So i have a descent cable modem connection and a router to hook my 360 and my computer to the net. everything works great. when my buddy comes over with his xbox he also hooks into my router. we play gears of war. we cannot join the same game together. to play a game together one of us must host the game. durring a game hosted by either one of us the other xbox gets disconnected from xbox live about every 3-5 minutes of play.
it may be gears of war related, or not, but thats the only game we both have cds for
Chances are because you are using the same public ip, I don’t believe live allows more than one xbox 360 to be connected via the same public ip addy but I’m not 100% sure on that… but probably more than likely what it is.
Unless they’ve changed it, you can have upwards of 3+ Xbox’s connected through one public IP address.
Try updating your router’s firmware. I remember there was a rash of this awhile ago during the days of Halo2 and R6: Black Arrow and I believe this was the fix.
