I have a wireless internet connection and whenever I use Steam it usually cuts off. Plus whenever I use Bit-torrent it generally cuts off too. I moved closer to my router but it still happens. I heard that there is some connectivity issues already in Ubuntu 13.04 but I never found an answer to resolve it. I heard you need this so here you go.
