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 :]
Try power cycling your router, allow it to reconnect and give it a try.
If you see that the connection quality is not as good as it should you may have too much noise. If that is the case you should contact your ISP and have them check your line. They may need to lower your connection speed a couple Mbps but it will give you a better quality connection overall.
