Windows 11 WiFi keeps disconnecting randomly

Can you try deleting the WiFi profile and then reconnect it.

Also, try this:

1. Open Device Manager.
2. Locate WiFi driver, right click, select Properties.
3. Go to Power Management tab.
4. Uncheck 'Allow the computer to turn off this device to save power' option.

If issue still persists, you can attempt Network Reset once.
