Hi, I just got a new internet from Comcast, my results on speedtest.net are
Ping: 9ms / Download speed: 25mbps / Upload speed: 3mbps
But my results on pingtest.net says that I have over 100+ ping and very high jitter. I'm playing online on my PS3 and playing with a higher ping than 100 takes a long time to find games and hard lag. Any help will be greatly appreciated :]
