I have been off my xbox360 for a while and my xbox live ran out. I pluged in my xbox360 Internet cable to my router. For some reson it wont reconize my xbox360 internet wire and now I cant go on xbox live. While I was off my xbox360 for about 2-3months i got a new router. The internet cable works fine. Why wont it reconize my internet cable for my xbox360 and let me go back on xbox live?
