AT&T announced a few months ago that they were going to cap DSL users at 150 GBs. My household and workplace share the same internet source. My office is a couple hundred feet from my house and we are going to blast the signal via Cantenna over the entire house ( currently only 1 room gets signal). My son likes to game online (Ex: TF2, L4D,Garry's Mod, etc) using Steam. With AT&Fee incorporating these caps, how much of the allotted amount are these Games going to use? He plays for about an hour or so a day, sometimes more. Do you think this will be a problem?
