I am suffering with lag on COD4, MW2 and MW3! I don't belive the lag is being casued on my side becasue I have full signal, I am the only person who is using the bandwidth I had a Ethernet cable directly plugged into the xbox with 75MB Download speed and 15MB upload speed with the Call of duty titles Portforwarded to my router. My friend and other players are also expercing the lag as well. PLEASE HELP ME?
