Rerouting occuring causing random disconnects from VPN

Since the problem arose, I have done all the things one would do to eliminate equipment failure. In tracking my latency, I have found that the baseline ping changes from before and after each disconnect. From a streaming/video game perspective the VPN seems to disconnect when the latency spikes too high during these reroutes. Otherwise, I simply experience a brief stop in downloading or rubber banding in the video game. Each reroute is causing anywhere from 3 to 20 seconds of latency. During peak hours when these disconnects/reroutes are regularly changing, the VPN offers a faster latency than not as comcast is routing me all over the country for some connections and not for others. I am by no means a network engineer but I can only assume that this poor service is due to the routing of the first 4-7 hops of my connection. Is there anything I can do to get this fixed because the quality of the connection is just simply intolerable? The last thing I need is a tech to show up to my house and shrug saying there's nothing they can find wrong again.
