Why did the Wi-Fi router stop working? Wi-Fi Internet stopped working through the router

Adviсe

Such a problem, when the router does not distribute Wi-Fi, but there is Internet on the computer, can overtake any user. Here we will tell you about the causes of difficulties and provide step-by-step solutions - our instructions will help even a beginner get rid of problems!

The device works, but there is no connection

The first part of our review will answer the question why the router does not distribute Wi-Fi, but there is Internet. There are several causes and solutions to this problem.

#1. The first reason why the router does not distribute the Internet via WiFi to the computer is a temporary failure. It may be due to device overload:

Press the power button, wait ten to fifteen seconds and turn the device on again;
Check that the date and time are set correctly;
Try re-creating the connection on your computer.

A temporary glitch most often goes away on its own after a reboot. If this doesn’t help, let’s look at why the router stopped distributing Wi-Fi, but there is Internet.

#2. The second option is cable problems:

First, check that the Internet cable is connected to the WAN port, indicated in blue;
Make sure that the cable going to the computer goes into the yellow LAN port.

If the indicators on the device do not light up, check the condition of the cable for breaks, kinks or other mechanical damage. If there are any breakdowns, the wires must be replaced.

#3. What to do if the router does not distribute WiFi, but there is Internet: the reason may lie in problems with the device itself.

This is indicated by the following parameters:

The computer does not see;
The speed of work drops critically;
The connection is extremely unstable.

First, you should try connecting another device to the network - a smartphone, tablet or laptop. Didn't help? Then the problem lies in the hardware:

Press the router's on/off button and make sure the wireless network indicator light comes on.
If this does not help, then you need to take it to a technician for repairs or replace the equipment.

Correcting system settings

Let's move on to correcting the operating system configuration settings that affect the fact that the router works but does not distribute WiFi:

Open the Start menu on your computer and go to Settings;

Find the “Network and Internet” icon;

Enter the “Network and Sharing Center”;

Find the required connection and click on the “Properties” button;
In the new window, find the line “TCP/IPv4 protocol” and click the “Properties” icon again;

Opposite the lines with the IP address and DNS addresses you need to enter your own values;

Click the save changes button and restart your computer.

Changing the address in the adapter settings

The TP-Link router does not provide Wi-Fi, but there is Internet, what should I do? The following instructions are also suitable for other models - we will change the address in the settings of the adapter itself:

Enter your IP to log into the web interface;
You can find the required address on the back of the device - it is printed on a special sticker;
Enter your password and login. The standard pair is shown on the same sticker if you have not changed the combination;
Go to the “Wireless Connection” block;
Go to the settings tab;
In the Channel field you need to erase the automatic value and enter your own channel.

Changing Wireless Network Settings

You have performed all the steps described above, but the situation remains the same: the Rostelecom router does not distribute Wi-Fi, but is there Internet on the computer? In fact, no matter what model you are talking about, try debugging your wireless network settings:

Repeat the steps above and log into the web interface;
Log in to the system;
Go to the “Wireless Network” tab;
Find the settings line and enable the items shown in the image.

Finally, let’s figure out why the router doesn’t distribute Wi-Fi to the phone or PC, what else could happen? Problems may be caused by problems with the provider:

Call your provider's hotline;
Ask a question to a call center specialist.

Distribution is in progress, but there is no connection

Let's consider what to do if the router distributes Wi-Fi, but the Internet on the computer does not work. First you need to take preventive measures:

Reboot your router;
Reboot the connected device;

Make sure that no cable is broken or bent;
Check that the wires are connected to the correct ports.

Why is WiFi not distributed from the router if you have checked all the above indicators? You may need to adjust your hardware settings:

Log in to the web interface and log in to the system;
Open the “Wireless Network” section;
Find the DHCP settings and enable the server.

Now you know how to deal with the problems that arise!

Most often, problems with Wi-Fi routers arise during the setup process. Generally, when a router is configured correctly, it just works and does its job. But even after working for some time, the router can break down at any moment. And if it's not a hardware failure (when there is something with the board itself, the power adapter), then you can try to solve the problem yourself and fix your wireless router.

In this article I will write about possible solutions to the most common problems that can happen to your router. First of all, let's look at the problems that many people encounter when setting up a router. We will also try to deal with the main breakdowns that may appear suddenly. When the router was working perfectly, and at one point some problems, errors and other malfunctions began. Doesn't distribute Wi-Fi, the indicator doesn't light up, doesn't see the cable, doesn't go into settings, breaks the connection - all this is from the same story.

I have already written separate instructions about solving the most popular problems, links to which I will definitely leave in this article. Well, I formed the list of the most common breakdowns from my own experience and comments that visitors leave on various posts on this site. These recommendations will come in handy regardless of whether you have Windows 10, Windows 8, or Windows 7. It also doesn’t matter what manufacturer your router is: ASUS, D-Link, TP-Link, Tenda, Netis, ZyXEL, Xiaomi, etc. .d.

Below we will look at solutions to such problems:

Doesn't go into router settings. The settings page at 192.168.0.1 or 192.168.1.1 does not open. Login and password do not work.
The Internet indicator (WAN) does not light up, there is no response to connecting the cable from the provider, the WAN is disconnected. No internet connection (Internet provider). After setup, the Internet works only on one computer. The Internet does not work via Wi-Fi, or only works when the computer is turned on.
The router does not distribute Wi-Fi, or there is a network, but the Internet does not work. Laptops, tablets, smartphones and other devices do not see the Wi-Fi network.
Unstable operation of the Wi-Fi network. Low internet speed over wireless network.
The Internet disappears "without access to the Internet." Only rebooting the router helps.
The settings page is displayed crookedly and the router settings are not saved.
The indicators on the router do not light up as usual.

Instructions for solving other problems and errors:

When the error appears.
Several solutions to the problem when .
– solution in Windows 10, Windows 8, and Windows 7.
General, large.
. Including through a router.

Some important tips:

1 To begin, simply reboot your router. Turn off the power for a minute and turn it on again. Maybe this will solve your problem and get everything working. 2 If possible, connect the Internet directly to the computer. Perhaps the problem is on the provider's side. Also make sure you have paid for the Internet. You can call your provider's support. 3 If your Internet does not work on one device, be it a laptop, PC, smartphone, tablet, TV, then the problem is unlikely to be in the router. Check out the articles I've linked above. The solution you need may already be described there.

Problem setting up the router. Can't login to admin panel

First of all, we will look at the case when we are unable to log into the control panel of the router. This is the same “admin panel”, page with settings, personal account, web interface, etc. If we cannot access the settings of our device, then accordingly we cannot configure it, or change some parameters.

As it usually happens. From the device that is connected to our router, we go to the IP address 192.168.0.1, 192.168.1.1, or by hostname (address of letters). And an error appears in the browser that the page is unavailable.

Important point! In order to access the router settings, you do not need an Internet connection. The connection status on your computer may show a yellow exclamation mark.

Main reasons and solutions:

The device you are trying to access settings from is not connected to the router. The connection can be either via cable or Wi-Fi. Check the connection.
Some IP settings are registered on the computer. You need to set automatic receipt of addresses. For more information about this, see the article linked below.
Make sure you are going to the correct address. Usually the address is listed on the router itself.
If possible, try logging into the web interface from another device.

No internet connection. Problems with WAN. Internet only works on PC

The most important thing in setting up and operating a router is the correct configuration of the connection to the Internet provider. This is very important. Now I will try to explain everything in simple language. Every internet service provider uses some type of internet connection. It could be:

Dynamic IP– a popular type of connection for which you don’t need to configure anything. The computer or router itself receives the address from the provider and everything works.
Static IP- rarely occurs. To configure it, you need to register static IP addresses issued by your provider.
PPPoE, L2TP, PPTP– popular connection types, to configure which you need to specify a username, password and/or server address.

After installing the router, we go to its control panel. In the section where Internet connection settings are set. It is usually called "Internet", "WAN", "Internet". In this section, we select the type of connection that our provider uses and set the necessary parameters. Which are issued by the provider when connecting to the Internet. On TP-Link routers it looks something like this:

Of course, on devices from different manufacturers, these settings will be different.

If you had the Internet connected to your computer, and a high-speed connection to the provider was configured on the computer, then after installing the router you do not need to start it. We simply configure this connection on the router, and it will launch it itself. And we simply connect the computer with a network cable. Without starting any connections.

It is precisely because the router is not configured correctly that the Internet may not work on the devices connected to it. There will be an error "No Internet access". I wrote a separate instruction about this: .

Sometimes it happens that the Internet only works on one computer, or only when the computer is turned on. All this is also due to incorrect settings. Or when you run a high-speed connection on a PC. I also wrote about this: .

I think we've sorted this out.

Problems with the Wi-Fi network on the router

This malfunction should be divided into two categories to avoid confusion. Because the solutions there will be different.

When the router does not broadcast the Wi-Fi network at all. Your laptops, tablets, smartphones do not see the network.
When there is a Wi-Fi network, devices will connect to it, but the Internet does not work. No internet access.

People often write to me saying that the router has stopped distributing Wi-Fi. And try to understand, the wireless network has completely disappeared, or it is there, but the devices do not access the Internet. Let's look at these two situations.

When the wireless network disappears completely

Reboot the router. If it doesn’t help, then check the button that is responsible for turning off and turning on the wireless network. It is available on a large number of models. It looks something like this:

It may have been pressed accidentally.

Also, please note that for some reason the router may have reset the settings, and now the Wi-Fi network has a standard name. It is indicated on a sticker on the bottom of the device.

When there is Wi-Fi, but no Internet

We also first reboot the router. Let's see if the Internet has disappeared on all devices, including cable. It would be nice to connect the Internet directly to the computer and check if it works. Maybe the provider has some kind of problem.

I wrote in more detail about these problems in the article:. Both problems are addressed there. Everything is detailed and with screenshots.

Slow Wi-Fi speed and unstable wireless connection

As for the speed of the Internet over a wireless network and the stability of this network, everything is very ambiguous and blurry. When you install a router, you need to be prepared for the fact that the speed will be lower than via cable. And the speed of the Wi-Fi network itself depends on a large number of different factors: the router, the speed provided by the provider, the type of connection, interference, the number of neighboring networks, the signal level, the device you are connecting, etc. I have already talked about.

Some tips:

Check the cable speed to see how much lower it is over the air.
Try changing the channel of your Wi-Fi network. Read how to do this.
Test speed on different devices. Perhaps the problem is in the client itself (device you connect). It may have an outdated wireless adapter installed. You can try updating the wireless adapter driver (if it's a computer or laptop).
You can experiment with the network operating mode settings and channel width. Read more about this at the link below.
Update your router firmware. If it turns out that the problem is there.
Transition to 5 GHz frequency. If the speed is poor due to interference or a large number of neighboring wireless networks, then it may make sense to think about choosing Wi-Fi support at a frequency of 5 GHz. Might be useful: .

As for the unstable operation of the wireless network, you can apply the tips that I wrote about above. Or just follow the link: .

The router has to be rebooted frequently

This problem looks like this: everything works, the devices are connected, the Internet is available, and at one moment access to the Internet disappears. On computers, a yellow exclamation mark appears next to the connection icon. This happens on all devices simultaneously. Reboot the router (turn off and on power), and everything works again, until the next such break.

The Internet may disappear several times per hour, day, week. But this is a little annoying, you constantly need to reboot the router. If you do not reboot, access to the Internet will not appear. Of course, I cannot say with complete confidence, but most often this problem arises with budget, weak routers, or already old devices. And most likely the break occurs precisely at the moment of increased load on the router. Video, online game, torrent, etc.

Why does this happen: due to some hardware problems on the board of the router itself, or in the power supply (as often happens), it simply cannot withstand the load and freezes. It’s difficult for me to explain this from a technical point of view, but we don’t need it.

What you can try to do in this situation:

Update the firmware. This is the first thing to do.
Disable programs on your devices that may overload the network. For example, torrent clients. If you don't download anything.
You can reset the router settings and configure it again. Maybe some parameters were set there earlier that you have already forgotten about, and which affect the operation of the network device.
See if your router is getting hot. Place it in a place where it will cool well.
If you have a lot of devices that create a heavy load on the network, and all this on different devices at the same time, and at the same time you have a budget router for $15, then most likely you will have to change it to a more powerful one. Especially if you observe breaks at times of increased load.

Settings are not saved, the web interface is displayed crookedly

I often hear about problems when the router does not want to save the specified parameters. After clicking the save button, either nothing happens or some error appears. Also, there are often cases when the settings page is displayed somehow crookedly. There are some sections missing, inactive links and buttons, everything has moved out, etc.

Whenever you encounter such cases, the first thing to do is try setting up from a different browser. Or better yet, from another device.

If the router still does not save the settings, then try to reflash it. Or return it to the store (if it's new). Since it is possible that this is a hardware failure. And the settings may disappear after each power outage. And this is not normal, it shouldn’t be like this.

The indicators on the router are lighting/blinking incorrectly

Indicators, which are found on almost every router, signal possible malfunctions or breakdowns. For example: if the Wi-Fi indicator does not blink, then the wireless network is not working for some reason.

What a specific indicator is responsible for and its operating modes should be described in the instructions that were included in the kit. Depending on the manufacturer and model, this information may vary.

If, for example, all the indicators are on and do not go out, or only the power light is on, sometimes with an indicator in the form of a gear, then this very often indicates a hardware failure of the router.

And if this happened during a firmware update, then perhaps there is a chance to restore the router. How I did it with TP-Link in .

But as practice shows, the strange behavior of the indicators on the router means a breakdown in the hardware. The first thing you need to do is reset the settings. But this doesn't often help. And in most cases you have to buy a new router. Since repairing this equipment is not always justified. So it might be useful to you.

Afterword

Of course, it is impossible to collect all the problems and their solutions within the framework of one article. In addition, there are a lot of different manufacturers and different models of routers on the market, everyone has a different Internet connection and different devices. And a lot depends on this. Those same errors, symptoms and problems can vary greatly. Well, you need to understand that this is technology, and any technology breaks. Sometimes there are such cases and breakdowns that it is simply impossible to give them some kind of logical explanation.

When some kind of malfunction appears, many are simply sure that it is something in the settings. You just need to press one button and everything will work. Perhaps I will upset you, but this is not so. More precisely, this is not always the case. Routers often break down, something burns out in them, power supplies fail, LAN and WAN ports burn out. It is clear that it is almost impossible to fix this with your own hands and at home.

To understand what the problem is and how to solve it, try to analyze why the malfunction occurred, what could be the problem, how other devices behave, etc.

Be sure to write in the comments. Ask questions, share tips and your observations on this topic. Best wishes!

When setting up a Tp-Link router for the first time, the following problem occurs: everything is done correctly, but your device does not distribute the Internet or Wi-Fi.

Let's try to deal with the most frequently occurring situations:

We turned on the router, but the Wi-Fi network does not appear and is not displayed on devices connected to the router.
There is a Wi-Fi network, but it is impossible to access the Internet. In this case, the network on the computer is reflected as “No Internet access” or “Restricted”.

These problems periodically occur on any device, but if your router is not Tp-Link, read article.

The Wi-Fi network may not work for various reasons. However, most often they are associated with hardware problems. Therefore, use multiple devices to test the connection. If the Internet does not work, usually during setup mistakes were made when entering parameters for connecting to the provider.

Consider the case when there is no Wi-Fi connection. Let's say you recently purchased a router and are setting it up for the first time; you left a standard name for the Wi-Fi network (for example, “TP-LINK_9415E8”). As a result, it will be difficult to find your network among others. To get rid of this problem, go to the router settings and enter a new network name. How to do this correctly is explained in the instructions for setting up the router.

Then find the button on the router case that turns on the Wi-Fi network. As shown in the figure, on Tp-Link routers this button is usually located here; when pressed, it is recessed into the body.

To find out if a Wi-Fi connection is established, let's check the Tp-Link settings of your device.

When the wireless network is unavailable, connect to the router via cable, then go to the settings. Enter the address or in the browser and go to the desired page. There we will indicate the user name - admin and the password for logging into the network - admin. If something doesn't work, carefully study the step-by-step instructions.

In setup mode, go to the “Wireless Mode” tab ( Wireless), and check if the checkbox next to “Enable wireless broadcasting” is checked ( Enable Wireless Router Radio), which is responsible for turning on Wi-Fi. If you don't have it, install it to connect the wireless network.

In addition, you need to check how well the removable antennas are attached to the router, as well as what the Wi-Fi indicator shows.

Why doesn't the Internet work via Tp-Link?

A situation often arises: the router has been configured successfully, all equipment is connected to Wi-Fi through it, but for some reason the Internet does not work. When the router is connected via a network cable, but there is no access to the Internet, to fix this problem you need to:

check and correct information for the Internet provider in the settings;
check whether the cable is connected correctly to the WAN connector of the router.

Usually on the computer in the settings it is found connection status “No Internet access” or "Limited" (for Windows 8 and Windows 10). You can read how to fix this problem here. On TVs and various mobile devices (smartphones and tablets), you will not be able to run programs that use Internet access or log into any website.

What problems may arise when connecting to the Internet during the first setup of the router can be read in the article: when setting up the router it says “No Internet access” or “Restricted” and there is no connection to the Internet.

What to do if you cannot access the Internet?

If you have one of the Tp-Link routers, you need to check:

the provider's network cable is correctly connected to the router;
the settings are correct for your connection type.

Connect a network cable to the blue connector of the router (the wizard installed it when connecting to the Internet) or a cable from the ADSL modem. The figure shows how to correctly connect the cable to the WAN connector.

When you connect a network cable to the router, you can usually access the Internet. If this does not happen, there may be problems with the equipment of the provider, or you need to pay for using the Internet.

If you have connected the equipment correctly, but it is impossible to access the Internet, let’s check whether you made a mistake when setting up the equipment. Let's go into setup mode, go to the "Network - WAN" tab ( Network-WAN), in it we will select the connection type that corresponds to your Internet connection. Then fill in all the fields in the window that opens.

Every user sooner or later is faced with the fact that for some reason Wi-Fi does not work on the phone. This article is designed to help you identify the sources of these common problems and find the fastest and most effective way to fix them.

Why doesn't Wi-Fi work on my phone?

Wireless communication malfunction is usually caused by several reasons:

Incorrect Wi-Fi settings.
Errors in the operation of the router itself.
Incorrect mobile device parameters.
The action of malware or antivirus software.

Below we will look at each item in detail and formulate recommendations for troubleshooting. All of the following is relevant both for Wi-Fi on an Android phone, iOs, and for other operating systems.

Troubleshooting

You can cope with the problem only if you accurately determine its cause. To do this, you do not always need to contact specialists. Many errors that relate, for example, to wireless mode parameters, can be identified independently. If the Internet slows down or works slowly, this may be due to third-party factors: for example, network overload when many gadgets are connected to it. Sometimes slow Wi-Fi is a reason to check the computer itself or the communication line of your Internet provider.

Incorrect Wi-Fi setting

First of all, you should pay attention to how the Wi-Fi access point is configured. To do this, you need to access the router menu through a browser: but you will need to enter a series of characters in the address bar, the combination of which is individual for each device. Usually this data is located on the back of the router, look for the Login and Password lines, they will be needed in the next step.

Enter your username and password. If you managed to gain access to the menu, first of all you should pay attention to the wireless mode parameters. There are a few simple options here:

Channel - Auto, but you can try setting a different channel.
Mode - 11 bg Mixed, but changing the parameter to 11 bg only can give a positive result.
Channel Width - auto.
The transmission speed, if any, is set to the maximum value.
Region has little effect, but theoretically it can be a source of malfunction.

If everything is configured correctly, but the Internet still does not function correctly, you should contact a service center or look for the problem elsewhere, for example, by contacting your ISP. The device may be technically faulty, so it is recommended to check it immediately after purchase.

Router settings

You should check whether it is possible to access the Internet at all. If it is not there either from a personal computer or from another device, it is advisable to check whether the router itself is turned on and whether it is working correctly. Indicators signal this.

The power indicator should be green. Next to it is a system indicator that should blink. The next indicator, WLAN, shows whether wireless is enabled on the router itself or in its menu. Next are numbered LAN ports, to one of which a cable must be connected. Ideally, it should also blink. After them usually comes WAN, the indication of which indicates that the router is connected to the Internet.

In some cases, reconnecting helps.

Incorrect time or date

Wi-Fi on a mobile device may not function well due to such a small thing as an incorrect date - this is one of the first on the list of common causes of Internet problems. You just need to go to the time settings section and set the correct values. It is important to take into account the time zone correctly.

Wi-Fi password error

Another possible reason is the password. If the phone connects to the hotspot automatically, this error occurs when the user changes the password. In other words, the password has been changed, but the gadget itself “does not know” about it and automatically enters the old one. The solution, again, is simple - create the connection again and enter the correct password.

Malware and antivirus programs

Viruses that the smartphone has “caught” on the network can also interfere with the correct operation of Wi-Fi. If you suspect an infection, it would be advisable to install an antivirus program on your phone and run a scan. There are many such programs, but they usually use established brands like Kaspersky and ESET Nod.

The other side of the coin: antivirus and other security programs, such as a firewall, can themselves be a source of problems. The antivirus creates a kind of “shield” to filter traffic, which sometimes affects communications. If after removing the anti-virus software the connection works correctly, in this case you will have to try another software or abandon it.

Software glitches

For many users, wireless communication fails due to incorrect software operation. For example, when the user installs alternative firmware or makes any other interference with the factory characteristics of the software.

Problems with the Android system are also evidenced by other errors in the operation of the gadget - constant, systematic freezes, random shutdowns, and others.

In this situation, you can do a Hard Rest - it will return the system to factory settings.

If the problem is with the phone's firmware, this will help solve it. But you need to know that “non-native” firmware is not deleted in this way.

Rebooting the Router

When the source of incorrect operation lies in the router, you often just need to reboot the router. This is not always easy to do, since some models are not equipped with an on/off button.

If the device itself does not have a reset function, you can simply unplug the cable for 10-30 seconds.

It can also be done through the device menu. The procedure for entering there is described above. This method is relevant if it is difficult or impossible to get to the router itself. The “Reboot” option is located in different parts of the menu in different router models, but, as a rule, on the system settings tab.

Rebooting the mobile device

If the error in Wi-Fi operation is due to software glitches, you can try rebooting the device. In addition to the standard “Restart”, there are several more radical and thorough methods:

Through the menu: “restore and reset”.
By entering the number *2767*3855#.
Through Recovery Mod - you can call it by holding down “Home”, “Power” and volume down at the same time. Next, select the “Wipe data” section.

Conclusion

Issues with the functioning of Wi-Fi, as a rule, can be resolved easily and without the involvement of specialists. But it is worth remembering that independent technical intervention can damage the machine to the point of complete loss of functionality. If connection difficulties cannot be solved using available methods, it is better to contact a service center.

Video

I chose the title for this article not by chance. These are the questions that users often ask for help in the comments. As a rule, the problem occurs due to the fact that the router does not distribute the Internet over the Wi-Fi network and is associated with an incorrect connection of the client (computer, TV, tablet) to the network device. However, it also happens that there is a connection to the router, but there is no access to the Internet via Wi-Fi, and clients connected via a LAN cable to a network device have excellent access to the global network.

I think that many users, when this problem occurs, contact a service center or call a technician to their home. But if you don’t mind sorting out the problem yourself and at the same time saving N amount of money, then I propose to consider the main points related to the lack of connection and access to the Internet via the router’s wireless network.

No matter how trivial it may sound, the first thing we need to do is make sure that the Internet provider provides us with access to the global network and that everything is working properly at the moment. To do this, you need to insert the provider's network cable into the Ethernet port of the computer - bypassing the router. If you have access to the Internet, great; if not, then find out why your provider does not have access to the global network.

We made sure that the Internet works. Now we need to find out whether the problem is with the router or with the connecting client. To do this, for example, you can connect several devices (computer, tablet, smartphone) to the wireless network. If all devices find your wireless network, but when connecting to it there is no access to the Internet (websites do not load), then the problem is related to the configuration of the network device.

But if all devices connect safely and load sites and only one laptop, for example, receives the status without access to the Internet, then it is obvious that the problem is related to it. Earlier I described, and, so I will not dwell on these points, but below I will mention the problem with DNS servers.

The device does not connect to the Wi-Fi network.

If, when a client connects to Wi-Fi, the device does not see the wireless network, but connects to others without problems, then, as a rule, the solution to the problem lies in the settings of the router. Look at the top panel of the router in the indicator area and look for the LED that informs you about the activation status of the Wi-Fi module in the router. The indicator is located near the antenna with radio waves and if the module is turned on, the LED will blink or remain lit.

If the indicator does not light, this indicates that the module is deactivated. To turn on or turn off the Wi-Fi module in the router, you can use a special button located on the body of the network device, unless, of course, manufacturers have provided such an option.

But if there is no button, then you should go to the section responsible for the wireless connection (Wireless). As a rule, to enter the router interface you need to enter the gateway 192.168.1.1 or 192.168.0.1 in the browser line and log in.

This is how you can enable the Wi-Fi module in your TP-Link router:

And this is how activation is performed in an ASUS router:

Sometimes you cannot connect to a Wi-Fi network due to the assigned radio channel. Very often, users of this function assign automatic mode. Try changing, for example, to 1st or 6th. By the way, these are not intersecting channels. If, after changing the radio channel, the device (tablet, smartphone) finds the network, then most likely they are using a different region. In one of the publications, I already said that each region is assigned a certain number of channels. For the USA - 11; Europe and Russia - 13; Japan - 14.

It also happens that when connecting to a Wi-Fi network, the device crashes, accompanied by a message stating that the wrong password was entered. In this case, you can do the following one by one:

Set the encryption type to AES for the WPA2-PSK standard;
Enter a password consisting of only numbers (at least 8 characters);
Change the standard from WPA2-PSK to WPA-PSK.

The device connects to the Wi-Fi network, but does not access the Internet.

Sometimes it happens that the device is almost connected, but instead of accessing the Internet, we have to see the “Obtaining an IP address” message on the screen for some time, and then the connection is reconnected. If you encounter such a reconnect, then this indicates that the devices connected to the Wi-Fi router cannot obtain an IP address due to the fact that the DHCP server function is not enabled on the network device.

If, nevertheless, the DHCP server function is activated, and the router does not distribute the Internet via the Wi-Fi network, this may indicate problems with the DNS servers.
