Netgear Cax-80 - Dynamic Range Window Violation

Hi,

My internet has been a bit spastic the last few days. I have several Nest speakers that will randomly not being connected to internet, wifi speeds will be shockingly low, streamed video might buffer, etc. Anyway, looking at the event logs, there are these warnings that the dynamic range window has a violation. I contacted chat support and the individual I was connected to simply told me he ran a diagnostic and it said my $500 wireless modem was bad and I should just lease the Cox unit. I called in then and the gentleman said he was going to push an update to the modem. I'm not sure what this is supposed to do but anyway he did it. I have a hard time believing the Netgear device is suddenly bad, so I am reaching out here for some insight.

 

This is the cable diag PRE-Modem update

If the Partial Service mode does not go away within a few hours (Click the Refresh button after each step):
1) Make sure the coaxial cable is tightly connected.
2) Remove any unnecessary splitters.
3) Replace any required ones.
4) Contact your service provider for troubleshooting help.

    This is the log subsequent to the "modem update" that the Cox rep pushed. Note, the event type 16 and 24 is a constant thing, but again, more DRW violations today.

      A lot of ranging issues, it's one of 2 things, wither there is a signal issue to the modem, OR it's possible the modem isn't properly identifying the power requirements and is having AMP issues. You have have to have a tech take readings on site to identify the issue.
