Wi-Fi disappears on Windows, iOS, Android? Let's fix it! Why did the Internet stop working via the Wi-Fi router? Major router failures

Hello, friends! If you don’t know what to do if the router doesn’t provide wifi, or if the Internet through wi-fi often breaks, then you’ve come to the right place. It is difficult to unequivocally answer why this happens because there are many reasons and it will not be possible to give a specific “recipe” for all malfunctions.

Let’s try to take a closer look at the main reasons.

There is Internet, but the device connected via wi-fi does not open sites
Wi-Fi network drops frequently
Connection problems
Internet via wi-fi does not work

Let's start with the basics, a wi-fi network operates on a specific channel. When we set the settings in the router, we set this parameter to “Auto”. This value sets the automatic search and the device selects the appropriate channel to use. This is where problems sometimes lie, so let’s try changing the parameters.

Where can I change the channel settings?

To change the parameters you need to go to the settings of your router, you can read how to do this. Now I will show you using my Asus router as an example. Everyone has different routers, but the principle, the names of the menus where changes need to be made, are more or less the same.

Let's go to "Wireless Network" in English, it will be "Wireless". We need "Channel" or "Channel". We point at it and there will be a drop-down menu, you will most likely have “Auto” set. Now try changing channels from this list one by one, save the changes, reboot the router and test for functionality.

Often they create configuration problems with DNS servers. These settings are specified manually or set automatically. Sometimes the settings go wrong or the servers are unstable. Try setting the settings as in the image.

At least once in their life, every router owner has encountered its incorrect operation and wondered why this happens. For many, connecting via wireless WiFi networks is something vague and mysterious, so they think that if the router stops sending a signal, they should immediately call a specialist. In fact, there is nothing mysterious about the operation of the equipment. If you read this article, you will be able to understand all the nuances and cope with the errors that arise on your own. We will look at the most common problems why the router does not distribute WiFi.

Explain how to properly distribute the Internet using WiFi router We will use the example of a TP-Link router. All manufactured consumer models of home routers have similar characteristics, so once you understand how to configure one model, you can easily distribute the Internet from any other.

If the router stops sending a signal

When you observe a situation where a smartphone, computer or tablet has connected to the network, but the pages do not load, you need to find out the reason this phenomenon. There are several versions of why this happens: the router stopped sending a signal and the reason is that, or it’s a problem with the equipment or the Internet provider.

For this purpose, we first check the Internet directly, and not via WiFi. We connect the Internet cable to the PC and see if there is a connection. If there is no signal and the pages still do not load, then the problem is in the network and you need to contact your provider. If there is Internet, then we exclude one of the options for possible breakdown. We are left with two options: either the problem is in the device or in the router.

In order to check the problem in the device, try connecting several gadgets at the same time: laptop, tablet, smartphone, and so on. If all devices show WiFi connection and access, then the problem is with your device. If there is no Internet connection and the same problem occurs, it means that the router is not configured correctly, as a result of which it does not work correctly.

We found out why there is no Internet. Let's begin to resolve this issue.

Why does the Internet not work on a laptop?

If you find out why there is no Internet, and the reason is in the laptop, you need to check some settings:

First we connect the laptop to WiFi. In this case, a triangle will be displayed on the notification panel next to the WiFi symbol yellow color, which means there is no Internet.
Click this icon and go to the network control center.
Click on the line with adapter changes.
Select the wireless connection and open the properties tab. The picture below shows how it should look:

Open a window where we check the Internet protocol version (TCP/IPv4) and open the “properties” tab again.
Next, an additional context menu will appear in front of you. Here you need to mark the points, as indicated in the illustration below, and click “OK”:

Next, reboot the laptop.
We check WiFi, to do this we open an Internet browser and try to open any resource. After the settings, the sites should work correctly.

NOTE: a laptop or any other gadget can block the operation of the router due to antivirus software. Try temporarily disabling antivirus software when connecting to the router.

Attention! It is important to promptly update the laptop operating system, as well as the WiFi router settings.

Why did the router stop distributing WiFi?

Before you find out why the router is not functioning as it should, reset the settings to factory settings. Find the button on the back of the router and hold it for 10 seconds. Next, we proceed directly to the router itself, most of all we are interested in the “WAN” settings item. It is this section that is responsible for the connection, that is, for the operation of the Internet provider. If the provider uses a Dynamic IP connection, then you should have settings as shown in the illustration:

If your provider uses a different type of connection, then such settings will not work and in the very first step you will need to select a different type of settings, for example, Static IP, L2TP/Russian L2TP, and so on.

This problem can be solved very easily. All you have to do is contact your Internet provider and ask them about your connection type. By choosing the right connection type, you will find a solution to the question of why the router does not work.

This is what the router settings look like for an L2TP/Russian L2TP connection:

How to distribute WiFi if there is a connection to a MAC

Sometimes providers configure the connection to be bound to the MAC address, which negatively affects the functioning of the router. If you don't know if your connection has such a binding, then let's do the following:

First, connect your router directly to your PC via cable.

ATTENTION! The router must be connected directly via cable to the PC whose address is assigned to the Internet provider.

Select the “MAC Clone” tab in the router settings menu.
Click the line “Clone MAC Address”, and then select the item “Save”, or “Save”.
All that remains is to enjoy surfing the Internet and quickly exchanging information.

Also, if you are wondering why the router cannot distribute WiFi, you can try another effective method.

One of the most common problems owners have mobile computers– this is when the laptop does not connect to wifi and the wireless Internet has stopped working. Usually, the wireless network does not work after updating the software of a laptop or router, and often a fresh operating system that was recently installed on a PC does not see the Wi-Fi network.

The main thing in such a situation is to determine the reason why the laptop stopped functioning normally. And there are many reasons that sometimes even a highly qualified specialist does not immediately manage to correct the problem. Below is step-by-step instruction troubleshoot this problem.

Stage 1 – determining the cause

If there is no Wi-Fi network, then the reason does not always lie in the computer, but the most likely problem is with the Wi-Fi translator device. Due to this statistical fact At the first stage, it is recommended to check whether the router itself has stopped working.

To do this, you just need to turn on Wi-Fi on another device. If you can successfully catch the necessary networks and the gadget works normally on the Internet, then the reason is in the laptop. If the device does not see the required Wi-Fi, then the reason is in the router. Below are specific recommendations on what to do in each of these situations.

Stage 2 - turn on the Wi-Fi adapter in the computer

When identifying the cause in the PC, it is advisable to begin solving the problem by analyzing the current position of the adapter wireless network laptop, and if it is turned off, then you just need to turn it on and try to connect to the Wi-Fi network again.

Laptops are equipped with special lights that indicate the status of the wireless network and various methods to turn on WiFi. In the vast majority of cases, LEDs indicating the WiFi status are mounted on laptops on the front or side of the PC panel, but it happens that they are installed on the peripheral part of the display or inside the WiFi power key (in any case, manufacturers try to place the adapter indicator on visible part laptop).

The adapter is turned on in the following ways:

Method 1 involves simultaneously pressing “Fn” and the button with the Wi-Fi icon. In method 2 there is only one key, and in method 3 you need to turn it on by moving the switch slider.

If Wi-Fi does not work after completing the second step of the instructions, then you must continue to follow the instructions below and proceed to the next step.

Stage 3 – enable WiFi using OS tools

In addition to methods for activating the adapter using physical keys and switches, there are ways to enable WiFi through the OS on the computer.

For this purpose, the following algorithm of actions is required:

If for some reason the laptop cannot access the Internet, you need to start working with the instructions of the next step.

Stage 4 – debugging the wireless module software

It is necessary to analyze the performance of the Wi-Fi module drivers.

To do this, follow these steps:

Note: If the user’s device is not listed in the “Network Adapters” window, you will need to install drivers. Software usually comes on CD with your computer. They can also be downloaded from the official resource of the equipment manufacturer.

Stage 5 - if the reason is in the router

Actually initial stage The instructions analyzed why Wi-Fi stopped working on a PC and the most likely course of action to troubleshoot network problems. But, since today there are a huge number of brands of routers and no less number of firmware for routers, therefore on at this stage You will have to limit yourself to only generalized wishes for debugging the device.

So, when, in addition to the laptop, another gadget also does not see the network, then the cause of the problem is probably in the router. Below is a list of actions that the user should take in such a situation:

Reducing the distance between the laptop and the router may help. It is recommended that you experiment with the placement of your devices and enable your wireless network. Often positive result may appear after removing obstacles such as large furniture and Appliances, microwave ovens, interior ceilings. When there is no signal even with line of sight, then proceed to the next step;
Determine whether the Wi-Fi light on the router is lit;
Enter the router settings, where you analyze the following points:

A) is the Wi-Fi module turned on;

B) is the SSID enabled;

C) whether the MAC of the laptop is included in the list of ignored ones.

This is the entire list of problems when Wi-Fi does not work and there is no way to turn it on on the computer. Each individual case has its own nuances, for example, perhaps the Internet has stopped working and the laptop does not see the required router due to the banal reason of a device cable break, etc., but this is a topic for a separate publication.

It happens quite often that Wi-Fi does not work on a TP Link router, but this can also happen with routers from other companies. Now we will find out what to do in such a situation.

Fixing the problem

First you need to decide:

The router is turned on, but there is no WiFi network at all, that is, the device does not distribute anything;
The router is turned on, WiFi is available, but there is no Internet.

It is based on specific conditions that you need to choose a way to solve the problem. Everything that will be described here is suitable for the following models of TP-Link routers: TL-WR741N, TL-WR841N, TL-WR1043ND and so on.

Network name

Many people buy the same device models and when they create an access point, they do not change its name. This is where confusion occurs and you cannot find your network, thinking that it does not exist at all. In this case, turn on the search for networks, for example, on your phone, then turn off the Wi-Fi distributor and see which network disappears, that was yours.

The router is not working correctly

Alternatively, you can reset the router settings or reboot it, but it’s better to start with the second one, if it doesn’t help, then reset it. To reboot, simply unplug the cord from the outlet and plug it back in, and to reset the settings, there is a special button on the back of the device. Then double-check whether there is Internet or not.

Router is turned off

You need to check, maybe you didn’t turn on the router at all, that’s why the TP Link Wi-Fi router doesn’t work, and if it’s plugged into the socket, but the power indicator doesn’t light up, then you should press the ON/OFF button, it can also be found on back side router where the wires are connected.

Wi-Fi network is disabled

Another reason why the Internet distributor does not distribute the network. There is a small button on it that turns Wi-Fi on/off, press it.

A WiFi icon or inscription will be drawn next to it.

Router settings

What to do if your TP Link Wi-Fi router stops working? Sometimes the reason lies in incorrect settings; to check them, enter 192.168.1.1 or 192.168.0.1 into the browser address bar and click Enter.

You will be taken to the login page. Enter your username and password - admin admin.

We are interested in the section "Wireless Mode", which can be found in the menu on the left.

Open it and check that the checkboxes are as shown on the screenshot.

That's all the setup.

Conclusion

Here are all the ways to solve this problem. If all else fails, your router may be broken and should be taken to a service center.

When working with a PC, laptop, tablet and other devices, users sometimes encounter the following problem: the router does not provide Wi-Fi, but the Internet is available on the computer. To correct the problem, you will need to perform several simple manipulations, using the recommended methods designed to debug the system’s performance and achieve desired result. Let's look at the main situations when the router stops distributing wi-fi.

In addition to a computer or laptop, other devices are connected to the Wi-Fi network: tablet, smartphone, TV, etc. They all work on different systems, but they face the problem that the gadgets are not able to connect to the wireless network.

In order to fix this problem, you must first reboot the router and then try to connect again. If this method does not help, you need to re-create the wireless connection on the network device itself. The wi-fi network name must contain only Latin characters. You can also try changing the password and then reconnecting to the wireless network so that the router is able to distribute the Internet.

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

Often the problem when the router cannot distribute Wi-Fi arises due to failures in the device settings: for example, time/date desynchronization. In addition, it is possible to reconnect the personal network again. Sometimes resetting the settings to factory settings on the device connected to the Internet, as well as on the router, helps.

The cable is damaged or incorrectly connected

Often the problem when the router has stopped distributing wifi, but the Internet is working, is due to mechanical damage to the Internet cable or its incorrect connection.

First of all, you need to check whether the Internet cable is connected correctly. It should fit into the WAN connector of the router, marked in blue. You should also make sure that the appropriate cable is also connected to one of the yellow LAN ports (directly for the computer’s network card).

The indicators on the router do not just light up, but, as a rule, signal that the Internet is connected, as well as the use of one of the ports. When network cables are correctly and securely connected, but the indicators do not light up, the insulation condition should be checked for mechanical damage: breaks, bends, etc. If there are such problems, the router, of course, is not capable of distributing the network.

Problems with the router

There are also options when there is Internet on the network equipment, but the router does not distribute the Internet via wifi. The causes of the problem are different, often associated with incorrect operation of the router itself. Some users believe that if the router stops distributing the Internet, the device stops working. However, it is worth debugging the settings of the adapter, as well as the computer itself.

Signs that indicate a router malfunction:

The laptop or computer does not detect the Wi-Fi network.
The connection is unstable. There are constant connection breaks and reconnections.
The modem provides extremely slow speed.
The device is connected to Wi-Fi and the router is working, but there is no access to the global network.

Thus, before replacing your router, which is unable to distribute the network, you should check and reconfigure it. The solution to the problem when the router for some reason does not distribute Wi-Fi, but the Internet is on the computer, is carried out not only by programs, but also by hardware testing.

If the wireless connection is not established, then the problem is in the wifi settings on the router. But if other devices work stably, the problem lies in the equipment making useless attempts to connect via wifi.

Each router has a special button that is responsible for turning the device on and off; using it, the router reboots. In order to check its physical health, you should press the button and make sure that the indicator with the Wi-Fi icon on the case lights up. If this happens, the router is technically sound and in all likelihood is capable of distributing the network.

There are a great many reasons for software problems when the router does not distribute the Internet via wifi, ranging from the features and settings of the network card to blocking Wi-Fi connections antivirus. Among the most common problems are errors in the configuration settings of the operating system. This is especially true in cases where the computer was previously connected to another provider. To check or reconfigure on Windows 7 you will need to take the following steps:

Open Network and Sharing Center.
Click on the “Change adapter settings” button.
Click on “Wireless Connection Properties”.
Next, a small window will open where you should find the line “TCP/IPv4 protocol” and go to its properties.
The above manipulations will open the network card settings. Here, opposite the corresponding lines, you should enter your own IP address, gateway and DNS server addresses, if known. Sometimes it is recommended to set markers on automatic address retrieval functions.
After entering and confirming all changes, restart the computer. Internet setup is complete.

If the above manipulations do not have the expected effect, you need to dive directly into the interface of the router itself. This is necessary in order to change the address in the wireless adapter settings.

To do this you need to do the following:

This manipulation is performed in order to prevent the simultaneous operation of several routers, for example, among neighbors when operating in single channel mode. This channel related issue is quite common. For greater efficiency, it is recommended to try and compare the work on each channel.

In addition, you need to check whether the Wi-Fi distribution function is enabled on a specific router in its settings.

If the router's wireless network settings section does not contain a checkbox next to Enable Wireless Router Radio, it must be checked in order for the router to be able to distribute the network. In some situations, it may be wise to perform a factory reset and then completely reconfigure everything. To do this, you need to press and hold the button on the router for at least ten seconds.

Connected device problems

Computers and laptops sometimes have erroneous network settings using incorrect addresses or parameters, which should be double-checked before connecting gadgets to the Internet. In addition, some antiviruses and other security programs can block connections and access to the Internet. In some situations, it is recommended to reinstall the wireless device driver.
Devices with different systems have different parameters, so often the problem when a router stops distributing Wi-Fi is not only a matter of connection settings.

Conclusion

This article discusses the situation when a working router for some reason stopped distributing wi fi (device network), and provides recommendations for troubleshooting a similar problem when the router works but does not distribute the Internet.
