Another upstream packet loss problem...

After several years of great Gigablast service, I have been having some extreme packet loss that started around 12/6 in New Orleans, LA that is constant and interrupting video calls/voip services/gaming/remote access/etc. Cox support through chat is telling me that I need their $13/month panoramic wifi modem to fix my issues! Things I have tried already:
1. power cycle modem
2. reset modem through cox app
3. bypassed router completely and plugged a laptop directly into the modem with same results
4. Checked to make sure all f-connectors on rg6 are tight (no splitters on line at all - direct connect outside)

I am hoping there are some next level Cox techs in here that can help?

I am going to attach pictures of some pingplotter screenshots to 1.1.1.1 and 8.8.8.8.

DL speed are fine, UL speeds are poor...

Any help would be greatly appreciated!

    What model modem do you have? Can you post the signal levels from 192.168.100.1? Also, any T3 errors in the logs?

      Its a Motorola MB8600. I'll post signal levels now. Unfortunately I just power cycled my modem and the log cleared, so I will have to check later to see if there are any T3 errors.https://imgur.com/a/2ZOfOmU

        I recognize those signal levels. Did you post on Reddit? Either way you have issues in the 700Mhz range. Some kind of noise.

    Based on those plots, The first step is replace the modem, because that second hop is the first one to Cox. So either the modem is bad, or you have a line issue. If you have the same issue with the different modem, then yes, a tech is in order.

        The MB series isn't a real Motorola, it's ZOOM, and certainly not a modem i would use.
