I bought the xbox 360 and i can not get onto xbox live. I use the wireless xbox router to connect to my internet. Ive tried 3 different routers and all of them were compatible with xbox live and ive tried 2 different modems and they were compatible too. Ive called microsoft, the router support companies, and my isp a million times. There is nothing wrong with the xbox because i took it to someone elses house and it worked with the internet. When i test the connection on the xbox it says MTU failed. I set the MTU to the correct setting but still doesnt work. I cant even connect when i do a direct connection from the router to the xbox. My freind down the street has the exact setup I do, linksys router with RCA modem with time warner cable for the internet. He has road runner but i have AOL, could AOL be the problem? Can you guys give me some ideas on what may be wrong or what im doing wrong and how to fix them?!?!?!?
