The computer sees Wi-Fi but does not connect. Solving WiFi problems

This question applies not only to laptops, it is quite suitable for a regular personal computer. So keep this in mind.

So why won't my laptop connect to Wi-Fi? What could the user do wrong when working with the network, did he install the drivers for the router correctly, and did he turn it on at all? There can be many reasons why the network is not visible to the computer, so I will try to talk about the most popular ones.

Connecting to a wireless network step by step

So, let's look at what the user might have missed when connecting to the network. To do this, we'll look step by step at what you need to do to connect to Wi-Fi.

1. Press the button on the laptop that turns on the Wi-Fi adapter. It usually either says wi-fi or has an antenna icon.
2. It is possible that the adapter is disabled through Network Sharing Center or in Device Manager, enable it there.
3. Connect to an available network.

If we talk about the first option, then, as you understand, everything is easy here, you just need to press a special button to turning on wi-fi. This is usually done with a keyboard shortcut Fn+network button.

The second option could be this. Some laptops have special button, which also includes wi-fi, if you find one, use it. Well, go to the Network Sharing Center and Task Manager, make sure that everything is turned on there too.

What to do if the laptop does not want to see the network?

If you tried to turn on wi-fi, but it didn't work positive result and the network is still not found, then most likely you should check the router itself.

After all, it is he who is the access point and the cause of all problems may be precisely in him. The simplest thing to do is restart it, this usually helps, also restart the computer. Check the wires to see if everything is connected and is not coming loose anywhere.

If the above method did not help, then the reasons may be a little more serious.

• The computer has crashed or is damaged;
• Connection errors;
• The router has a malfunction or is completely broken;
• The network is not turned on.

The first option is to check the drivers

A driver is a set of programs that controls our equipment; if something is “broken” in this complex, then in our case, it is unlikely to connect to the network, therefore, we need to check the status of the drivers.

We can view the drivers in our favorite device manager. In Window 7 and 8, you can access it through the Control Panel; in Windows 10, right-click on the Start menu and select "Device Manager".

In the device manager window that opens we find the tab "Network adapters", open it. If there is no such tab, then the problem is still in the drivers. Also, if network hardware indicated there by a yellow exclamation mark, then there are no drivers.

In this case, you can download drivers on the Internet from the manufacturer’s website, for example, or.

If you have a disk with drivers, this greatly simplifies the task; you don’t have to look for anything.

The second option is to check the connection status

If you have figured out the drivers or are sure that they have nothing to do with it, then let’s try to check the status of the network itself, for this we will go to the network control center. In Windows 7 you can access it through the Control Panel, and in Windows 10 you can right-click on the wi-fi network, which is located on the taskbar, where you can select the time "Network Control Center and shared access» .

As soon as you go there, look for the button on the left "Change adapter settings", click on it.

In the next window you will see all the networks you have. We are interested in "Wireless network". You can try turning it off and then turning it on.

In our case, it is clear that the network is working, if there was a red cross there, then the network would not exist; if the icon was gray, it means that it is disabled.

The third option is network diagnostics

This option does not always help, I don’t even know why this network diagnostic is needed, but it can show what the problem is. To check the network, we also go to the control center, adapter settings, right-click on our network and select "Diagnostics". The same can be done if you click on Wi-Fi network on the taskbar near the clock.

If the check shows that something is wrong, then try following the instructions, for example, connecting the adapter, restarting, and much more. Usually diagnostics tries to solve the problem on its own.

Option four – faulty router or network card

This is the saddest option if the router breaks down or burns out LAN card, then the router will have to either be changed or sent for repair, the same with the network adapter.

Only you know why the network card burned out or the router broke down. This may be due to electricity or careless handling of equipment. We'll have to repair it and pay back the money.

I think the most common mistake could be that the user is too far from the access point, due to very weak signal the network will not work, but this option, although it looks childish, also has a place to be.

I painted possible problems with the network and a little about how to solve them, I think that you can install the drivers yourself and turn on the “Wi-Fi” button, so I didn’t go into all this detail. If you have any idea why your computer won't connect to Wi-Fi networks, then be sure to write about it in the comments, everyone will be very interested to know about it. And don't forget to ask questions.

Laptops have an advantage over personal computers represented by a built-in Wi-Fi adapter, with which users can connect to wireless Wi-Fi networks. However, PC owners can easily purchase an external Wi-Fi adapter and also enjoy the benefits of wireless technology.

However, some PC users report that sometimes their external Wi-Fi adapters, for some reason, cannot connect to the network provided by their router. The root of the problem can be many things: a faulty driver, problems with the router, operating system settings, etc.

In this article we will tell you what can be done if your Wi-Fi adapter cannot connect to the distributed network.

Checking the distributed Wi-Fi network

Let's first think about this: have you thought that perhaps the problem with connecting to the network is not in the Wi-Fi adapter, but in the router, which simply does not distribute the wireless network? Checking this is quite simple: take another device that is capable of connecting to a Wi-Fi network and try connecting to your router using it.

If there are no other devices, you need to go to the settings of your router and make sure that it is activated for distribution wireless network. There are times when the settings in such devices, for some reason, go wrong on their own. All you need to do is log into the interface and activate the Wi-Fi sharing option.

Turn off Airplane mode

As we all know, Windows 10 has a rather convenient Airplane mode, with which you can turn off everything wireless modules located on your system. Of course, after activation this mode Your external Wi-Fi adapter is also deactivated.

Airplane mode is extremely useful for mobile devices and laptops, but on desktop computers it is absolutely unnecessary. However, you could accidentally turn it on, for example, by digging through the settings or using a special combination. There are also opinions that the “Airplane” mode can be enabled by third-party software.

Deactivating Airplane mode is incredibly simple: click on the Notification Center icon and click on the button for the mode of the same name. That's all that is required of you. If you don’t find this option in the Notification Center, you can go to System Settings and disable it there.

Restarting the Wi-Fi router

Having realized that the wireless network distribution is activated and your Wi-Fi adapter is not blocked system settings computer - try restarting your router. There is a possibility that it has started to malfunction, as a result of which you cannot connect to the network using third party devices with Wi-Fi adapter. Restarting is extremely simple: unplug the router from the power supply for about ten to fifteen seconds, and then plug it back into the network. It is worth saying that routers can often fail, which leads to a number of unpleasant problems: reduced speed network connection, blocking certain connections or all access to the Internet.

Using the troubleshooter

Enough in a simple way The solution to network connection problems is to use the network troubleshooter. You don't have to go anywhere to get it, download it or search online, because this remedy represents system utility, which is incredibly easy to access. To do this you will need to do the following:

• go to Settings;
• go to the “Update and Security” section;
• go to the “Troubleshooting” tab;
• click on “Internet Connections”;
• click on the “Run the troubleshooter” button;
• follow the instructions on the screen.

It is worth saying that this systemic remedy, unfortunately, almost never solves any problems that have arisen in any element of the system. However, sometimes the stars do align in the sky - and a miracle happens. Try this troubleshooter and then check if you can connect your Wi-Fi adapter to your wireless network.

Updating Wi-Fi adapter drivers

You may not be able to use your Wi-Fi adapter normally simply because its drivers are outdated. By updating the drivers, you can get rid of any problems with your device. You can run the drivers through Device Manager:

• press Windows+X;
• select "Device Manager";
• find and open the “Network adapters” section;
• right-click on the Wi-Fi adapter and select “Update driver...”;
• select to automatically search for a driver on the Internet;

After updating the drivers for the Wi-Fi adapter, try connecting to your router’s wireless network again. In most cases, users who experience similar problem, they resolve it by updating the driver for the device.

Roll back to a previous driver version

However, even a new version drivers may cause problems when using Wi-Fi adapter, however, it all depends on the device manufacturer. Maybe, latest version The Wi-Fi adapter driver is extremely unstable or it is incompatible with your computer. In this case, you can try to rollback installed driver before previous version.

You can do this in the same way using Device Manager:

• get to your Wi-Fi adapter in the list of network devices;
• Double-click the left mouse button on the Wi-Fi adapter;
• go to the “Driver” tab;
• click on the “Roll Back” button;

Having rolled back to the previous version of the driver for the Wi-Fi adapter, try using it and connecting to the router’s Wi-Fi network. If the problem really was the driver, then you will immediately understand it.

Temporarily disable the firewall

If none of the above helps you resolve the problem, then your wireless network may be interfering with your Windows Firewall, which, for some reason, blocks the network connection. One way or another, you can check this simply: you just need to temporarily disable the system’s firewall.

You can do this as follows:

• press Windows+S;
• enter and select the request “Windows Defender Security Center”;
• go to the “Firewall and Network Security” tab;
• deactivate the firewall for the domain network, frequent network and public network;

Try using a Wi-Fi adapter and connect to the wireless network provided by your router. We hope that everything finally worked out for you, and that your adapter is still working properly.

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 could not connect to the Wi-Fi network.” This error can have several causes. You can determine the source of the problem as follows:

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 complete.

   

   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 again wi-fi networks to make sure 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.

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.

If Android does not connect to WiFi, then most often the user sees the “Obtaining an IP address” message or the “Authentication Error” notification. Another common connection error is that Android writes “Saved, WPA/WPA2 protection,” but does not connect to the Internet.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Possible causes of failure

If Android cannot connect to Wi-Fi - for example, instead of an active Wi-Fi icon, you see gray button and icon Exclamation point- then the reason for this could be:

1. Wrong from Wi-Fi.
2. Setting an unsupported security type or standard wireless communication in the router settings.
3. Problems with Android firmware.

The first step is to understand which device is having problems. If only your phone does not connect to the point, then the reason should be sought in its settings and firmware. If no device finds the wireless network, then you should check the router settings.

"Obtaining an IP Address" message

If, when you try to connect, a message with the text “ ” appears, but the connection is not established, then the reason for this may be that the DHCP server is disabled in the router settings or problems in Android work. A simple reboot of the router can help.

If the DHCP server fails, restarting the device will fix it. When saving an error:

1. Open your router settings.
2. Make sure the DHCP server is enabled.

Increase

Depending on the router model, the procedure for enabling/disabling DHCP may vary, so you will need to look for instructions for your device.

Authentication Error

If connection authentication fails, the problem is most likely due to incorrect input. Wi-Fi password. To resolve the error:

1. Forget it wireless point on your phone/tablet.
2. Reboot your router.

Increase

1. Change your password using only letters and numbers.
2. Make sure that WPA2-PSK is selected for network authentication.

Increase

If your phone does not support the WPA2-PSK standard, then select another mode - WPA, WPA2. It is clear that in the subway or mall you can't do it, so all you have to do is accept it. But at home or in a hotel, you can access the router and check the wireless network settings.

Saved, WPAWPA2 protection

If the connection is made without a password, then there cannot be an authentication error. However, there is another situation - the network is saved, but . Usually rebooting the router helps, but sometimes you have to go into the settings quite deeply.

Increase

Also, look at the number of devices allowed. If it is “0”, then there are no restrictions.
