Instructions to fix Windows 11 wifi connection loss error

There are many causes of wifi connection failure on windows 11. Depending on the cause, there will be different solutions, specifically as follows:

Fix network security key mismatch

This error occurs when you try to connect to a Wi-Fi connection. It is likely that you recently changed the security type like WPA, WPA2, WEP, etc. Changing the security can cause this error, so you can’t connect to the network you used. In this case, you just need to re-enter the wifi password and connect again.

This is something we each do when we have connection problems. This is the first step that usually fixes any errors you may encounter. If the modem cannot update security changes automatically, you may get this error. Restart your modem and see if that fixes the problem.
I recommend restarting your PC while your router connects.
