Basically this issue started a week ago. While im playing games like battefield 3 left 4 dead 2 or minecraft i get rubberbanding lag which is basically my game character running foward then being shot back to his original postion. I originally was using a wireless usb adapter so i blamed it for the cause of the lag. (My pings were fine btw) I went to ethernet for a week and the lag went away so everything is fine via ethernet. I just bought a new wireless card but there is still this terrible lag! Im wondering why this would happen is it my router? or possibly the modem? i really dont know and am honestly very confused.
