I'm on XBox Live using Comcast high-speed internet in Richmond, and I usually don't have any problems with disconnects on my end. It's usually the folks I'm playing against that disconnect, either intentionally or because of a poor connection. Sometimes, the action gets a little choppy, but that's usually when my wife is using the computer online... and then I
politely ask her to please stop using the computer while I'm playing Madden online.
