I've lost the ability to connect to WiFi. I can hard wire with Ethernet to get internet connect. This seems to have just stopped working out of the blue. I do not see a Wireless Network Adapter in Device Manager. I do not have the WiFi option in Settings. I have tried uninstalling then reinstalling the onboard Qualcomm Atheros AR8161 Gig Ethernet controller with no luck. Any help would be appreciated.
