I have 3 xbox's in my house and my profile won't work on any of them. Everytime I try and connect it says I dont have connection to xbox live, test your connection. So I do! I connect with everything until I hit the xbox live connection bar. It takes forever and then fails. I figured maybe its the "router and modem" but no..my uncle's profile works just fine on his xbox downstairs. So i said hey!! can I try my profile down here, he said yea, no problem. I signed in and it froze the xbox....I need help because I don't know what to do. My uncle is a Microsoft employee and he believes it's the Xbox live that isn't working and not our modem and router. I believe him because his PROFILE WORKS!!
