Alright I have had this problem for a long time now and its really starting to make me mad. When i try to play any of my games online now my xbox decides to lag so bad that I can't even play. this has only been a problem recently. I tried to figure out why my connection was so bad and why my games lagged so much online. So I decided to check my internet connection because thats usually the problem. In this case its not. I do run a wireless adapter and I bought a new one thinking that was the problem but no it wasn't. Then I decided to take my xbox into the same room as my wireless access point, but the result was still **** lag. Another thing to mention is that my brother who also runs a wireless adapter on his xbox on the same internet connection doesn't experience any lag when he plays. So I decided to play my games on my xbox in the same place but it was still laggy. then I played my games on his different xbox in the same spot and voila! perfect online game play. So I think there is something wrong with my actual xbox which is causing this issue if any of you guys could shed some light on this i would greatly appreciate it!
