I am a new user to Ubuntu. My Wifi was working fine with Ubuntu. But suddenly it stopped working and my laptop is not able to detect my router. When I switch over to Windows, it works fine.
So the only problem I could think of is with the Driver. Would re-installing my driver solve the problem? If so, how should I do this with Ubuntu? Please be elaborate as I am a relatively new user.
PS: My version of Ubuntu is 12.10.
