Common problems with Rostelecom routers. Wi-Fi without Internet access: the yellow exclamation mark in the tray is lit. Recommendations for solving the error

WiFi is a unique technology wireless communication, which is incredibly popular all over the world. Nowadays there are very few people who prefer regular wired Internet. Connecting and setting up Wi-Fi is not difficult. But even in such a perfect system, sometimes errors occur due to which Wi-Fi stops working. The most common is a problem with connecting to the Wi-Fi router.

Some people are faced with a situation where the router is connected to the network and works, but does not distribute data: the computer cannot “see” the available network. Why does this happen? There may be several reasons for this:

lack of installed network drivers;

hardware type errors;

random shutdown of the connection to the computer - it is obvious why in this case the device does not work as it should;

Wi-Fi module malfunction;

Wi-Fi router malfunction.

There are other problems, but the ones listed above are the most common reasons, for which the device does not work. Therefore, we will focus on them.

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 right-clicking.

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. Testing is carried out differently on different operating systems. But it all comes down to one thing: you need to get into the “Network Control Center”.

Exists 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 to not 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 of the situation is to contact a 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 to network clients or complete absence destinations, as well as unstable operation of servers - these 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.

Not working wi-fi - this phenomenon is quite common, and most often occurs if any changes are made: after reinstalling the OS, updating firmware, replacing the router, and others. Sometimes finding the cause of Internet problems is difficult even for experienced professionals.

Wi-Fi does not work on a laptop, what is the reason?

The reasons for the inability to connect to Wi-Fi can be very different; they can be divided into simple and complex. And in this article we will try to consider the main ones.

Banal (simple) reasons for Wi-Fi not working

You haven't paid for the Internet - pay for it.
The router is not turned on - turn it on.
No Wi-Fi coverage - move closer to the router.
Your router is buggy - reboot it.

Serious reasons for Wi-Fi not working

If you have a problem connecting to Wi-Fi, then first you need to determine what the reason is: in the router or in the laptop.

The easiest way to find out what the problem is is to connect another device to your router or connect your laptop to a different Wi-Fi network.

Wi-Fi router/router is not configured

Before connecting to a wireless network, you need to configure your router. If you have not done this, then you should find instructions on the Internet for the router of your model and for your specific provider.

To find out if the connection from the provider is working, you need to check the WAN tab in the admin panel or the indicator on the router. If the connection from the provider does not work, then the problem may be as follows:

The admin panel contains incorrect settings for connecting to the provider.
The router is faulty.
Problems on the part of the provider. To exclude or confirm this option, you can contact your provider.

Wi-Fi does not work on a laptop - the receiver is faulty (burned out)

Sometimes Wi-fi laptop it just stops working. The network connection is either missing or unstable. The reason may be a breakdown of the Wi-fi module in the laptop. Then it may need to be replaced or repaired.

Most probable cause The fact that the laptop does not connect to the Internet after reinstalling the operating system is the inability of your new operating system to find and install a driver suitable for your network card.

As a rule, to install a driver on a network adapter, you need to use the driver disk that comes with your laptop, or you can download the required driver from the manufacturer’s website for the specific model of your device.

You can check whether a driver is installed on the network adapter in Device Manager.

Wi-Fi module is not enabled on your laptop

There are 2 ways to enable the Wi-Fi adapter programmatically if it was previously disabled in the OS settings:

1. Through the Network and Sharing Center. You need to enter the ncpa.cpl command in the input window after pressing the Win+R combination. This command will open “Change adapter settings”, from there you need to go to “Wireless network connection”. If the network adapter icon gray, then you need to turn it on.
2. Through the device manager. If the adapter is disabled in Device Manager, the “Wireless Network Connection” icon will not appear in Network Connections. Then, as in point 1, you need to press Win + R. Then you need to enter the command devmgmt.msc, it will open the device manager. Next, we find a device that contains Wi-Fi or Wireless in its name, and after right-clicking, you need to click “Engage”. If the adapter does not turn on, then you need to check if there are suitable drivers.

Firewall or antivirus is blocking internet access

Sometimes your OS's security features, such as antivirus or firewall, can prevent your laptop from connecting to Wi-Fi.

If the problem is the firewall, then solving the problem is not difficult: you just need to disable it in the system settings.
If the antivirus causes obstacles, then you must either end the necessary processes through the task manager, or you can disable the antivirus itself.

Viruses and Malware block Wi-Fi

If you do not have an antivirus installed or it is outdated, then there is a high probability that you will encounter a blocker virus. Such viruses block your access to the Internet, allegedly due to a violation of the law. This virus works very simply: it sets its DNS servers in the network settings, and your browser finds only the fraudulent site. To solve the problem, you just need to change the DNS servers to those that suit you.

There may be too many devices connected to your Wi-Fi. Look and turn off the most active ones who are clogging up the Internet channel.

Many factors affect Wi-Fi speed. These include both external problems and the problem may be in the device.

The most common reasons:

A laptop network adapter and a Wi-Fi router have different capabilities.
An unauthorized connection has occurred to your router.
The influence of electrical appliances.
Incorrect router location.
The wireless channel is being affected by another router.
The equipment is outdated.

Advice: To make your Wi-Fi work faster, try rebooting the router, moving it to another location, or updating its firmware.

If Wi-Fi on the laptop worked properly before reinstalling Windows, then the reason could only be in the drivers. Right-click on the “My Computer” icon, go to the “Hardware” tab, then click on the “Device Manager” button. In the list that appears, icons with an exclamation mark indicate those devices for which the driver is not installed.

Find out your model motherboard(if you have a desktop computer) or the model of your laptop (you can look under the battery). Then go to the manufacturer's website and download drivers for your network card. After installing them, Wi-Fi will appear on your computer again.

The wifi button does not work on a lenovo/HP/asus/acer laptop - how to fix it?

You can fix a non-working button only by replacing the entire laptop keyboard; order a keyboard from your laptop and replace the old one with a new one yourself or take your laptop to a service center.

Important! While the button does not work, you can turn on Wi-Fi on your laptop without a button, using OS Windows. To do this, click: “Start” - “Control Panel” - “Network and Internet” - “Network and Sharing Center”. On the left, click on the item: “Change adapter settings.” Next, look for a wireless network, right-click on it and select ENABLE.

What to do if the wifi driver on the laptop does not work?

In this state of affairs, we have no options; we need to either update the old driver or remove the existing driver and install a new one.

To remove the current driver from your Wi-Fi, right-click on the “My Computer” icon, go to the “Hardware” tab, then click on the “Device Manager” button. Next in the list, look for your network card and remove all network equipment, then restart the computer and install a new driver for Wi-Fi.

It is also possible that your Wi-Fi adapter (network card) does not have new drivers for modern operating systems, in which case you need to return the previous operating system.

Wi-Fi technology is very widely used in life modern man, because it allows you to easily and quickly solve problems with connecting to the Internet without using conventional wires. This is especially true when using laptops, which can be used to access the Internet in any convenient place thanks to the presence of a built-in Wi-Fi adapter.

That is why the situation when Wi-Fi does not work on a laptop leads to significant inconvenience and even some problems. There are many reasons why Wi-Fi may not work on a laptop computer. It is simply unrealistic to solve the most serious of them on your own without the help of specialists, but there are quite a lot of them that can be eliminated on your own. Let's look at them.

Is the problem with your laptop or router?

A fairly common problem that a laptop has stopped connecting to the WiFi network is not a problem with the laptop itself, but with the settings of the router that distributes the network. Thus, the laptop can be configured correctly, but Wi-Fi still does not turn on precisely because it has nothing to connect to.

To rule out the possibility that the problem is related to this, you should try to connect to the network from any other device that is equipped with a Wi-Fi adapter - from another laptop, smartphone, tablet, etc.

If Wi-Fi does not work from another gadget, then the problem lies in the Wi-Fi router distributing the Internet. If the connection is successful, the problem is in the laptop and before solving it, you first need to determine why Wi-Fi stopped working.

Hardware enable adapter

Based on such diagnostics, it is possible to accurately determine that this problem arose precisely because of the laptop. When Wi-Fi does not work on it, you can try using several methods.

The first one is to check if the wireless adapter on your laptop is enabled. Almost all modern models have light indicators for the operation of the WiFi module and there are special key combinations to enable it in hardware.

Typically, a lit indicator indicates that the module is turned on. If the indicator does not light up at all or lights up in red, then Wi-Fi is not working precisely because of the wireless network adapter. It must be turned on.

Most often, such indicators are located directly on the keyboard, side or front panel of the device case. Sometimes they are located on the monitor body or near the touchpad.

To enable the module of such a network, press the key combination Fn and one of the system keys F1-F12. The specific combination depends on the laptop manufacturer. Usually, the corresponding antenna icon is located on the desired key. If it is not there, then to turn on Wi-Fi you should try pressing the standard combination for a particular model:
Fn+F3 for Acer;
Fn+F2 for Asus, Dell or Gigabyte;
Fn+F5 on Fujitsu devices;
Fn+F12 on HP laptops.

After pressing the corresponding keys, we check whether the wireless connection module operation indicator lights up or whether it stops glowing red. After this, you should try to connect to the network again. If this does not help, move on to the next step.

Software enablement

When Wi-Fi stops working and turning it on in hardware doesn’t work positive results, you also need to enable it programmatically, which is done directly from the operating system under which the laptop runs.

To programmatically enable WiFi that has stopped working on Windows 7, 8 or 10, you need to perform the following sequence of actions:

1. On the notification panel, which is located near the clock, select the network connection status icon;

2. From the list that opens, select “Network and Sharing Center” or “Network Settings” depending on the version of the operating system;

3. The next step is “Changing adapter parameters.”

Among the list of all existing connections You need to pay attention to the color of the “Wireless Network Connection” icon. If your WiFi does not work and the wireless adapter is disabled, the connection icon will not be highlighted. In this case, right-click on its icon and select “Enable” from the context menu that opens. The color of the connection icon should change.

The wireless network adapter turns on; all you have to do is find it in the list of available ones. wireless networks the one you need and connect to it.

If, after such actions, Wi-Fi, which has stopped working, continues to be inactive, you need to proceed to to the next method solving the problem.

Driver installation and update

Quite often, the wireless Wi-Fi connection does not turn on due to the lack of a driver or when it is very outdated. To determine whether the driver is installed, you need to select “Properties” from the context menu of the “My Computer” icon, which is located on the desktop or in the “Start” menu. Next, in the window that opens, select the “Device Manager” command from the menu on the left.

In the new window that opens with a list of connected devices, you need to find the name of the laptop’s wireless network adapter. Usually its name is “Wireless Network Adapter” or “Wireless Network Adapter”, along with which the device manufacturer should be indicated: Realtek, Atheros, Qualcomm or something else.

Having found the desired item and right-clicking on it, select “Properties” from the context menu. In the window that opens, there should be an item “Device is working normally.” But even if there is a mark about normal operation device, this is far from a guarantee that the correct driver version is installed and Wi-Fi is turned on correctly. To check it, in the window with the properties of the wireless device, go to the “Driver” tab and pay attention to the items “Date of development” and “Vendor”.

In the event that the supplier is Microsoft or the date of development of the program is several years behind the current one, go to the official website of the laptop manufacturer and download the latest official version drivers.

The same should be done if there is no wireless adapter among the list of installed devices.

If the wireless communication module is present in the list of devices, but is marked with a yellow exclamation mark, this means that the device is disabled, as a result of which the network has stopped working. In this case, opening the device properties window, you need to click the “Engage” button.

Another reason why Wi-Fi stopped working on a laptop may be that the energy-saving mode is enabled, which prevents the wireless connection from working. To disable it, you need to do the following:
1. Open Control Panel;
2. Select the “Power Options” icon;

3. In the window that opens, select the “High Performance” or “Balanced” mode.

External obstacles to the signal

It's also worth noting that a broken wireless network can also be the result of more than just laptop problems. The wireless signal depends on some external factors which may weaken it. Ceilings, walls, floors and similar obstacles significantly degrade the signal quality of the access point and laptop.

As you know, the signal quality on a personal computer is displayed in the form of several marks - the more of them, the higher the quality of the signal. If the wireless connection level is displayed as 1 or 2 marks, then you don’t have to try to use WiFi - in this case it will not work normally.

In this case, you need to move the router closer to your workplace, move workplace closer to the Wi-Fi router or buy a new, more powerful router.

If all else fails

If none of the tips above helped, you can use a simple, but often effective solution: restart both your computer and your wireless router. Please note that after a reboot, the router turns on for up to 5-10 minutes before it starts distributing the network. Be patient. Also, despite the opinion of many skeptics, sometimes the troubleshooting function that is included in the wireless network helps to solve problems with the wireless network. operating system Windows.

Thus, most of the existing solutions to problems related to the fact that Wi-Fi has stopped working on a laptop have been listed above. Almost all such methods and recommendations can be used by anyone who is faced with a similar problem, since this does not require any special skills.
If nothing helps, and the wireless network does not start working, there is only one option left - go for help to a quality service center, where they can solve any problems with the laptop.

If the article did not help solve your problem and Wi-Fi still does not work, write in the comments, I will try to help.

Today I decided to write an article on a very popular problem when the WLAN light on the router does not light up and there is no Wi-Fi network. That is, when the router stopped broadcasting Wi-Fi network. Owners of routers from different manufacturers face this problem: TP-Link, ASUS, D-Link, ZyXel, Tenda, Netis, etc. It doesn’t matter what router you have. If the Wi-Fi (WLAN) indicator on it has stopped lighting and the Wi-Fi network has disappeared, then now we will try to figure out this problem.

On different routers (different manufacturers and models) The WLAN indicator looks different. But it is on almost every router. Typically, it blinks when data is being transmitted over the wireless network. The light bulb itself can be labeled "Wi-Fi", "2.4GHz", or "5GHz". Or maybe just an icon

In any case, when the WLAN indicator on the router is not lit or blinking, this is no longer normal. As you already understood, WLAN is Wi-Fi. Wireless network.

Most often, the problem is the following:

Accidentally pressed the button to turn off Wi-Fi, which is found on many routers. After pressing it, the router stops distributing the Wi-Fi network, and the WLAN light, of course, does not light up. At the same time, the router continues to work and distributes the Internet via cable. But the devices no longer see the Wi-Fi network, since it doesn’t exist.
Some kind of glitch in software. In this case, rebooting, resetting settings, or updating the router firmware helps. You also need to check the Wi-Fi settings in the router control panel.
Router failure. I have seen cases more than once when a router stopped distributing a Wi-Fi network due to a technical breakdown. If all else fails, the Wi-Fi indicator still doesn’t light up, then you need to take the router in for repair. (possibly under warranty), or buy a new one. If this is your case, then take a look.

Let's check this very button that turns off Wi-Fi on the router. Let's also check what's in the control panel. Because this is most often the problem.

The WLAN light does not light up, the router does not distribute Wi-Fi. What to do?

First of all, we take our router in our hands and look for a button on it that is responsible for turning it on/off wireless wifi networks. Typically, this button is labeled "Wi-Fi", "Wireless On/Off", or simply with a wireless network icon

Some routers do not have such a button.

If you find this button, just click on it once. Wait a little and look at the WLAN indicator, it should light up. If this does not happen, then reboot the router (turn off the power for a couple of minutes), and try pressing the button again. You can press and hold for three seconds. It all depends on the router and settings. In any case, this should help, and the router should distribute Wi-Fi.

Checking the status of the Wi-Fi network in the settings

If you don’t find the button, or if the WLAN network does not appear after clicking on it, you can also check the status of the wireless network in the router’s control panel.

We connect to our router via cable, there are no options here, and go to the settings. If you don’t know how to do this, then look. It may happen that you will not be able to access the control panel, in this case, see the article. If you can’t log in and the recommendations don’t help, then most likely the router is simply broken.

If you are lucky and the control panel opens, then look for the “Wireless Network”, “Wi-Fi”, “Wireless” tab and open it. It all depends on the model of your router. Let's look at the most popular ones.

This is what Wi-Fi settings look like on routers TP-Link :

Please note that the checkbox next to "Enable Wireless Router Radio" must be checked. (Enable wireless broadcasting).

On routers ASUS Open the "Wireless Network" section, "Professional" tab. Opposite the “Enable radio module” item, the switch should be next to “Yes”.

On ZyXEL Keenetic, in the “Wi-Fi network” section there should be a checkmark next to the “Enable access point” item.

If you have some other router, then the page with the wireless network settings will not be difficult to find. If it doesn’t work out, write the model in the comments, I’ll tell you.

Nothing helps, the router does not broadcast the Wi-Fi network, the indicator does not light up

If you have already tried everything possible, but the router still does not start distributing Wi-Fi, and the WLAN light still does not light up, then most likely the router is broken. That is, the problem is not in the settings or software, but in the hardware.

What else can be done?

Reset your router to factory settings. Find the “Reset” button on the router, press and hold it for 10 seconds. As a rule, the button is recessed into the case, so you need to press it with something sharp. If that doesn’t work, type a query in the search on our website (at the very top), for example, “reset settings on TP-Link.” We have instructions for all popular manufacturers. Or write in the comments, I’ll tell you.
If you were able to access the router settings, then update the firmware. We also have many instructions for different routers on our website. Look for instructions for your model through the site search.

To be honest, these tips are unlikely to help. But, before you take the router for repairs, or go to the store for a new one, you need to try resetting the settings and updating the firmware. Well, also press the "Wi-Fi" button (if you have it), maybe there is still a problem there, and the WLAN indicator will start to light up, and the router will distribute the wireless network.
