Intermittent packet loss for months

I have been having issues with packet loss for several months now. I will get loss every 5-20 minutes that lasts for about 30-60 seconds before returning to normal. The length and frequency of the packet loss can change but this is the average that I have noticed. It can occurs on all days of the week and at all times of the day. I have called tech support and used the online chat multiple times without success. They keep telling me that the modem is likely bad. The modem is new within the past 5 months. I rented a cox modem and I am still having the issues. I have been told that the tech support agents are only able to run packet loss tests for about 20 seconds. I can't imagine that it is hard to run the test for a longer length of time. A tech has come out within the past 5 months and made sure that the cabling on the outside of the house was up to date. He was unable to come inside due to COVID. I was able to assist him with testing some of the inside wiring by connecting a tool onto the coax jack in the outlet the modem uses. He said nothing was wrong with the wiring in the house.

I am hoping for some assistance on this. Calling in to support is not helping because timing the packet loss occurrence with the techs running the test seems impossible.

This is what the packet loss looks like when it occurs.

    I should note that the device I am running the test from is hard-wired.
