As most of you probably know, Gears of War 3 is coming out tomorrow. I'm really stoked but i'm having trouble conneting my 360 to the internet. I'm at a private college where they have some security systems. But the guy across the hall cloned his Mac adress (or physical adress) from his laptop and got a perfect connection. I did it and it worked for about a half an hour then kicked me off. Now when i try and connect I either get an MTU error and it kicks me off (i have to then unplug the modem and start over) or it connects to live but then won't let me sign in. I really hope someone can help me out i need to play gears 3!
