I dont know whats happening. It was fine yesterday but today, i kept on lagging out of cod4...I also dced from XBL randomly while i was on the dashboard. When I ran the network test, it said i have a "Medium NAT" idk. I just power cycled my router and modem then it was fixed. I dont know whats the problem though cause its still happening. I have a Motorola SB5120 modem a linksys WRT54GL router and an xbox wireless network adapter. my IP is comcast
