some times it is because the low strenght of the signal.
but now i placed my xbox where it can play youtube on hd with out any problem.
but the other day i had my xbox next to the router, and tried to play "Guardians of middle earth", and the match was so laggy it was unplayeable....
so i want to know if is my router fault, or litteraly the wifi was never intented to be a playeable resource?
