet did not appear in this case too? Call your provider's support team. The problem is not in Wi-Fi, but in the absence of the Internet for technical reasons. Make sure your internet bills are paid on time.

What to do if the Internet works, but Wi-Fi does not work?

• Try connecting to the hotspot from other devices. So, if WIFI does not work on a laptop, but at the same time you managed to connect to the same network from a smartphone or tablet, then the problem is in the laptop.
• Perform a visual inspection of the router and all cables connected to it. The RJ-45 connector or plug is damaged, the antenna contact may come off. Try turning it the other way. Very often, the router fails after a strong thunderstorm (if you didn’t turn off the router in time and pull the provider’s wire out of it). Malfunctions are easily identified by the number of flashing lights. Get the owner's manual and check which bulb is responsible for what.

If no visual damage is found, the reason is in the settings. In this material, we will not give full settings. You will find them in the instructions and in the service agreement you have with your provider. Consider only the subtleties that many miss.

How to set up a router correctly

First of all, use the setup instructions provided by the provider. Many users ask why there is no Wi-Fi, and the reason may be simple - the provider, in order to upgrade, may change some settings and not notify you about it. Therefore, it will not be superfluous to call the support service and clarify the network settings.

Enter the settings menu by entering the address indicated on the router body in the search bar. What is there to pay attention to?

• Make sure the DHCP server is enabled. Otherwise, the router will not be assigned an IP address. To do this, go to the DHCP settings and make sure that the value is set to "Started" or "Enable" (if you have an English menu).

• The data transfer channel on the router is set automatically, but sometimes it is better to choose it yourself. What threatens the wrong communication channel? Signal overlays. To check the load on channels, use the Free Wi-Fi Scanner (for Windows devices) or Wi-Fi Analyzer (for Android) applications. By setting Wi-Fi channels to the "Auto" mode, you enable the equipment to independently select and assign the optimal channel.

Channel width is a parameter that determines the maximum data transfer rate for a certain period of time. For 2.4 GHz routers, the value is set to 20 MHz, for 5 GHz routers - both 20 and 40 MHz. Setting a width of 40 MHz in a 2.4 GHz router is highly discouraged. How to switch the router to 5 GHz? Operation at 2.4 GHz occurs when using b g n protocols. N supports high throughput. But b, g are compatible with devices released more than 5 years ago. Therefore, for a 2.4 GHz router, it is better to enable bgn mixed mode. 5 GHz routers operate in 802.11a / g mode (but the Wi-Fi modules on the devices must also support it).

• MAC filtering is ideal, but can be a serious barrier to connection. The function prohibits access to the router for specific devices. Or vice versa, you can specify a list of MAC addresses in the settings - gadgets that are not included in the list will not receive access. We do not recommend experimenting with MAC addresses unless absolutely necessary. Quite often, subsequently, because of this, many users do not connect Wi-Fi and they cannot fix the problem on their own.

What to do if Wi-Fi disappears after installing Windows 10? The problem is solved by installing new drivers. They must be designed for a specific router model and under Windows 10 OS. Note that at the time of writing, not all manufacturers have released drivers that support Windows 10. You can try installing drivers for Windows 8 or contact the contact center of the company that released your equipment.

Why does wi-fi not work on a tablet and phone, but does it work on a computer?

If you do not have Wi-Fi on your iOS or Android device, the following information will be helpful for you. In many cases, the problem, again, is in the wrong settings, although the possibility that the device is “buggy” is not excluded. You can read about what to do if there is no Internet on a specific device running Android in this.

Before you start changing the settings, make a "backup" so that the result does not turn out "worse than it was."

At the first stage, remove the Wi-Fi settings from the device that you are having trouble connecting. Otherwise, even if you change the router settings, the smartphone or phone will try to connect to the network with outdated settings.

So, what do we pay attention to:

• The quality of the SSID network name. SSID is the name of the network and is what you see when you find your network in the list of networks available for connection. It must be unique. Do not use the name of your router model or common names. If the SSID is not unique and there is already an identical name, devices will have difficulty authenticating.
• You do not find your network in the list of available networks and are wondering how to connect to WIFI. It may not be there if the signal is weak or there are problems with the equipment. But also the tablet and phone will not be able to detect the network if you use closed (hidden) SSID. How to determine if hidden SSIDs are being used? Make sure the "Broadcast SSID" box is checked.

• If Wifi does not work on the phone, you should also check the encryption settings. As a rule, manufacturers recommend setting AES - Personal WPA2 encryption. But some devices connect only via TKIP. Therefore, you should try different types of encryption. Also don't forget the password.

This completes the description of the most common reasons why there is no Wi-Fi. We hope that this material was useful to you and you solved your problem.

Very often I have to answer questions related to various problems that can be observed in the process of connecting to wireless networks. When Wi-Fi does not work on a laptop. It is during the connection process that users encounter many problems. It turns out that the Wi-Fi adapter driver on the laptop is not installed, the question arises of how to enable it, or how to fix the error that appears during the connection process. But even if everything is successfully connected, then there we can expect trouble in the form of lack of access to the Internet.

I decided to write one big article in which to collect solutions to all the most popular problems and errors. The main task is to describe everything in simple language, and analyze all the options point by point, and of course write about the solutions. This guide will work for Windows 10, Windows 8, and Windows 7. As a rule, most solutions are no different in different versions of Windows. As for the laptop itself, there is also not much difference. The tips are suitable for models from ASUS, HP, Lenovo, DEL, DNS, and even for ordinary desktop computers with Wi-Fi adapters.

Based on personal experience, comments on other articles, and the features of the Windows operating system, I have identified 4 main problems that you may encounter when connecting to Wi-Fi on a laptop. I think the problem that caused you to come to this page will definitely fit one of the 4 points:

• First of all, we will figure out what to do when on a laptop Wi-Fi does not work due to the complete absence of any wireless network settings when there is no "Wireless Network Connection" or "Wireless Network" (Windows 10) connection in network connections. Also, when there is no Wi-Fi adapter in the device manager.
• Next, let's find out why laptop does not see Wi-Fi network. There may be a problem when the connection icon is crossed out with a red cross, the inscription "No connections available". Let's take a look at the different ways you can turn on your wireless network.
• There are often times when Laptop sees network but won't connect to Wi-Fi. An error occurs when connecting. Also, here I will attribute the problem when neighboring networks are displayed, but the laptop does not see the home Wi-Fi network.
• Well, let's not ignore the problem when WiFi connected but internet not working but the sites don't open. Usually, the wireless network icon with a yellow exclamation mark, and with the status "no internet access", or "restricted". True, there are times when there are no errors and everything seems to be fine, but there is still no access to the Internet.

Having described the solution to all these problems, I hope to answer the question in as much detail as possible: "why does Wi-Fi not work on a laptop." We will consider almost all cases and problems that you may encounter in the process of connecting to wireless networks. To solve various problems and errors that will be discussed in this article, I have already written separate, more detailed instructions. I will provide links to them as the article progresses.

Before moving on to any settings, I advise you to look at the instructions for connecting to wireless networks: We have, and a separate one. Especially if you are doing this for the first time. Perhaps they simply did not understand all the nuances.

If we can't connect, we'll figure it out.

Checking for a Wi-Fi adapter and driver

The first thing I advise you to do is to check the operation of the Wi-Fi adapter. Make sure it works and the driver is installed for it. At this stage, there may be two problems:

• The adapter itself is just broken (hardware failure). This happens very rarely.
• And a very common problem Wi-Fi adapter driver not installed. Or the installed driver is not working properly. This happens very often on new laptops, or immediately after installing or reinstalling Windows. If Windows 10 almost always automatically installs the driver on the wireless adapter (although not always working), then in previous versions of Windows this must be done manually. In one of the articles I already wrote,

To check this, just go to the device manager. It can be found through a search. Or press the keyboard shortcut Win+R, enter the command (can be copied) devmgmt.msc, and click Ok.

Immediately open the "Network adapters" tab. There should be an adapter in the name of which will be "Wireless", or "Wi-Fi". This is the adapter through which the laptop connects to Wi-Fi. If you have one, then pay attention to the icon next to the name. It should be the same as mine in the screenshot below.

If there is no wireless adapter:

• If you have only one adapter there, a network card (LAN), and no wireless adapter, then most likely this means that you need to install a driver.
  You need to go to the website of the manufacturer of your laptop, find your model there (most often via search), go to the driver download section, and download the driver for the Wireless (WLAN) adapter. Then, run its installation. In this case, you will need an article and. And separate.

If you have a wireless adapter but Wi-Fi is not working:

• Right click on it and select "Properties". Pay attention to what will be written in the "Device Status" window. There should be an inscription "The device is working properly."
• Again, right-click on the adapter and see if it says "Enable". If there is, select it. After that everything should work.
• Try following the steps I wrote about in the article about . Also, you can try.
• Try to reinstall the driver (links to instructions I gave above).
• See other solutions from this article, which I will write about below.

It all starts with the adapter in the device manager. If it is not there, then there will be no "Wireless Network" adapter in network connections. Also, in Windows 10 and Windows 8 there will be no buttons and sections of Wi-Fi settings.

Turn on Wi-Fi on a laptop

In most cases, all solutions to this problem come down to simply turning on the Wi-Fi module. Since it can simply be disabled. There are several ways to turn on a wireless connection. By activating the wireless module with a keyboard shortcut, or with a separate switch on the laptop case, or check and enable Wi-Fi in the Windows settings. Now we will consider all this in detail.

If the wireless network on your laptop is disabled, then most likely the connection icon will be like this (depending on how and where the module is disabled):

In Windows 7, the icon will look a little different, but the meaning is the same.

And first of all, I would probably advise you to try turning on Wi-Fi programmatically. in the operating system settings.

How to do it in Windows 7

In Windows 7, as well as in the "eight" and "ten", you can do this in network connections. Go to "Network and Sharing Center". From there, go to "Change adapter settings". Do not pay attention that the screenshots were taken in Windows 10. In all cases, the steps will be the same.

In the new window, you need to right-click on the adapter "Wireless Network Connection", or "Wireless Network", and select "Enable".

After that, look at the connection icon (on the notification bar). If a yellow star appears next to it, it means that the laptop sees available networks and you can connect to them.

If you do not see a wireless adapter in the Network Connections window, then most likely the required driver is not installed. It needs to be installed. You can check this in Device Manager. I wrote about this above.

If Wi-Fi is not working on a Windows 10 laptop

A few specific tips for Windows 10: If the Wireless Network adapter is enabled (see screenshot above), and the laptop still does not see available networks, then perhaps Wi-Fi is disabled by the button, or in the parameters. Let's check. Just click on the icon on the notification bar, and on the "Wi-Fi" button (if she is there).

Or in the settings. In the "Network and Internet" section.

Well, if you have there are no these buttons and tabs in the settings, then see the first section of this article, or a separate instruction: .

On Windows 8

First of all, check if the adapter is enabled in the "Network Connections" window (shown above).

Open Options. In the "Change computer settings" section, you need to select the "Wireless" tab. Then turn on the wireless network.

We look at the icon with the connection status. The laptop may have already seen available networks.

Turn on the wireless network with the buttons on the laptop

If the methods described above did not turn on the wireless network, then it may be possible to do it in hardware. Everything is very simple here. On almost every laptop, to enable and disable the Wi-Fi module, a keyboard shortcut is allocated, or a separate switch on the case (rare, but it happens).

Let's just take an example. On my ASUS laptop, to turn on Wi-Fi you need to press the keyboard shortcut Fn+F2. Look like this:

This will always be the Fn key + a key from the F1 - F12 row. Here are the combinations for other laptops:

Dell: Fn + F2, gigabyte: Fn + F2, HP: Fn + F12, Fujitsu: Fn + F5, Acer: Fn + F3

In some cases, this may be a special switch on the laptop case, which looks something like this:

Important point: function keys may not work properly (or not work at all) due to the fact that the appropriate driver is not installed, which is responsible for the operation of these keys.

Here's an example: in Windows 7, I have installed all the drivers from the official ASUS website, and the Fn + F2 key combination really controls wireless networks. And in Windows 10, I did not install the driver. And when you press Fn + F2, the flight mode is turned on and off.

Not even the driver, but the utility is responsible for the operation of the frequency function keys. You can download the utilities in the same section as the drivers. Download strictly for your laptop model and installed Windows. For ASUS laptops, the utility is called "ATKACPI driver and hotkey-related utilities".

I hope Wi-Fi on your laptop is still working, and you were able to connect to the required network. And now we will consider the problems that you may encounter during the connection process.

Resolving Wi-Fi connection problems

There are some of the most popular mistakes, which I will discuss below. We will not consider solutions to each problem, since I have already written about them in separate articles. I'll just give links.

If the laptop does not see the home Wi-Fi network

Provided that he sees neighboring networks, and other devices see your home Wi-Fi network. In this case, I advise you to first restart your laptop and Wi-Fi router. Then, you can try in the settings of your router. Set a static channel, but no higher than 10th. You can also change the name of your wireless network in the router settings.

If you have any other problem during the connection process, then write about it in the comments. I'll try to suggest something.

If everything is connected, but the Internet does not work

Another nuisance that can be encountered after the laptop successfully connects to the wireless network. Most likely, there will be a yellow exclamation mark next to the connection icon.

Well, accordingly, the connection status is "Limited", or "Without access to the Internet." There can be many reasons, as well as solutions. I have written two separate articles on this issue. The first one is for Windows 7, the second one is for Windows 10:

• And a separate article about the problem

In addition, there may be a case when there is no exclamation mark next to the icon, but the sites in the browser still do not open exactly. DNS error. I also wrote about the solution to this problem in the article. At the same time, the Internet in some programs can work. For example, in Skype.

Try running troubleshooting.

Most often, the following error messages appear in the diagnostic results:

These errors are relevant for all versions of Windows.

Afterword

The very situation when Wi-Fi does not work on a laptop is very ambiguous. Within the framework of one article, it is very difficult to collect all the information on such a popular problem. And when the article is very large, it is difficult to understand it. I tried to put everything on the shelves and consider all the most popular cases. I hope you found a solution to your problem.

If nothing worked, you can describe your case in the comments. I'll try to help with advice. Well, share your solutions and useful information! Good luck!

Hello friends! Now you won’t surprise anyone with Wi-Fi Internet, it is in almost every office, store, cafe and is actively appearing in homes. A large selection of routers and a small price for them only contribute to such an active installation of wireless access points. Almost everyone can afford to buy a router and install it at home, because it is very convenient and not expensive.

And if routers have become very popular, then the issue of setting up, connecting, breaking down, etc. of these same routers has become relevant. If I have already written a lot of articles on connection, settings and various errors that you can read in the ““ category, then today I want to talk about the most popular breakdowns of Wi-Fi routers and give some tips that will help you fix the device, or simply determine reason.

Today I want to talk about problems that appear unexpectedly. Like this? Well, the router worked fine for itself, distributed Wi-Fi, pleased everyone :), and then once it stopped working. It doesn't matter how it stopped working completely, or just not the way it should work. The main thing is that he used to work well and stopped working on his own. (You have not changed any settings).

It's just that the problems that appear during the first setup of the router most likely arise through incorrect settings.

The router does not respond to the connection to the mains

I'm sorry, but your router is most likely completely "dead". On every router (well, almost everyone) There are performance indicators.

And if, when the device is connected to the outlet, these indenters do not get hot, then this is very bad.

What can be done?

Well, first check if there is a power off button on the router. Here is such a button on the TP-LINK TL-MR3220:

If the button is on, then you need to check the power supply, maybe it's in it. Usually, power supplies burn out more often than the routers themselves. Perhaps the neighbors have the same router, run and ask for a couple of minutes.

If the device still does not work, then return it under warranty. And if there is no guarantee, then it is better to throw it away and buy a new one than to give it for a paid repair. Although, you can take it to the workshop, it may not be very expensive to repair it.

Why is this happening?

For many reasons. A manufacturing defect is possible, but most likely the router burned out due to unstable mains voltage, a thunderstorm, or moisture. If possible, connect the router through a voltage stabilizer. Well, or just turn it off when you see that there will be a thunderstorm now.

This was the most severe case, now let's look at lighter breakdowns.

The router stopped working, does not distribute the Internet

If suddenly there was a problem with Wi-Fi, for example, all devices stopped connecting to the router, there is a connection, but the Internet does not work, etc. then do not rush to throw your router out the window :).

First you need to find out that the problem is really in the router, and not in the device you are trying to connect. How? Just try to connect another device (laptop, tablet, phone). If only one device does not connect, then the problem is most likely in it. Well, you understand what I mean.

The problem is in the router, what needs to be checked and how to solve the problem?

1. Do not rush to immediately go into the router settings and immediately change something there. And then set it up in such a way that it will definitely not work. Believe me, I'm not just writing this :).
2. Reboot your router. Restart your computer (phone, tablet).
3. Call your ISP and ask if there is a problem on their end. Explain your problem to them. Perhaps the Internet is not working due to problems in the provider's equipment.
4. Check if you have paid for the Internet and whether it is active (You can also ask your ISP for this).
5. Check all connections. Internet cable that connects to the router. It is advisable to check this cable outside the apartment (house). Maybe you just cut the cable. On purpose or by accident, it happens.
6. Look at the case of the router, maybe there are some interesting buttons that someone accidentally switched. For example, there may be a button to turn off the Wi-Fi module. If you press it, the devices will not see your wireless network.
7. Go to the router settings and see if the settings have been lost. This may be the Internet will not work. Especially, check the WAN tab, where the settings are from the provider. If it crashes, set it up again. Here is an example article for you.
8. Try changing the channel in your router settings. Here is a detailed article. How might this affect obscure Wi-Fi issues? Perhaps your neighbors have installed a router and not one, I will introduce neighbors from above, below, on the sides. And just all the channels (or the one you are on) busy. That's when the problems begin, which are even difficult to explain.

Have you tried everything and nothing helps?

Then, I advise you to give the router for repair, again under warranty. And if there is no guarantee, then for a paid repair, or buy a new one. Before that, you can ask a friend who understands this matter (if there is one) so that he looks at the router, settings and connection.

Real case. My TP-LINK TL-MR3220 router worked fine for several months. Then, suddenly, it stopped detecting the connection of a 3G modem. I connected different modems, the modem is powered, but it does not appear in the control panel. I tried everything, even the special firmware that TP-LINK support sent me - did not help. You can read more in the article.

This I mean, if a technical problem occurs in the router (there's something going on there), this does not mean that it simply will not turn on. It can work, but it doesn't work the way it's supposed to. And it can be very long and painful to set up, flash, check, etc.

Do not suffer. You paid money for this device. Call the support of the manufacturer of the router, explain the problem to them. I'm sure no one will give you better advice than them.

If support cannot help you over the phone, they will advise you to apply for a warranty (if any). And there it is up to you to decide whether to go for repairs, or buy a new device.

Good luck!
