Recently beenhaving some PSN and Live problems. At first I could not get a connection to the internet at all. I fixed that by changing a cable, but now I have been having NAT3 problems. NAT3 means the user might have restrictions on communicating and playing online with friends. I can go onine on psn, but i can't play KZII. I can log onto Live, but not into the game/video marketplace. I am not sure what to do because i have a belkin and linksys router.Maybe i'll just wait till it corrects itslef, because if it did it by itself, it might be able to correct itself.
