Playing COD Black OPS on Playstation Network problem?

rather than the PSN, or your game, it is most likely to be your connection to the internet via your router, you could have a slow internet connection which would ultimately cause you to lag and glitch around the place. you should consider looking at your current broadband package and deciding whether or not you are going your moneys worth from it. so you should look around different electronic stores and buy yourself a new router !
