I've had this problem for a very long time now (1 year and running). throughout the day, the upstream power levels will spike up to the near 60s and cause extreme packet loss. During these periods, I cannot browse the internet, stream video, etc until the power levels settle down again. The modem itself will not reboot as these occurences are only around 15 seconds long, however they happen very frequently ( around over 50 times per day ).
I have an Xfinity supplied XB7 modem, and I have had a tech come over to try and resolve the issue. What's strange is on the day the tech was scheduled to come, these spikes didn't happen which was odd, and the tech said everything was ok. However, around 3 days later the spikes happened again and everything returned to the way it was. Thing's i've done to try and resolve this are: making sure there are no extra splitters in my connection, and restarting my modem several times (which did not help at all) '
Now especially is this issue annoying because I need to work from home, and an internet connection that cuts out every 15 to 30 minutes is a hindrance. Someone please help.

Over the last few months, I noticed that my ping in online games would suddenly spike and disconnect me from the game servers. I also noticed that these occurences happened in complete synchronization with when website loading times/ buffering times ould be excruciatingly slow. So, I followed the network troubleshooting guide on r/comcastxfinity and pinged several IPs such as 127.0.0.1, 10.0.0.1 and such. Everything looked fine until I pinged google.com (public IP) , where I saw several packets being lost as shown in the image. Someone please help.
I have the performance pro plan (175 down, 5 up), and an ISP provided XB6 modem/router. I have around 7 - 8 devices on at any point in the day, 2 of which are most likely gaming online, and sometimes 1 or 2 devices that are streaming video (netflix)
Edit: Image wont show so I'll just tell you whats going on when I ping google.com on the command prompt. So basically, very frequently and randomly, the prompt wil say "request timed out" a few or several times before a response appears as shown below. Sometimes even a message stating " reply from (my gateway's WAN IP) destination host unreachable" will appear.
