Everytime I play LoL I experience normal ping at around 70-80, but every 3 mins or so, my ping raises to 500 and stays there for about 20 seconds. This happens to me every game, and even after calling my ISP, they continually "assure" me it's not from their end. Is anyone else experiencing this? I hate that I can pretty much throw a game due to such a horrendous lag spike.
