Apparently my dads Modem only has 1 ethernet plug (its a Scientific Atlanta 2100) and the one it has is going from the modem to the computer, and for some reason whenever i try to connect the 360's cord from the modem to the console the IP adress always fails. Also another wierd bit, my dad also has a laptop using a wireless USB sprint card (like the ones where you can get internet anywhere) and when i connect the 360 to one of the ethernet plugs. the ip adress still fails, and it doesnt show a DNS on the console or the computer. Any help please? I want to download castle crashers so badly tonight.
