I was wondering if its worthwhile me upgrading my Cat cable? I don't know very much about networking etc, and i get lag online on certain games, even with the Xbox 360. Ive got a belkin ADSL 2+ MIMO 54Mbps, im using the standard cable, im just wondering if a swap to a Cat 6 might do the trick? Just need some info before i go out n spend some money, can anyone recommend a good cable? Im eyeing up a belkin Cat 6 cable from PC World. Cheers. dan.
