If you stop the service, Windows won’t be able to see wireless networks and to connect to them.Īfter waking up from Sleep, open the list of services on your computer ( Win+R -> services.msc) and find “WLAN AutoConfig” in the list. It is WlanSvc that is responsible for detecting, connecting to and disconnecting from wireless networks and creating a software access point (Hotspot) on Windows. WLAN AutoConfig service is used in Windows 10 to manage all wireless connections (Wi-Fi and Bluetooth). As it turned out, the problem was related to the WLAN AutoConfig service.

If the problem with the disconnection from your Wi-Fi network had appeared suddenly, Windows may have automatically updated the driver of your Wi-Fi adapter recently. Prior to moving to the next method, try to download and install the latest version for your Wi-Fi adapter drivers from the vendors’s website.
