My Vaio netbook has stopped detecting wifi. I checked the device manager and tried uninstalling Atheros ethernet controller and restarting the computer so that it would re-install again but it didnt work.
Under that on Device Manager, I have 2 other network adapters both for Bluetooth and nothing more.
Under that, there's an unknown device listed. I tried looking into it properties and it said that the drivers are not installed in that device. I tried updating it but no drivers can be found. I dont know if this is significant or not.

Also, I tried troubleshooting but it just says that the ethernet cable may be broken or unplugged, not talking about the wifi connection at all.

What should I do?
