I have a 360 now, but i cant seem to get this damn live working. this happend ot me with my ps3 and XBL before.
I have a Dlink DI-624 wireless router. Im using a wired connection. Everything works perfectly when when i test the connection except for NAT. when it reaches NAT, it says network adaptor disconnected. I also noticed when this happens, my internet on my computer loses connectivity for a while then goes back up.
I called dlink and opend up these ports microsoft told me:
UDP - 88
UDP - 3074
TCP - 3074
and it still doesnt work! I have searched this on google, but I just wanted to see what you guys have to say about this.
