OK im sure there are tons of these threads on this forum but I have done everything most of them say and nothing works for me! I can pass the Xbox live test conection and I connect to xbox live but then it disconnects quickly... There is no problem if I connect the xbox directly to the modem. I have no idea whats going on. I have tried lots of different types of settings, even DMZ. I dont know what else to do.
