Open a command prompt and type netsh wlan show networks do you get a list of available networks?
Also open regedit navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkUxManager\Windows.Networking.UX.Internal.WlanMediaManager
Validate there is a property called Active of type REG_DWORD if it is set to 0, change it to 1 and see if you can see networks.
