Packet loss

Hi,

I've done extensive testing of the ping jitter, and isolated it beyond my equipment. I am getting anywhere from 1-30ms round trip ping from my access point or router, but when I track my ping beyond my router, it has consistent spikes of ping up into the 130ms range.

This makes games unplayable.

I’ve done a few test and I have the ip addresses that are causing the packet loss and they’re all from comcast. Please help.
