Im having issues with comcast after outside the router and i dont know what to do

ok so xfinity just isnt working for this image, but what's happening is the connection outside the router is having extreme issues that are intermittent. So much so that i cant get into contact with comcast before the internet normalizes back to its original state. I'm getting ping spikes network wide and i know it's not a computer issue. With ping plotter im seeing that the connection is breaking after the ip 96.230.0.13 and im not sure if there's anything that i can do to try and get help with the issue.
