I have AT&T DSL internet. I am trying to go wireless evrywhere else in house. I had DSL wired to Linksys router then wired to PC. then PC adapter in PC up stairs and a laptop wireless installed. This systems worked fine for a few months then the internet would drop and i would have to wire DSL directly to PC to get internet back. Now i cannot use Linksys at all. is it the AT&T software or something else??
