Periodic slow connection/disconnecting. Getting worse.

I am having issues where my typically fast speed service (800mbps down /19mbps up) is losing connection in games, online meetings, and other live or real-time services. Online video watching doesn't seem to suffer because it is has buffered content to service through the connection issue.

The problem used to be a few times a day maybe once a week, to now having easily 20+ interruptions/day (sometimes more). I just recently started logging it with PTRG. I don't really know how to use the application that well, but you can see my log since I installed it earlier today. 

In the attached image you can see the past 2 hours and how it usually is hovering around 200 ping and as low as 134, but will jump to 10k, 20k, or 30k everye once in a while. When that happens all of my up traffic gets really bad, my voice is robot like and breaking up, but I can hear others fine. Usually returns to normal in 10-20 seconds.

So far, I've had 2 chats with support.

1 - They said they saw a static issue on the gateway and "rebuilt" the file.

2 - Next they said they would send some reset signals and asked me to restart the router.

Each chat ends with me having to just "wait and see" because as mentioned, the issue is periodic.

Hopefully the next time I speak with support they will have a good solution for me.
