What to do if wifi doesn’t work. Problems with Wi-Fi and wireless home Internet

A huge number of people use it. It is both convenient and very easy. But no matter how simple the connection through this type connection, situations are still possible when WiFi does not work. And in order to restore the network, it is necessary to find the causes of the problems, which will be discussed.

Doesn't work WiFi due to the fault of the transmitter

A transmitter can be called a WiFi device to which other devices are connected - a WiFi modem, a WiFi access point, etc. Naturally, if this equipment stops broadcasting, then the end devices will also not work.

It is easy to determine the functionality of the WiFi transmitter - you need to go to the section where your equipment connects to the network. Both on phones, tablets, smartphones, and on any modern computers that support such a connection, this section should display the name of your WiFi network. This will make it clear whether your transmitter is working.

However, situations often occur that there may be several networks in the area. How do you know if yours is on the list? It’s very easy - just turn off the equipment and update the list - if one of the names disappears, it means it was your network. Now turn on the WiFi transmitter and update the list again. If a new name appears, it means this is your network.

So we figured out whether your device broadcasts radio. But if when you click on the inscription, a connection occurs, but WiFi does not work (still), what should you do? This is a completely different question. Now we understand for sure that the WiFi network actually works, but if there is no Internet, this is already a matter of the settings of the transmitter itself (if the problem is its fault). The following situations may be to blame:

The WiFi transmitter is not configured or configured incorrectly.
The Internet is completely blocked on your device by viruses, antivirus, a non-working Proxy server, or an Internet provider (for technical reasons).
You need to pay for internet.

To eliminate some of the above problems, a comprehensive check is required, which not everyone can carry out, but a call to the office of the Internet provider is enough to get started.

Doesn't work WiFi due to the fault of the end device

Very often, the reason for the inoperability of a WiFi network is the user himself or his equipment. If WiFi does not work on the end device, then you should pay attention to the following:

Unfortunately, it is impossible to give all the reasons within one article. But in order for an ordinary user to find out why WiFi does not work, this fundamental knowledge is enough, which should give the reader basic concepts from which to build on in the future.

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 settings. Enter the address in the browser or 192.168.1.1 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 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 (this was done by the technician when connecting to the Internet) or a cable from the ADSL modem. The figure shows how to properly 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.

You can obtain information about your connection type from your Internet service provider. In addition, if necessary, he should give you a login, password, and IP address. Some connection types do not require this. Detailed information you can get information about this here .

We have looked at all the reasons why Tp-Link routers will not distribute a Wi-Fi network. We hope that you have successfully resolved all the problems and now the router is working correctly. If you have any questions, you can ask them in the comments to the article.

If you purchased a laptop, you probably expected that you would use it to access the Internet. However, if your wifi does not work on your laptop, then you will not be able to connect to the network wirelessly. Therefore, if such a problem occurs, it is better to know in advance how to behave in order to quickly resolve the problem.

Checking the router

Before you begin to figure out why Wi-Fi is not working, you need to determine the source of the problem. Try connecting to the wireless network through any other device - smartphone, tablet, game console. If a connection is established on another device, then it is the laptop that has stopped working correctly.

If no device connects to the wireless network, then the cause of the problem should be looked for in the router. First, try to shorten the distance and remove all obstacles between the router and the laptop. Check that the wireless light on the router is on. If the light does not light, check your Wi-Fi settings:

What should I do if the above steps did not help, and the wireless connection still cannot be established or is slow? Call your provider to check if there are any problems on their end. If the operator reports that everything is fine, reset the router settings to factory settings, and then re-establish the connection, having first updated the router firmware.

Laptop problems

If you are convinced that the router is working normally, but there are no connections available on the laptop, then you should check whether the wifi module is turned on on the laptop. If the module is turned on, the indicator on the front panel of the laptop should light up. If it doesn't work, try turning on the Wi-Fi module manually using the function keys - e.g. Fn+F2. On different models The keyboard shortcut is different; Some models have a hardware wifi button. Carefully inspect the laptop case and find the button with the image Wi-Fi signal– click on it to turn on the adapter.

If the Fn button does not work, you can turn on the module using the switch found in the wireless connection settings. On Windows 10, you will need the Network and Internet section, which has a Wi-Fi tab.

If Windows 7 is installed on the laptop, then this method will not work. In this case, you will have to use an external keyboard with the Fn button (or the Windows on-screen keyboard).

Internet settings are reset after reinstalling Windows. If problems arise after installing the system, then you definitely need to check the adapter operating parameters. In addition to hardware enablement of the module, it is necessary to activate it in the system. On all versions of Windows, software activation is carried out according to the same scheme:

If there is no wireless connection or it does not turn on, then you need to check whether the Wi-FI module driver is installed correctly. If the driver is not installed or does not work well, you will not be able to connect to the wireless network.

Checking the Wi-Fi driver

On all laptops, be it Lenovo, HP or any other brand, the Wi-Fi module should appear in the device manager, even if the driver is not installed correctly. To check the wireless module driver, you need to open Device Manager:

Right-click on the “Computer” icon.
Open the Manage tool.
Select "Device Manager" on the left.

In the manager window, you need to open the “Network adapters” section and find the Wi-Fi adapter. There should be no warning signs near it. The properties should indicate that the device is working normally. If everything is installed correctly, but the Internet does not work, you need to try updating the driver.

To avoid compatibility issues, you need to know your laptop model. Armed with this information, go to the manufacturer’s website and download the Wi-Fi adapter software in the “Drivers” section.

Problem with drivers for network devices

Testing the WiFi module driver is carried out in the “Device Manager”. This section is located in the Start menu. You can also get to the section through the “My Computer” shortcut by clicking the right mouse button.

In the "Manager" you can see all the devices connected to the computer. We will be interested in network equipment. You need to switch to the branch with network drivers. If the branch is missing, this means that the drivers for the wifi adapter were not installed on the computer.

If there is a branch, the “!” sign may light up on one of the network devices. This means either the absence or malfunction of one of the drivers. Each of the problems is easily solved by simply reinstalling the software. Typically the software is located on the disk that came with your computer. The wifi adapter for device manager may be called Wireless Network Adapter. Also, everything you need can be downloaded from the Internet using a mobile connection (if another is not available at the moment).

How to check your wireless connection status

If everything is fine with the drivers, then the next step is to check the wireless connection. It can simply be turned off. On different operating systems testing is carried out in different ways. But it all comes down to one thing: you need to get into the “Network Control Center”.

There is a universal method. You need to press Win+R, after which a window with a line will appear. In the line you need to type the command control panel and press Enter. This will open the "Control Panel". Here we go to “Network and Internet”, then to “Network and Sharing Center”. In the “Center” we will be interested in the “Change adapter settings” section located on the left. Clicking there will allow you to see the status of all connections that are available on the computer.

“Wireless connectivity” is what will be important to us. If the label is not colored but gray, it means there is no signal. You can start the connection by double-clicking the left mouse button. After startup, the computer begins to search for all available connections.

If they do not appear, then you can try to perform system diagnostics. It is carried out through the “Network Center” and the “Change adapter settings” item. You need to right-click on the “Wireless Connection” shortcut. In the window that opens, click the “Diagnostics” field. The computer runs the test on its own. Based on the result of the check, the user receives advice on further actions.

What to do if a hardware error occurs

A hardware error would indicate a problem directly within the network card. In a word, if the computer does not see the adapter for connecting to Wi-Fi, it means that this Wi-Fi device is not functioning. There are two main reasons:

the device is broken;

There was a problem with the wifi drivers.

The second option has already been described by us. However, if Wi-Fi drivers are available, but the computer continues not to see the adapter, this means a breakdown. One of the most common causes of breakdown is device combustion.

The cause of combustion may be overheating if the computer for a long time works at the maximum level of its capabilities. If we are dealing with a laptop, then this happens even more often, since many users forget the device on a soft surface that blocks access to the hole through which air flows for cooling. This problem can be solved by simply replacing components with similar ones.

It is worth keeping in mind that a lack of experience in independently manipulating computers can lead to even more detrimental consequences. This is especially true for laptops that have more complex design. The best way out In any case, you will need to contact the service center, where they will accurately determine the reason why the device does not work.
Hardware connection errors also include a disconnected antenna. Most often, this problem occurs in laptops or desktop computers that have been cleaned or repaired in some way. The specialist performing the procedure could simply have forgotten to connect the device, or he connected it incorrectly. This makes it impossible for the adapter to function normally, as it does not work normally and cannot normally catch the signal distributed by the router, even if it is close to the source.

A rather rare case is the antenna terminals becoming clogged with dust. This breaks internal contact. The solution to the problem is cleaning.

Why does the Wi-Fi router not distribute the Internet?

The connection problems described above relate to malfunctions in the computers themselves. But often there are problems that are related to the way the router works (or, more precisely, rather does not work) and does not distribute the Internet.

There are two main problems:

inability to establish a wireless connection;

lack of access when connected.

The listed failures can be easily resolved independently, without resorting to the services of specialists.

How to solve wireless connection problem

Testing how the router works begins by checking the status of the indicators that are located on the external panel of the router. During normal operation, the LED near the antenna pattern will remain lit or flashing. If there is no light at all, this means that the wireless module is not running on the router. On certain models there is a separate button that can be accidentally turned off by one of the family members.

The lack of a button makes solving the problem a little more difficult. You need to go to the “Wireless Network” section located in the router’s web interface. In the English menu this section is called “Wireless”. There is a checkmark next to the “Enable” box (in English – “Enable”). A click of the mouse can solve the problem.

It is possible that when the device does not distribute the Internet, the malfunction is related to the radio channel used. Most router models have an automatic configuration feature. If it is missing, you can try installing channel 1 or 6. They are the ones that should be suitable for our country.

It happens that it becomes impossible to connect to a wireless network, because the network displays a message about the incorrect password. It's worth checking the security settings in the web interface. The encryption type set must be AES. The general security standard is WPA2-PSK.

How to solve the problem if there is no access when there is a connection

Quite often it happens that the connection begins to take place, but the process itself takes a long time. The status shows the message “Receiving IP”. After some time the connection is lost.

This means that network clients cannot obtain an address because the DHCP server is disabled. You can check this through the settings in local network. You will need the LAN section, where there should be a checkmark next to the DCHP parameter.

Access problems may arise due to incorrect operation of DNS servers. Incorrect assignment of them for network clients or complete lack of assignment, as well as unstable operation of servers are the three main reasons.

The solution to the elimination problem is as follows. You need to use public DNS. They are provided by Yandex and Google. In the first case, you need to enter 77.88.8.8 in the settings, and for Google this value is 8.8.8.8. The data is entered on the computer in the Internet Protocol properties of any version of TCP/IP.

Conclusion

All of the above are troubles that you can get rid of yourself. In any other situations, it would be better to contact the provider’s technical support or professional technicians.
