High Packet Loss Making Network Unusable For Gaming, Zoom, etc. Intermittently and Randomly

Greetings Guys,

This has gone on for some time now, and I've kind of just dealt with it but the wife and myself are becoming beyond frustrated.  I'm not the most tech savvy, but I'll provide any data I can.  Essentially there are massive spikes in packet loss, jitter, etc.  which happens multiple times per hour.  We've triple checked the connections, have new hardware, firmware updates, etc.

Here is the information I can gather thus far.  It happens so frequently I can just run 10 second tests to demonstrate :)  We pay ~$200 a month for this "service" of 1,000 down/40 up but it's typically more 800 down (which is fine) and .5 upload.

here is the upstream/downstream (it appears normal to my layman's eyes)

Any help would be appreciated due to the monopolistic nature of xfinity we have no reasonable alternatives :)
