Hey guys, I experienced this issue in the past. I used to be in the middle of a game of COD4 online, and during the game periodically my modem would semi-restart itself. The Power, DS, and US would stay on and everything else would shut off. 5 seconds later, I'd still be in the game, the lights would come back on and I'd be fine, almost like a super huge lag spike. I contacted Comcast support, and they dispatched a technician whom provided me another Motorola Surfboard Modem w/ Phone (Since I get my phone through their service as well). I really haven't played COD4 much since then and have been focusing back on World of Warcraft. Saturday, I was playing in a 25-man raid (also with Ventrilo running) and quite a few times, the modem began to do the same thing. I have yet to contact Comcast regarding this issue reoccurring again. It's been awhile since I've done the 25-man raids, so I don't know if it only happens during then or what. I know that I haven't had the issue during the 10-mans, and I haven't noticed anything else causing this to happen. Also, my girlfriend was playing WoW and on Ventrilo at this time as I was watching these problems happen, and I nothing else besides WoW and Vent were taking up bandwidth. Does anyone else have similar problems? Is this a hardware issue with the modem, or is Comcast in fact limiting my bandwidth usage this way? As much as I don't want to do this as it may affect other users, is there perhaps a bandwidth stress test to be run to see if high modem usage causes this, to force the issue?
