How to Fix Wi-Fi Keeps Disconnecting on Windows 11 (Solved)

The Internet on my laptop used to be reliable and stable before I upgraded it to Windows 11. But after that, there were many moments when the WiFi kept disconnecting on Windows 11.

This issue happened with the two Windows 11 laptops at my home, and a quick search on Google led me to find out that this is a common issue for many Windows 11 users like me.

(If you have an Intel WiFi 6 AX201 network adapter and your WiFi keeps disconnecting, I’ve written an article on how to fix Intel WiFi 6 AX201 keeps disconnecting.)

Here is how to fix it on the command prompt (all the commands below are safe):

1. Enter command prompt in the Start Menu and run it as administrator:
   
2. On the command prompt, run the following command:
   Netsh int ip reset c:\resetlog.txt
   
   The reset command resets the TCP/IP by rewriting two registry keys (SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ SYSTEM\CurrentControlSet\Services\DHCP\Parameters\) that are commonly used by TCP/IP to restore the TCP/IP protocol to default.
3. After resetting the TCP/IP, input the command:
   Netsh winsock reset

   This will help your PC recover from any socket errors that arise from spyware or web browser hijacking corrupting your settings.
4. Then finally, input this command and press Enter:
   ipconfig /flushdns
   
   Flushing DNS will clear all the DNS records from your cache. This should be done from time to time as it helps improve security and your internet connection.
5. Restart your PC

(If you have slow WiFi issues on a Dell Inspiron or slow Wi-FI on Asus laptops, read the articles I’ve written specifically about this.)

If the problem persists, try the method below to reset your network settings:

How to Reset Network Settings on Windows

In this step, we will run the network reset to remove any network adapters you have installed alongside their settings. Then we will restart your PC so that it reinstalls any network adapter and restore its settings to default.

This is important to fix any corrupted settings on your network, which might have been caused by malware or browser hijacking. To reset your network settings:

1. Enter Settings in the Start Menu and click on it:
   
2. Click on the hamburger icon on the top of the Settings window, and then select Network & Internet on the left sidebar:
   
3. Browse down and click on Advanced Network Settings:
   
4. Under more settings, click on Network reset:
   
5. On Network reset, click on the Reset Now button and select Yes to confirm:
   
6. Restart your PC

If this doesn’t solve your Wi-Fi connectivity issues on Windows 11, try the fix below.

Updating your Network Adapter Driver on Windows 11

There are two methods to manually update your network adapter driver on Windows 11. One is using a third-party app like Driver Booster, and the other is through Windows Device Manager.

You should use Driver Booster to update your network adapter driver because it contains the latest drivers and allows you to do a driver backup before installing it (to restore your older driver if any problem happens).

But if you prefer to do it without a program, I will also show you how to do it with Device Manager.

Updating your Network Adapter Driver with Driver Booster

1. Download Driver Booster and install it on your PC.
   (Remember to unmark any checkboxes with bundle offers if you prefer not to install other software.)
2. Open Driver Booster and click on the Scan button:
   
   Now, wait while the program scans for all outdated drivers on your PC.
   3. Now find Network adapters on your outdated device drivers list, and click on the Update button next to it:
   
   You can also click on Update All to update all your drivers at once.
   4. Now confirm and wait for the update to finish.

How to Update your Network Adapter Driver on Windows 11 Device Manager

1. Search for Device Manager on the Start Menu and click on it:
   
2. On the Device Manager, expand Network Adapters to find your network adapter.
3. Right-click on it and click on Update Driver.
   
4. Click on Search automatically for drivers:
   

This should fix your connectivity issues on Windows 11.

Conclusion

To fix any WiFi connectivity issues on Windows 11, you want to take these three steps in order:

1. Reset your TCP/IP, reset Winsock and flush your DNS cache on the command prompt.
2. If the first solution didn’t work, reset your network settings on Windows 11 settings.
3. If the second solution doesn’t work, update your network adapter drivers.

Only update your network adapter drivers if your Internet has WiFi issues. If the other solutions have already worked, you don’t need to update your network drivers.

Besides all the solutions discussed in this topic, remember to keep your Windows updated, as Microsoft will fix the current issues with later updates.
