I get on battlefield 3 disc 1 (multiplayer) and I get disconnected from live. I try to sign out and then sign back in, but i says that i have lost my internet cinnection. my inernet connection is a wireless one, but I have all the updates and I can play live on COD MW3 and Forza 4, just not Battlefield 3. I have opened up all the ports xbox.com says to open, and everything else ive heard of or read. Please help me!!!
