How to fix WiFi problems in Windows 11 and its most common failures

At present it is really strange to have a computer that does not connect to the internet to be able to work on the network, and sometimes whether it is a desktop or laptop computer we do it through WiFi. It is known by all that the most recommendable is to make this connection through the cable, but sometimes due to the location of the router or simply the fact of having to be on the move, the wireless connection is used.

But just like with other features, WiFi can fail on more than one occasion and make it impossible to connect to the internet without a connection. This is one of the most common problems when we talk about a computer that owns Windows 11. In this article we analyze the most frequent errors and how to solve it.

Check if the fault is in the router itself

One of the most common problems in relation to the Internet connection is in the router itself. That is why the first thing to do is connect to a network of a different frequency. You have to know that many routers have two different network bands: 2.4 GHz and 5 GHz, and this is how it will appear in the list of networks. To do this, you will have to switch between them to check if you can have an internet connection or not. This is mainly because the 5 GHz network is recommended for when we are close to the routerbut if the computer is far away it is better to opt for the 2.4 GHz one even if it is more saturated.

Obviously another of the classics within the revision of the router is the fact of restarting it to be able to create a new connection with the internet service provider. To do it correctly, the following steps must be followed:

1. Disconnect the power cord from the router.
2. Wait 30 seconds minimum.
3. Reconnect the router to the power source.
4. Please wait a few minutes until all the LED lights turn on and the connection with the devices is made again.

At this time, you will be able to try to connect to the internet again with your computer. If it still doesn’t work, it’s important Check if the connection can be made with the rest of the devices in the home, such as the mobile. If so, then the fault will be in the computer hardware or in the software itself with Windows 11.

Detect where the problem is

With Windows there are ways to know where the problem of the internet connection may be. Specifically through the command prompt you can perform a ping test that will allow us to know if the computer gets a response from the router and this may indicate that the problem is with the provider itself. To do this, the following steps must be followed:

1. Open the Start menu.
2. In the search engine type “command prompt” and run it as administrator.
3. Type ipconfig and write down the IP address that appears next to Default Gateway. Normally it will be 192.168.1.1.
4. Again in the CMD type ping and press Enter. The command example would be ping 192.168.1.1
5. If you get a response with the phrase “Response from 192.168.1.1: bytes=32 time=5ms TTL=64″ it can be said that the problem is with your system provider. But if you do not get any response, you will have to take different steps to solve it.

Run network commands to reset the network

In computing we always say that the most logical step to solve any problem is to restart the system. And precisely the same can be done with the network connection to the be able to reset all its parameters by renewing the IP address and clearing and resetting the cache of the DNS client resolver. Personally, this is one of the steps that has always worked for me when I have had problems in Windows 11.

In order to carry it out, they will have to enter different commands in CMD and then check if the internet connection has been restored. The steps to follow will be the following:

1. Open the Start menu.
2. In the search engine type “command prompt” and run it as administrator.
3. In the window that opens, type the following commands in the order marked:

• netsh winsock reset and press Enter.
• netsh int ip reset and press Enter.
• ipconfig /release y press Enter.
• ipconfig /renew and press Enter.
• ipconfig /flushdns and press Enter.

Uninstall adapter driver and reboot

In the event that these steps did not work correctly, it is important to uninstall the network adapter driver. This is responsible for offering the precise instructions to be able to correctly receive the Internet connection by the router. But sometimes it may end up failing and the smart thing to do is to uninstall it and force Windows to reinstall it. It is important to previously locate the driver on the internet with another computer and have a backup copy on a flash drive. This is because if the failing PC is offline, you won’t be able to reinstall it.

In order to carry out this process, you will have to follow the following steps:

1. Open the Start menu.
2. Writes device administrator and select Device administrator in the listing.
3. In the list look for network adapters and find your adapter.
4. Right-click on it and click Uninstall device.
5. Reboot the PC.

When the device starts up, and if all goes well, this driver will need to be reinstalled and the internet connection will be restored. But if you haven’t installed it, it’s important rescue the backup that has been made previously.

The bug may be in the latest Windows 11 update

It is a fact that sometimes the updates that come from Microsoft sometimes give more bugs than solutions. You can know if this is responsible if the failure has been filed right after performing a Windows 11 upgrade. In this way, you should choose to temporarily uninstall the latest update that has been installed through Windows Update. The steps to follow are those:

1. Tap Start.
2. Scroll down to Settings.
3. On the side, click on Windows Update.
4. Click on Update history.
5. Select in Uninstall updates.
6. Select the latest installed update and tap on uninstall.

Check for driver updates

In the event that uninstalling the latest Windows 11 update has reestablished the internet connection, you will have to search for updates to the driver itself. This is something that is done by following these steps:

1. Open the Start menu.
2. Writes device administrator and select Device administrator in the listing.
3. In the list look for network adapters and find your adapter.
4. Right-click and click Update driver > Search for updated driver software automatically.
5. If the update is found and installed, restart your PC.

If no type of new driver is found, it is important to also visit the manufacturer’s website and track down the version numbers they have released and check them with the ones you have installed on your computer.

reset network

The last step to take into account is the restoration of the network, which is a radical decision when remove any network adapters that have installed your configuration. Rebooting the computer will reinstall the network adapter. That is why it is an ideal solution when upgrading from Windows 10 to Windows 11 as this is a common failure in this situation. The steps to follow are those:

1. Tap Start.
2. Scroll down to Settings.
3. On the side, click on Network and Internet.
4. Click on Advanced network settings.
5. Choose network reset and confirm the action.
6. It is important to restart the computer immediately so that the adapter is reinstalled and check if that has solved it.
