The router does not connect to the Internet, TP-Link does not see the network

It happens that the router fails to cope with its main task - to provide the opportunity for different devices to connect to the Internet. These are computers, smartphones, laptops, tablets, any devices connected to it via a network cable or via Wi-Fi.

The fact that the router does not distribute Wi-Fi can manifest itself in different ways. Sometimes the network disappears. Or all devices see it, but the pages do not load. You either see a completely white screen in front of you, or a message that the network is unavailable.

To resolve these issues, pay attention to the router as well as the network settings. Let's consider the sequence that should be followed and what to do when the router does not distribute the Internet, step by step.

A router is a special network equipment, thanks to which the user has the opportunity to distribute the Internet to many home devices. You can find and purchase various models of routers on sale. Products from the brands Asus and TP-Link are popular. Many providers, for example, Rostelecom, offer to rent such equipment or purchase it in installments. If a twisted pair cable is installed in a private house or city apartment, through which the user gains access to the Internet in the cottage, it can be connected directly to a computer or laptop, or use a router. But what should the user do if the Internet status is disabled and the router does not see the network? Below we will talk about why such errors occur, and also consider in detail the main problems with the TP-Link router.

Causes of router malfunction

Wi-Fi Internet “tightly surrounds” our daily life: it is present in many offices, shops, various cafes and, of course, what would it be like at home without Wi-Fi. This is facilitated by a huge selection of routers and their low price. Anyone can easily buy a router and enjoy Wi-Fi Internet anywhere in their apartment.

The more routers, the more problems associated with them. After some time of flawless operation of the device, suddenly the Internet disappears, the question immediately arises - why the router does not work. So I would like to talk about problems that appear unexpectedly.

All problems in the operation of the router can be divided into two categories: software problems (the firmware has crashed, problems in the operation of your OS, etc.) and hardware problems (failures of the router hardware itself). Let's look at the most common problems that can happen with a router.

Why the router does not connect to the Internet: typical problems

When the router does not connect to the Internet, there can be many reasons for this.

Below we will look at the main causes of problems with Internet connection, including the TP-Link router:

Often there is no internet connection on TP-Link due to the ISP. If the problem is on the service provider's side, you can perform this check. You need to connect the cable directly to your computer or laptop. If access to the network still does not appear, then the problem is on the provider’s side. All the user can do in this situation is call customer support.
No cable connection. In TP-Link routers, the cable must be connected to the connector that is marked “WAN” (usually highlighted in blue). Visually similar “LAN” connectors are used to connect additional devices.
The operating parameters of the router are incorrectly configured. This is a fairly common reason for the lack of Internet on a router. The most accurate information for settings can be obtained from the provider. If after setting up the router yourself there is no Internet, you can always contact a technician or reset the settings to factory settings.
Physical malfunction of the device. If the router is damaged and cannot work, it must be taken to a service center for repairs.
Software failure in the router. The situation can most often be corrected by rebooting. If you have rebooted your device but the problem persists, you can try a factory reset.

The Internet can disappear for various reasons. If you cannot find and fix problems yourself, it is better to contact technical support.

Purpose of router indicators

And finally, let’s look at what the indicators on the top panel of the router show.

First indicator. – Power

(power indicator) – shows whether the router is on or off.

Second indicator – System

(system indicator) - in normal condition it blinks, if it is just lit - the route is being initialized or an error has occurred, if it is not lit - then a system error has occurred.

Third indicator - shows the status of the Wi-Fi network

. Flashes when wi-fi is on and off when it's off.

Indicators 4 to 7 – show the status of the local network connection

. On – the cable is connected, but there is no network activity, Flashing – data exchange between the router and PC, Off – no connection.

Eighth indicator – Internet

– shows whether the Internet connection is active. On – the Internet is connected, Flashing – a connection or data exchange is in progress, Off – the Internet cable is not connected.

The last indicator shows the status of the QSS

(Quick secure setup). This function is used to quickly connect devices to the router. It is mainly used to connect TP-LINK wi-fi cards to the router.

Checking the correctness of the router settings

Different models of TP-Link devices may have several Internet connection sources.

Eg:

cable connection;
USB modem;
Wi-Fi.

Therefore, you need to select the correct source in the settings. To go into the router settings, you need to first connect to it. You can use a cable (the best way) and use it to connect the router to a PC or laptop. Please note that in this case the LAN connector will be used. We launch any web browser installed on your computer or phone. In the address bar we enter the device address: 192.168.1.1 and confirm the transition.

For routers of other brands, the address may be different. You can find out the exact IP on the label that is attached to each router. There you can also check the serial number of the device, password and login for logging into the web interface. When the welcome window opens in front of you, you will need to enter your login and password. In TP-Link models, the default values are admin. It is advisable to change the default values to prevent unauthorized access to the control panel of the device.

Next, after you get to the main menu, you need to select the “Network” category. Then we find and select the “WAN” subsection, the next step is to click “Dynamic IP”. When you enter new correct settings, do not forget to save your completed actions by clicking on the “Save” button. Otherwise, the new settings will not take effect. If there is “Internet”, you will need to indicate the source here. Usually it is enough to select WAN. This is the connected cable that you previously installed in the WAN connector. In some cases, users can also choose not a “Dynamic IP” connection, but a PPPoE connection. But then the subscriber will need to enter a login and password. These values are provided in the contract for the provision of information about connection autotesting. If you find Disable, it means that there is no Internet at the input. In other words, the signal is not coming from the Internet service provider.

WAN is broken or the Internet is only on the computer

The main reason why this problem occurs with a WiFi router is the connected WAN connection on the computer. The point of setting up and operating a wireless router is that it will establish a connection to the Internet on its own, and then “distribute” access to other devices. Thus, if the router is already configured, but the Beeline, Rostelecom, etc. connection available on the computer is in the “connected” state, then the Internet will only work on the computer, and the router will take virtually no part in this. In addition, the router will not be able to connect the WAN, since it is already connected on your computer, and most providers only allow one connection from one user at a time. I don’t know how clearly I was able to explain the logic, but even if it’s not clear, just take it for granted: for everything to work, a separate provider connection on your computer must be disabled. Only a local network connection should be connected, or, in the case of a laptop, etc., a wireless network connection.

Resetting the parameters

If you cannot connect to a TP-Link router or a device from another manufacturer at all, or you cannot enter the control panel through the address bar, you can try resetting the settings to factory settings.

The sequence of actions will be as follows:

We disconnect all wires from the router, leaving only the power.
Armed with a thin object, press the reset button and hold it for about ten seconds.
The router will reboot itself, notifying the user about this with a light indication.

The configuration settings will be reset. You can then reconnect to the device and configure it. The same algorithm will apply if the user has forgotten the password for the wireless home network. If the user resets the router settings, and there is still no Internet, the device immediately turns off - this is a reason to contact the service center technicians. Typically this type of hardware behavior indicates a hardware failure. Try replacing the router and reconnecting to the Internet. If network access has resumed, the problem is clearly a faulty device.

TP-Link routers are the best option for distributing the Internet. They are extremely easy to install and configure, and are convenient to use.

Troubleshooting TP-Link router

Hello friends! Wi-Fi Internet is no surprise to anyone now; it is available in almost every office, store, cafe and is actively appearing in homes. A large selection of routers and their low price 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 question of setting up, connecting, breaking, etc. of these same routers has become relevant. If I have already written a lot of articles on connection, settings and various errors, which you can read in the category “Internet, Wi-Fi, local networks“, then today I want to talk about the most popular failures of Wi-Fi routers and give some tips that will help you fix the device, or simply determine the cause.

There are a lot of comments left on this site about various problems with routers. And very often the cause of some error is not the settings (as many people think), but rather technical problems in the router itself (in the hardware).

Today I want to talk about problems that appear unexpectedly. Like this? Well, the router worked great, distributed Wi-Fi, made everyone happy :), and then it stopped working. It doesn’t matter how it stopped working completely, or simply not how it should work. The main thing is that it used to work well and stopped working on its own (you did not change any settings).

It’s just that the problems that appear during the first setup of the router most likely arise due to incorrect settings.

How to solve the problem “Unidentified network without Internet access”

Users often encounter this problem when a notification appears on the computer screen that the network is not recognized and there is no Internet. This type of problem occurs for various reasons. Below we will look at what actions need to be taken to restore operation. Often this phenomenon occurs if the computer owner configures access to the Internet or router, and suddenly everything is reset. Usually in such situations, users blame the provider or PC.

The problem can be recognized by the following symptoms:

There is no Internet on the computer.
Web pages load at slow speed.
At the bottom right of the screen, an icon is displayed - a yellow exclamation point on a yellow background.

There can be quite a few reasons for this problem, most of them can be eliminated on your own in a couple of minutes.

There is no Internet connection on the router

It happens that you turned on the router, but it is not connected to the Internet. It's very easy to find out about this. Your device will not see the network, it will disappear. First you should turn off the router. Wait 2-3 minutes and turn on the power again.

Remember that a number of models from TP-Link, Keenetic, Zyxel are equipped with a separate button that turns Wi-Fi on and off. Perhaps it was simply pressed, which caused the problem.

You can make sure everything is working by looking at the status of the Internet LED indicator on the back of the router. When everything is normal it should flash. If the device does not have access to the Internet, it simply lights up steadily or does not light up at all.

Sometimes the problem is in the PC, laptop or smartphone itself. For example, if you have an iPhone, find the selected channel in the Wi-Fi settings of the “Home Network” segment. It may turn out that it was chosen incorrectly. You should find a free channel and activate it.

Leave a request and our specialists will promptly resolve your issue

The network may disappear if the WAN settings, that is, the connection to your provider, are incorrect. You need to reset the router settings and configure it again, enter the data provided by the provider. If the connection type (static, dynamic IP, PPPoE, etc.) is correct, the router should establish a connection.

It is very rare, but there is a situation that the router does not distribute Wi-Fi when the wireless module is turned off in the settings. When setting up your device, go to “Wireless Settings” and make sure that “Wi-Fi Communication Status” is in the “On” position.

If you are sure that you did everything correctly, but there is still no connection, the reason may lie in a hardware error.

Why does the notification appear?

To understand what the origin of the problem is, it is worth checking and determining whether other gadgets can work through the router. If the home network on another computer or laptop works correctly, this means that the problem is not with the service provider.

Otherwise, there are two options:

The “No Internet access” notification appears, but the unidentified network is not in the list of connections;
The notification is displayed in full.

In the first case, the problem is related to equipment or a failure on the provider's line. And the second option indicates that there are problems with the router.

If you have determined that the problem is due to internal problems, you must proceed as follows:

Restart the PC that displayed the error notification.
We reboot the router: disconnect it from the power supply, wait about ten seconds and connect it again.

Please note: the device may stop working after updating the operating system. Another likely reason is the installation of a new antivirus program. Try deactivating the security program for a while, and then reactivating it again.

Below we will look in detail at the reasons why a notification about an unidentified network without Internet access most often appears.

Lack of response to power supply

You connect your router to the power grid, and in response there is silence: not a single indicator lights up, nothing blinks. Everything is very bad, apparently your router has completely failed.

What to do?

First, look at the power off button; sometimes when it is pressed involuntarily, it turns off.

If it is on, check the power supply. Basically, the power supply “burns out” much more often than the router itself. The functionality of the power supply can be checked with a special device (for example, a “tester”), or if you don’t understand this, then by connecting a known-good unit (you can borrow it from a friend or neighbors).

Incorrect IPv4 values

To correct the situation, you must perform the following steps:

launch the Start menu;
find the “Control Panel” section;
here we will be interested in the subsection “Network Control Center ...”;
find and select “Change adapter settings”;
We find our unidentified network in the list of connections and click on it with the mouse;
then select the “Properties” submenu;
here you need to go to the subsection “Internet Protocol version 4 TCP/IPv4”;
select the “Properties” menu again;
We check the status of auto-obtaining IP and DNS. Must be active.

In addition, you can change the IP type. Change the last digit. It would also be a good idea to clear your DNS cache. After making changes, the new settings must be saved. If this was the reason for the failure, the problem should go away and you will have internet access back.

Ways to fix the problem

There are several ways to resolve the problem of missing Internet, depending on the specific circumstances. Everything discussed below can be done independently.

Incorrect Wi-Fi settings

Incorrect router settings are most often indicated by a lit but not blinking Wi-Fi indicator, as well as a change in its color from green to orange or red. The problem is resolved by correctly configuring the network settings. This procedure is somewhat different in different router models, although the principles are the same. If you have never configured routers before, it is best to entrust this task to a specialist called to your home; at a minimum, you can check whether the wireless network is enabled in the device settings.

To enter the router settings, connect it to your PC via cable, go to 192.168.1.0 or 192.168.1.1 in any browser and log in with your login/password (admin/admin by default). In TP-Link routers, for example, you need to go to the “Wireless” section and check whether the “Enable Wireless Router Radio” item is checked. The checkbox “Enable SSID broadcasting” must also be checked, otherwise devices will not be able to see the network. In other models, the setting may be located in a different place (look for the Wireless network or WLAN section).

A very interesting case is when a laptop sees the network, but a smartphone or tablet does not. It turns out that the router does not distribute the Internet via Wi-Fi only to mobile devices. Owners of smartphones and tablets brought from the United States sometimes have to face this problem. The reason for this is the discrepancy between the channel selected in the router settings and the settings specified in the firmware of the mobile device. The problem is usually solved by manually selecting the channel, 1st or 6th.

Incorrect IPv4 parameters

This problem is usually caused by malware, which causes the network address to change. As a result, the PC or laptop cannot access the Internet. To correct the situation, you should use the following algorithm:

Go to the “Control Panel” (via the “Start” menu).
Next, “Network and Sharing Center...”, where you can find the line “Changing adapter settings.”
In the list of connections, find an unidentified network, right-click on it (RMB) and select “Properties” from the drop-down menu.
Select “Internet Protocol Version 4 TCP/IPv4” and click on the “Properties” button (it’s a little lower and to the right).
Make sure that the IP and DNS server addresses were selected automatically. Only this does not apply to the corporate network.

To solve the problem of why the router does not connect to the Internet, it makes sense to change the IP type, change the last digit, and also clear the DNS cache. The changes you make must be saved, otherwise they will not take effect. After this, the problem will disappear, provided that this particular failure was the cause.

Important! If the reason for the lack of Internet is a hardware failure, then the problem can only be resolved by contacting a service center.

Problems with TCP/IP

The problem lies in a software malfunction. It is recommended to reset TCP/IP settings. This is done like this:

The command line is launched, and as an administrator through the Start menu.
In the black window that opens, enter: netsh int ip reset resetlog.txt, then confirm the action by pressing the Enter key.

Or you can enter three commands in sequence:

Netsh int ip reset.
Ipconfig/release.
Ipconfig /renew.

Executing these commands involves rewriting system registry keys. And for them to take effect, you must restart your computer (laptop) after completing the procedure.

Fixing the problem via the command line

Temporary failure of the router

If the router works day and night, its operation may sooner or later fail, so the very first thing to do if the router stops distributing the Internet is to turn it off, wait a few minutes, and then turn it on again.

Rebooting the router can also help the device (computer or tablet) detect the network if it is suddenly not detected when the device is turned on. Users of devices connected to one or another wireless network often encounter this problem.

Many clients

If the Internet is slow (for example, the router connects to the network via a wireless modem), or when there are many clients on the network that occupy the entire channel, it makes sense to check the number of connected devices. The access point needs to be protected with a password if the traffic is not encrypted, or replaced in case the neighbors find out.

The processor of an old router may not be able to cope with heavy loads, causing it to heat up and freeze.

Visit your hardware settings through your browser.
In the “Wireless Mode” section, click on the last item.

Here you can see a lot of useful information: the number of connected devices, their MAC addresses and activity, and act according to the situation:

block unnecessary clients by MAC address if they are not familiar to you (it’s easy to identify other people’s devices by disconnecting and connecting your own one by one, but that’s a separate topic);
limit the speed for the most active ones, for example, neighbors who have been given a password - determine the MAC of such devices, assign them a static IP within the network and reduce the speed in the “DHCP” section;
set/change a password to protect the access point - anyone can connect to an unsecured network, and one neighbor can share connection data with others.

Torrent clients can significantly increase the number of connections. In the settings of such programs, their number is limited.

Router location

The location of the router plays a big role in the direction of signal propagation and its range. An electromagnetic wave propagates in space in the form of toroidal waves - tori (donut), and not a sphere, as many people believe. The location of the antenna determines the coverage area of the Wi-Fi signal.

When the antenna is positioned horizontally, the signal will spread throughout the house or apartment evenly, and:

strictly under and above the router it will be the weakest, in the immediate vicinity it may be completely absent;
on the floor above and below, the network level will noticeably decrease.

The second point is that the router needs to be replaced at an equal distance from all clients (in the center of the apartment).

The third is obstacles. Every door, cabinet, wall (especially concrete/stone) with metal structures (profiles, fittings) is an obstacle to an electromagnetic wave. Try to position the router so that there are a minimum of obstacles between it and the device.

Newer routers allow you to control the transmitter power. If the problem is caused by a weak signal (it is lost, then detected again, low speed), try increasing it, but you may not get a noticeable effect - only the transmitter power of the router increases, but not of the smartphone or laptop.

Physical damage

Very often, users are faced with the problem of lack of Internet, without even realizing that the reason for this phenomenon lies in the malfunction of individual elements. For example, a damaged cable or a loose connector often causes a lack of access to the network. Do not forget that if the wires are deformed or damaged, the Internet will not work. Check the integrity of the cable, whether there are any breaks or kinks. Check the plugs to ensure they are inserted tightly enough to work correctly.

Why the Internet does not work: other reasons

Below we will take a closer look at other factors that could also lead to the loss of Internet connection:

Zero or negative balance. The first thing to do if the Internet is lost is to check your account. Perhaps you forgot to replenish it in a timely manner and therefore were left without the Internet.
Technical work on the line. Call the provider's support service and find out if maintenance work is being carried out on the line. Typically, service providers notify their clients about scheduled work on the official website.
The network adapter was accidentally disabled. In the Network and Internet section, you need to check whether the network adapter is active. If it is disabled, it needs to be activated.
The operating system is infected with viruses. There is malware that can block access to the Internet. Install a reliable antivirus program and run a comprehensive scan.
Firewall action. Special computer OS applications can automatically block access to the Internet. Try disabling the firewall for a while and connecting to the network.

We looked at the main reasons for lack of access to the Internet. If you are unable to resolve the problem yourself, you should use the help of a wizard.

Is your computer terribly slow?

Many people are familiar with the annoying situation when the operating system slows down and slows down, sometimes so much that it loses important data due to the impossibility of saving it. There are ways to get rid of these problems, but it is better not to fall into them.

Helpful steps in this case:

Scan your computer for viruses. If your PC is constantly slowing down, it most likely contains malware, adware, or a virus. A scan will identify the problem and usually fix it.
Get rid of unused programs. It is better to remove unnecessary software along with registry entries that can slow down your computer.
Clear the registry. This can have a big effect, and it is better to do the cleaning using specialized software, because... Manual cleaning requires special knowledge.
Defragment your hard drive. This will allow you to collect files “scattered” on the disk, which will speed up the OS access to them.
Don't multitask too much. The user can be productive when working with only a few programs, and the likelihood of the PC slowing down will be significantly reduced.
Update equipment. Computers on average are designed to last up to 5 years, as technology develops very quickly.
Reinstall the operating system. This is an extreme measure, but sometimes the only one that brings back the “fast old” PC.

As you can see, all that usually needs to be done if the computer “slows down and freezes” is to give it a little attention from time to time, which only takes a few minutes.
