There are various reasons your Windows 11 PC might lose Wi-Fi connectivity, and you can fix most of them yourself
Try restarting your PC, running the built-in internet connection troubleshooter, or enabling the Wi-Fi adapter in network connections, as it may have been disabled
The option to find this is Control Panel > Network and Internet > Network and Sharing Center > Change adapter settings
You can also try enabling the WLAN Auto Config service, updating the network adapter drivers, or configuring the network adapter power management settings
If you’ve recently updated Windows, try reinstalling the Wi-Fi device driver, or perform a network reset, which will reset all network adapters and other networking components
If these do not work, you may need to contact technical support or replace your Wi-Fi card or dongle if it is faulty
