My friend got a new shape 360 and tried to get on xbox live. It tells him to do the latest update...when he does it gets right to the last part and then an error code comes up (which I will add later) but it changes everytime. He reset the router and it finally went through. It started downloading the new update but then did the exact same thing. He has 2 brothers who are using the same router with 2 different xbox 360's (old shape) so why is it saying he cant connect?
Dont tell me port forwarding please because its working with the other 2 xbox's which are both being ran wireless aswell.
