All of a sudden my PC no longer connects via Wifi and it says no connections are available. I know the network is there because every other device in my house is connected to it. I can connect via ethernet but that's not a solution since the only router in the room is my business class router and it has to be kept only for work use. I tried reinstalling the wifi driver and I got an error message saying minimum system requirements not met. I don't know what to do...is it possible my wifi got "unplugged" somehow internally?
