Nighthawk c7000v2 Dropping Connection
I have cox and they keep telling me to contact Netgear. The firmware version I am running on is V1.03.01. Below are screen shots to my event log and cable connection. Is anyone able to tell me if this is a line problem?
The coax from router to wall is RG-6 with no apparent kinks or bad connection. The connection worked fine for about a year up until recently. Any help at all would be greatly appreciated!

Yes, Any Criticals, Errors or Warnings seen in the Event logs are a line issue that the ISP needs to review and resolve.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

Thank you for your reply! I'm using an RG6 coax with no apparent kinks or bad connections. I've also tried several different coax cords, and I'm getting the same issue, so I think I can rule that out.
As far as splitters go, below is a picture of the cable feed in my house. You can see a splitter is taking the feed from outside and connecting it to 1) the main coax outlet in my office (this is where my modem is) and 2) An apparent power source. I'm not sure what the power source is being used for. Perhaps you know? If I remove the splitter, that power source will be eliminated. If the power source isn't needed, I could use a coax bridge to connect the outside cord to the one running into my office. Unfortunately, there is no ethernet outlet in that cable box, so I cannot put my modem/router in there.
In another picture, you'll see a random switch that sits above my keys. When I flip that switch, nothing noticeable happens. Could this have any impact on anything? I know it's a long shot, but I figured I would at least ask.
I tried powering off my modem and 1 minute and also tried a factory reset (twice now).
Lastly, my modem used to sit in my living room. I have since switched the ISP feed to go into my office with the hopes that solved the problem. The internet froze for about 30 seconds earlier, but significantly less time than it did when it was in the living room.
That power source looks like a amplifier/booster for something. But it runs to a splitter, not an amplifier.
If nothing else is connected to that coax line, remove that power source and just direct connect the 2 cables together.
might clean up the line quite a bit.
Something is in the line causing issues.
Reason why is the value of your upstream would mean you're right next to a hub. But your downstream values indicated your not that close. So something in there is acting as an attenuator but not doing that great a job because you're getting dynamic range window violations. Those violations mean you're power is going out of spec.
So if you have a signal attenuator or amplifier in line, remove them and recheck
