Okay, so a month ago I got AT&T U-Verse internet: 12Mb/s downstream and about .98Mb/s up. For the first two weeks of service, everything ran fine. Then a little over two weeks ago stuff just went nuts. I am experiencing lag so bad that I literally can't hope to play really anything online. I play a ton of BF3 online and the issue as it appears while playing that game is me running through a map and, for no reason (no obstacles in the way) I run in place for about a second then start moving again. That also lasts for only about a second because I am then teleported backwards to the spot where I just lagged and ran in place at. It's the most infuriating problem I've ever experienced in the many years I've been gaming online. Whether I'm driving a vehicle, firing my weapon, or just walking around, this problem is rampant and happens anywhere from 1-10 times a minute. People I play say that on their screen, when I'm having the issue, I'm just running in place. This same problem occurs when I play any game, Call of Duty as another example. I'm playing on an old Pro model 360 with the original white wireless network adapter. Gateway is only about 15 feet away.
