Lenovo does not see wifi networks. The computer does not see the required wi-fi point

We have already looked at solutions to many problems that may arise when connecting a laptop to a Wi-Fi network, or during use. But, there is one popular problem that I have not written about yet. This is when the laptop does not see Wi-Fi network. In principle, the problem applies not only to laptops, but also to desktop computer that are connected to Wi-Fi via an adapter (external or internal). The problem when the laptop does not see Wi-Fi can be encountered in Windows XP, Windows 7, Windows 8, and even in Windows 10. If you have Windows 10 installed and the computer does not see your router, then see separate instructions:. Since the solutions there are practically the same, it doesn’t matter what system your laptop is running on. Now we will try to figure out why the laptop does not see wireless networks, on Windows example 7.

Before moving on to any settings, let's try to figure out what problem you specifically have. There are two options:

• When no Wi-Fi network is displayed in the list of networks available for connection. That is, the computer does not find Wi-Fi at all. But, are you sure that there are wireless networks within the radius? Other devices see them.
• And when the laptop does not see only your Wi-Fi network, but others, neighboring networks sees.

I will divide this article into these two parts. You can immediately go to the required section with the solution to your problem.

Another important point. If you have an error on your computer "No available connections" , and a red cross next to the Wi-Fi connection icon, then there is a separate solution to solve this error.

Why doesn't my laptop see wireless networks (not a single one)?

The most popular reasons:

• No in radius available networks (we have already ruled this out)
• The wireless adapter driver is not installed and therefore cannot find wireless networks. Or the driver is installed, but does not work correctly.
• Wi-Fi on the laptop is simply turned off.
• It happens that the Wi-Fi receiver is simply faulty or disabled (for example, while cleaning a laptop from dust).

But, most often, of course, the problem is that the wireless adapter, or in the absence the required driver. This is what we will consider now.

Checking the wireless adapter driver

If you see a connection icon in the form of a computer with a red cross on your notification panel, then the driver is most likely not installed.

To check, we need to go to the device manager. Open menu Start, right click on Computer, and select Control. In the new window, go to the tab device Manager. Open section Network adapters, and see if there is an adapter whose name contains the words “Wi-Fi” or “Wireless”. It looks something like this:

If such an adapter is not there, as a rule, in this case only one adapter (network card) is displayed there, then it needs to be installed. If it is there, then it should be without any icons, like in my screenshot above. If there is an icon near the Wi-Fi adapter, then right-click on it and select Engage. Most likely, you will have to install the necessary driver. We have separate instructions for installation: .

If everything is fine with the driver, then let's Let's check if Wi-Fi is turned on on your computer.

Right-click on the network connection icon, and select Network Control Center and shared access . Then, select Change adapter settings.

After this, the computer should see wireless networks, and you can easily connect to your Wi-Fi network.

You may have wireless networks turned off by a keyboard shortcut on your laptop. You need to check, I wrote about this in more detail in the article:. And if you have a “ten”: .

After these steps, everything should work for you. The main thing is that he appears wifi icon networks with a yellow asterisk, this means that there are networks available for connection.

The laptop does not see my Wi-Fi, but does see others. Solution to the problem.

If above we considered the situation when wireless networks are not displayed on the laptop at all, now we will figure out why the laptop does not see only one Wi-Fi network that we need. And other networks, neighboring ones, are displayed in the list of available ones. This problem appears more often on mobile devices: smartphones and tablets. But computers are no exception.

In this case, the problem must be looked for elsewhere Wi-Fi router. Almost always, the solution is the same: change Wi-Fi channel networks. If the router itself, or you are in manual mode If you set the settings to static channel 13, then the computer most likely will not see the network. Therefore, you need to check and change the channel in the router settings. I wrote in the article how to change the channel on different routers:

For example, change the channel on Tp-Link. You can change it in the settings, on the Wireless tab (Wireless mode). Try to put static channel (just don't put 12 and 13), or set to Auto.

If it doesn’t help, you can still change it Wi-Fi name networks. You can also do this in the settings, on the settings tab wireless network.

Another tip: try moving your laptop closer to the router, or vice versa. Perhaps this is the problem. There are often cases when Wi-Fi catches even close to the router, but on a short distance does not work. This is of course not normal, but somehow specific solution I don't know. Again, you need to try experimenting with channels.

Today's Internet technologies are at a very high level. This is evident in the proliferation of wireless Internet connections from using Wi-Fi. However, there are situations when a device designed to accept such a connection (laptop, tablet, smartphone) does not want to work in normal mode. Lack of access to World Wide Web For modern people- this is worse than the “plague”, the addiction is so strong. What is the cause of the malfunction, and how can it be fixed?

Common Causes of Wireless Network Failure

Actually, to begin the repair, you need to determine the root cause why the laptop does not see wifi.

Here it is worth highlighting the main categories of faults:

• global problems;
• not working router (router);
• malfunction of the wireless network module on the device;
• lack of drivers network card;
• software settings wireless internet in the OS.

Almost all reasons when the wifi network is not visible on a laptop can be eliminated at home. But this must be done with extreme caution so as not to aggravate the problem.

Global Wi-Fi faults

TO common problems applies complete absence Internet on the line due to the provider (for example, preventive shutdown of the Internet everywhere), limited action router, which is why there may be no signal (all transmitting devices have a limited range), as well as an external factor, for example, a power outage at the central control panel of the provider company.

What can be done if there is no wireless Internet due to distance from the router? You can move to a closer room for the signal to appear. The fewer obstacles (walls, rooms, household appliances) will be between the router and the laptop, the stronger and more stable the signal.

Problems with the router

And here this type The problems are already somewhat more serious, although you can fix it yourself. First of all, you need to make sure that the router is working normally. To do this, try connecting another device via Wi-Fi. If a signal is detected, then the problem is solely in the device receiving the signal. If not, then it means there is a problem somewhere in the router itself.

The first step is to try simple measures- just turn off the power from the router, wait 10-20 seconds, and then turn it on again. It happens that the router simply freezes, and rebooting it restores its functionality. If this does not help and the laptop still does not see wifi from the router, you need to move on to the second option.

It is necessary to check whether the incoming network cable. It happens that due to slight deformation or movement, the cable may move away, and as a result the connection will not be established.

Another option for finding out why the laptop does not see wifi is to directly check the incoming connection. To do this, you need to connect the main Internet cable to the device. If access appears, then the problem is somewhere inside the router or its settings.

Important! Sometimes there is interference in Wi-Fi work can be caused by working household appliances, for example, a microwave oven, an oven. But this is rather the exception than the rule.

Laptop problems

Here the range of troubleshooting is very wide, starting from technical reasons and ending software, which can block work on the Internet. As with the router, you can fix almost everything yourself, but you need to know where and what to look for. By the way, if it is not clear what to do if the laptop does not see wifi, then it is better to immediately take the equipment to service center, where specialists will quickly fix the problem.

Technical reasons for the lack of Wi-Fi due to the fault of the laptop

There are several options here. The most common is to disable the button on the laptop keyboard wireless connection. It is located in the area of ​​the F4-F5 keys. Pressing it again turns on Wi-Fi.

Another option is to turn off the toggle switch on the front panel of the device. In a similar way, you need to move the slider to the right position, and the wireless Internet should appear. As you can see, these problems are easily solved in a few seconds. But sometimes the reasons why a laptop does not see wifi are more serious.

For example, failure of the laptop’s network card. No skill or knowledge will help here if this component burns out or does not work for another reason. Only purchasing will help new board, and you will have to be without the Internet for some time.

Software problems with Wi-Fi connection

IN in this case There are a lot of possible faults, but most of them can be eliminated very easily:

1. Conflict with antivirus program installed on a laptop. It is likely that this software simply blocks access to the Network. Therefore, you should temporarily disable it and check access. If you encounter difficulties in how to connect a laptop to wifi with the antivirus turned off, then you need to immediately set up the antivirus or install some other software.
2. Firewall. Standard network windows defender can also add problems, so you need to open its settings and make sure that this channel wireless Internet is not on the list of dangerous connections. If present, then the laptop does not see wifi. You need to completely disable the firewall or remove this channel from its blacklist.
3. The technical error network resources in the operating system. In this case, figuring out what to do if the laptop does not see wifi can be problematic. Sometimes it happens that installing some programs entails changes in network settings. This problem is especially relevant when installing working programs, cryptographers, modules that require working with secure connections, etc. If this fact occurs, then you need to identify the source of the problem and try to restore the system. But more on that later.
4. Installation of third-party software. It is likely that a program is installed for wifi distribution from a laptop. If its settings are incorrect, the device simply turns into a distributing element, and there will be no connection on it itself. But this is a very rare malfunction.
5. But network driver failure is the most common situation among laptop owners. “Crooked” installation, non-original assembly - reasons incorrect operation There can be a lot of network drivers. But the result is sad - the laptop does not see wifi, and even wired connection absent. And there is only one solution - removing old ones and installing official packages, which can be found on the official website of the laptop manufacturer.

Restoring the operating system

This, of course, is the most radical solution, and can entail a variety of consequences. Although usually System Restore simply rolls back Windows to an earlier restore point. If one, of course, was done. When performing this operation WiFi connection will also roll back to the last working state.

By the way, difficulties arising in how to connect a laptop to wifi are also associated with the operating system being clogged with all kinds of garbage and temporary files. As a result, all processes begin to run very slowly, and conflicts arise, including on the network.

As the most difficult option for solving the problem of accessing the Internet via Wi-Fi - complete reinstalling Windows. This is the very last resort, when all means have been tried, but none have brought the desired result.

Additional ways to connect Wi-Fi to a laptop

There are several other ways you can check the functionality of the wireless network on your device.

The same program for distributing wifi from a laptop (to use this method you need a second laptop with this software installed on it) will help determine the source of the problem. If the laptop sees the Wi-Fi being distributed, the reason lies in the router. If not, it’s in the device itself. This is very good way check on which side the disconnect occurred.

Alternatively, you can simply go to the Network and Sharing Center and go to the “Change adapter settings” menu. All installed adapters, including wireless, should appear in the window that appears. It is likely that you just need to turn it on. Or install it.

Afterword

Of course, many of those users who have homes computer equipment, are quite savvy in terms of finding faults and eliminating them. However, Wi-Fi is a special case, as it requires programming skills. Therefore, it is better not to go deeper, but to contact repair specialists.

You can identify the source of the signal interruption, and then repair either the laptop or the router.

Very often, laptop users encounter troubles when turning on or setting up Wi-Fi. The procedure itself seems quite simple, but difficulties and snags often arise due to which the laptop does not connect to wi-fi. What to do if the Internet suddenly stops working? To answer this question, here are recommendations on how to deal with troubles when your laptop does not see WiFi.

For turn on wifi, you need to do two simple steps. And these actions will depend on the manufacturer and model of the laptop. First, we present the inclusion options for the most popular manufacturers.

How to enable WiFi on a laptop

• If laptop ASUS does not connect to wifi, you will have to press the key combination FN + F2.
• Same settings on laptop Packard bell And Acer can be called by the keyboard shortcut FN + F3.
• Laptop HP contains a special button with a symbolic antenna on it. But there are models in which wi-fi can be easily turned on by pressing FN + F12. There are also options for HP laptops that have a regular button with an antenna design.
• Chinese manufacturer Lenovo provided an option where the connection is connected using the FN + F5 key combination. But there may also be models that have a special switch for wireless networks.
• Depending on the model on Samsung laptop You can connect to a wireless network using the FN, F9, or F12 keys.

In order for a laptop to connect to wi-fi, each manufacturer came up with their own original ways. To view this procedure in detail, you should use the user manual included with the laptop. Almost everyone modern laptop equipped with an FN button. It allows you to perform the most different functions to connect the device with other devices. If, for some reason, such a button is missing, then instead there is a switch or another special button. All of them are easily recognized by their characteristic antenna pattern.

Reboot the router

Before you start troubleshooting the problem of lack of Internet. Reboot your router by turning it off and on. In this case, all router settings are saved.

Checking and setting up drivers

When making settings on a laptop, you need to check whether the necessary drivers for this are present and their functionality. The purpose of this check is that the drivers must be present and involved in this moment. To do this, you will have to enter the “Control Panel”, then select “Network and Internet” and here open the “Network and Sharing Center” item, in the left column select “Change adapter settings”

A window will open showing two items, Wi-Fi and Ethernet. In the screenshot below you can see that the laptop is connected to the network via WiFi, but the network cable is not connected.

If in the adapter wifi recording is not displayed, then this is a clear sign of a driver problem. In addition, a yellow icon with exclamation point.

There are times when there is no entry for the adapter at all. This means that the drivers are not installed and the system does not see the adapter. Drivers can be installed from the disk that came with the laptop or found on the manufacturer's website.

If a yellow exclamation mark is displayed, click on it with the mouse and select “Enable” in the window that appears.

Also, the reason that wi-fi stopped working may be the power saving mode, which is involved in given time. To disable it you need:

1. enter the “Control Panel”;
2. find the item “Power supply”;
3. select "High performance";

Having dealt with all these simple manipulations, you can put things in order with the wi-fi drivers.

Turn on the wi-fi adapter

To connect the wi-fi adapter we also perform a number of steps. Open the “Control Panel”, then select “Network and Internet” and here open the “Network and Sharing Center” item, in the left column select “Change adapter settings”. There is a “Wireless Network Connection”, which is a wi-fi adapter. In order to connect to wi-fi, you need to open the dialog box with the right mouse button and here use the “Enable” item.

Connecting to the access point

All that's left to do is connect to the access point. But first of all, you should make sure that it is active. In the right corner at the bottom of the screen you need to find the wi-fi shortcut on the taskbar. If you click on it, a dialog box for managing networks will appear. To connect, you need to select a network and then click “Connect”.

There are times when the system is password protected and asks you to enter it. The system will not be able to connect to the access point until the password is entered. In the presence of open point access, the system connects automatically.

The whole process is considered wifi settings on a laptop.

Once you have carried out all these manipulations, you will not have to do them constantly. But there were cases that for some reason wifi reasons won't want to connect. Often solving connection problems comes down to pressing hotkey and inclusion the desired option. Therefore, if the laptop stops connecting to the Internet, the first thing you need to do is check whether it is turned on.

The laptop uses a lot of energy to maintain an Internet connection. Therefore, it often happens that wi-fi stops working due to the use of economy mode.

External obstacles

It is worth remembering that if the Internet suddenly stops working, the reason may not only be present in the laptop. Wifi depends on external factors, because the radio signal can be weakened by environmental influences. Walls, ceilings, floors, and other obstacles weaken the access point signal and the client device signal. The system always displays the signal level in the form of bars. How stronger signal- the more sticks. The signal at 1-2 short points is quite weak and often because of this it is not possible to use the Internet. It happens that the system does not see the signal at all.

If the laptop does not see WiFi, do not be upset, the problem is often very minor. By following the above recommendations, you can easily learn how to correct errors. And the laptop will always be reliably connected to the Internet.

It would seem that what could be simpler than connecting a router to a computer? It's only a matter of a couple of minutes. But sometimes the result can be completely unexpected, for example, the computer does not see the router, and it is impossible to enter the router settings. What to do in such a situation? For those who want to try to fix the problem themselves, here are some simple tips. But first a few words about possible reasons ah glitch.

Why the computer does not see the router: possible reasons

As for the reasons, there can be quite a lot of them, from the banal incorrect connection to equipment malfunctions, including the router itself and the corresponding ports on the computer ( physical breakdowns or software failures of the device itself will not be considered in detail).

However, the main prerequisites for the fact that the computer does not see the WiFi router, depending on the situation, are the following:

• incorrect connection;
• incorrect access parameters;
• lack of network card drivers;
• inoperability of the Wi-Fi module;
• hidden network.

What to do if the computer does not see the router during a direct connection?

Let's start with a situation where a user tries to connect to a router to perform initial setup via cable directly. It seems that all the cables are connected correctly, but there is still no connection. Well, the router doesn’t see the computer, even if you crack it. What to do?

First of all, if you are absolutely sure that all cables are connected correctly, check whether the address of the router itself is entered correctly in the web browser. In most cases this is 192.168 with the last two digits being 0.1 or 1.1 (other addresses may apply for some non-standard models).

The entry address can be found on a special sign located on back side devices. There is also a login and password that must be entered when entering the settings.

If everything is entered correctly, but the router is not visible, a simple reboot of the router by pressing the On/Off or Power buttons for 10-15 seconds may help. However, it is best to disconnect the router from the power supply completely, maintaining the same interval. If even after this the computer does not see the router, you can try to reset the router settings to factory settings. To do this, there is a small hole in the bottom of the case in which a barely noticeable Reset button is located.

Checking the correct connection

If previous actions did not have any effect, you should check the correctness of the direct connection.

Try plugging the network cable into a different connector on the router or performing similar actions on the computer's network card. If this doesn't work, the cable itself may be damaged. In this case, simply replace it and try to enter the settings again.

Connectivity diagnostics and testing of Ethernet ports

Also, the situation when the computer does not see the Wi-Fi router may be due to a breakdown of the ports themselves. As already mentioned, use a different port or “ring” the one you are connecting to.

However, the reason may also be in the network adapter. In this case, you should make sure that everything for it is installed in the system. necessary drivers(and correctly). If the device is marked in the corresponding manager yellow icon with an exclamation point, the drivers need to be reinstalled. Alternatively, you can also use complete removal device, followed by a system reboot when the driver is installed automatically. In the case of non-standard equipment, it is necessary to use original wheels or indicate location installation file drivers on the hard drive manually.

To get more detailed information it is necessary to diagnose the connection. It is performed from the adapter parameters section, which is located in the menu network connections, located in the standard “Control Panel”. If problems are detected, the system will notify you that they have been resolved.

Checking network attributes

Finally, the reason that the computer does not see the router when using wireless connection, network hiding may be set in the settings.

In this situation, you need to connect to the router directly via cable, enter the settings wireless mode and uncheck the box to enable SSID broadcast (for TP-Link models). In other devices, this may be the item for hiding the network name, setting simply hiding the network (SSID), or something else like that. After this, it is advisable to reboot the device in the manner described above. In addition, it would be nice to restart the main computer system(as they say, you never know).

Conclusion

In most cases, the above methods help correct the connection situation. If none of these solutions helped, in order not to replace the equipment, you will need to reflash the device. Doing this yourself at home is quite problematic, so it is best to contact a service center. If such actions do not give results, you will have to full diagnostics the router is not subject to malfunctions, and if they are identified, replace the device.

But, as practice shows, the most common occurrences are incorrect entry of addresses and parameters when entering settings, breakdowns of cables and ports, and lack of drivers. network cards And wireless modules, and set parameters hiding networks. So at least one of the proposed methods will help.

Problems with the Internet are always unpleasant. They can interfere with work or entertainment, or limit other online experiences. If we are talking about a cable connection, there may not be many possible causes for this problem.

The laptop detects an available Wi-Fi network, but does not connect

One fairly common network problem is when your computer sees a network available to connect to, but for one reason or another is unable to connect to it. This problem may occur for one of the following reasons:

• a problem with the hardware drivers on the laptop - for this reason, the connection may not work or may be interrupted immediately after a successful connection to the network;
• communication interference - Wi-Fi should not be connected too a large number of devices, and you should also make sure that nothing can interfere between your laptop and the router;
• the password for connecting to this network was entered incorrectly - if you entered the security key incorrectly, the connection will not be completed;
• network mismatch - if the connection settings on your computer and the network settings do not match, the connection will not be completed;
• failure of the operating system - in case of some problems with operating system connection will not be made correctly.

Solutions to problems with connecting to a wi-fi network

Let's look at the solution to each of the problems mentioned above one by one, and also study general recommendations for those who encountered this problem in their system.

Error “Windows could not connect to Wi-Fi” and how to solve it

When you try to connect, you may see the message “Windows was unable to connect to the Wi-Fi network.” This error can have several causes. You can determine the source of the problem as follows:

Video: fixing internet connection problems

Security key mismatch when connecting to a Wi-Fi network

The security key is security code for your Wi-Fi network. The user sets it independently so that strangers cannot connect to the network. And if you encounter an error about entering incorrect password, then it was probably entered incorrectly. Do the following to be sure to correct the situation:

You should not tell your security key to strangers - this will lead to additional connections, which in turn will slow down your Internet speed.

Inconsistency between saved network parameters

After creating a new connection, you may often see an error with the text “The network settings saved on this computer do not meet the requirements of this network.” This problem often occurs after self-configuration router. To fix this situation, all you have to do is delete the connection and then create it again. This will update all settings and establish a connection again. This is done as follows:

In Windows 10, this problem is solved a little differently:

The problem may arise, for example, due to a careless change in the data in the connection settings.

Other ways that can help you connect

And now let's look at a few general solutions, which can help you with various connection problems. In our case, when it is impossible to connect via Wi-Fi, these methods will also help.

Reboot the router

The simplest method, which is recommended by all providers first of all. Of course, this will not help with serious problems, but it can eliminate one-time connection problems. The best way to reboot is as follows:

Checking and installing network drivers

Update network drivers no more complicated than drivers for any other equipment. Do it with automatic system You can download drivers as follows:

1. Press the Win+X key combination to open the menu quick access and select the “Device Manager” section there. Another way to get to this menu is to right-click on the Start icon.

   

   Select the "Device Manager" section from the quick access menu

2. In Device Manager, find the Network Adapters section. Expand this tab and you will see your network devices. And then click on right button mice on available hardware. After it opens context menu, select the “Update drivers...” action. In order to determine whether a device needs to update its drivers, pay attention to its name and the presence or absence of an icon indicating the need to update drivers.

   

   Open the "Network adapters" section and click "Update drivers" on the desired device

3. You will be asked for an update method. If you have an Internet connection (for example, using a cable, since a Wi-Fi connection is not available), then just click on the “ Automatic search updated drivers."

   

   Select "Automatically search for updated drivers" if you have a network connection

4. Wait until the search, download and installation of drivers is completed.

   

   Wait for the drivers to be searched on the network and installed.

5. If there is no network access, you must download the driver for your network adapter from another device and select “Browse for driver software on this computer.”

   

   For independent search drivers, select “Browse for driver software on this computer”

6. Specify the location of the folder with drivers for further installation.

   

   Specify the location of the drivers on your computer and click on the “Next” button

7. After the installation is completed in one way or another, restart your computer.
8. Try connecting to the Wi-Fi network again to see if your problem is resolved.

If a simple update does not help, try completely uninstalling the driver and installing it again using the same method.

Resetting the router

If problems with the Internet do not go away and you still cannot connect to Wi-Fi, you should resort to a more radical way to fix this problem. Namely, reset the router settings and configure it from scratch. You should not do this if you are unsure own knowledge and attentiveness - you risk being left without Internet access. You can reset the router in the following way:

After performing the reset, the device will return to factory settings. Most likely, you will not have to configure anything manually after this and your Internet problems will already be resolved. But in case you still have to make the settings yourself, this is done as follows:

This will complete the setup of your router. Depending on the equipment model, some items may be named slightly differently, but the setup will occur in the same way.

Video: how to configure a router

If your laptop finds a Wi-Fi network available for connection, then the problem is not so bad. And after studying this article, you will surely be able to install stable connection. Use the Internet for work and entertainment, and most importantly, do not panic in case of problems. Because now you know how to fix them at any time.
