i've had no issues up until about 3/4 days ago when all of a sudden I started experiencing extreme lag when playing online or trying to watch the sky player.
sky player buffers every few seconds (even on the lowest quality) & i've been unable to play Fifa11 or Call of Duty online without getting kicked out almost immediately.
