Picked up MW2 and can't seem to stay connected online. I have my modem connected directly into the xbox (no router.) It will connect when I sign into xbl and then kick me off after 5 minutes, then when I test the connection it says everything is fine so I sign in and get kicked again. Called my ISP and did a speed test with my laptop in the same room and the speed is good. Then call xbox and they say it must be a problem with my connection. I played online a week ago and everything was cool. I still can't play MW online. Anyone ever heard of this?
