I have a 5.1 mbps speed and my xbox is right up to my router. My connection to games say its perfect, but yet when i play them, they lag terribly. I don;t know how it could be lagging, i have done port forwarding. Is there a way i can troubleshoot this male cow poop. (bullsh*t) Please dont put something cocky like get a PS3, I would like legit answers. Thanks!
