Daily Dropped Internet Connection

Good morning folks. I have been having an issue with my Cox service for quite sometime. The internet will just "vanish", but the Eth0 & WiFi will continue to work fine. At first, thought it was our router, so purchased a TP-Link AX6000. Still doing the same thing. So, upgraded the router. Cox had mentioned that we would need to upgrade to a DOCSIS v3.1 anyways, so why not. Purchased the CM1000v2 and still having the same results. All the lights stay on and functioning, which is why I originally thought it was the router. Only way to fix it is to power cycle the modem and works fine for a couple days, then same issues all over again. 

I had Cox Contractor out last month, and he replaced the line from the Ped (only about 10 yards from our house) to the house. Changed the RG-6 fittings on the line that goes in to the house for approx. 5 feet to the modem, straight from the box outside that wall. 

I had to reboot the modem about an hour ago because the internet vanished again. Here are the details of what the modem connection currently looks like while running. 

We are on the Cox Gigablast Plan just FYI. Below is the Firmware Info, Connection & Event Logs.
