Recently I have been trying to play COD multiplayer and my ping has been jumping around like mexican jumping beans. From down to 30 and up to 700. This is totally killing me (literally). Before I was able to play with no problems but for some reason something has been F-ing it up. I currently attend the University of Tennessee and I use their connection, it was fine in the beginning but not now,I guess. I have no programs running other than what is needed, xp firewall turned off, nothing else should be blocking it up. Also my comp is well above the system requirements. So what could be the problem, please help.
