On some cause after waking up from sleep or hibernation the Wi-Fi adapter can not mechanically reconnect to my residence Wi-Fi entry level, and the listing of wi-fi networks is empty. If the laptop computer is restarted, Windows will mechanically connect with my Wi-Fi community and I can entry the Internet directly as traditional. The subject is kind of irritating and tiresome, since I have to restart the laptop computer a number of occasions a day (enabling/disabling Wi-Fi adapter in the Device Manager has not helped).

Restart WLAN AutoConfig Service

In my case all strategies mentioned above didn’t assist. As it turned out, the issue was associated to the WLAN AutoConfig service.

WLAN AutoConfig service is used in Windows 10 to handle all wi-fi connections (Wi-Fi and Bluetooth). It is WlanSvc that’s liable for detecting, connecting to and disconnecting from wi-fi networks and . If you cease the service, Windows received’t have the ability to see wi-fi networks and to hook up with them.

After waking up from Sleep, open the listing of providers in your pc (Win+R -> providers.msc) and discover “WLAN AutoConfig” in the listing. Make certain that it’s configured to begin mechanically. Try to restart it. In my case, I couldn’t do it. When attempting to restart/begin the service, the next message appeared in the console:

Windows couldn’t begin the WLAN AutoConfig service on Local Computer.

WlanSvc began efficiently solely after the restart of the pc. I discovered that svchost.exe of WlanSvc hangs on after hibernation. It is C:windowssystem32svchost.exe -k LocalSystemNetworkRestricted –p (you’ll be able to see this path in the service properties).

After that you could begin the WlanSvc service in the service administration console.
