CAX80 keeps rebooting

In my case, the "source IP" is different from my Modem's IP and is the IP of my ISP (COX Internet). I've spent all week working with them on this and they're unsure what's going on. I've done full resets of the CAX80 (I've tried updating manually from files and from the NG server), COX came out and checked every cable and line and had no issues they could find, and COX has stated they're not seeing anything abnormal on their end.

It is worth noting that the reboots have stopped for me, my current uptime is now at 6 days, so some improvement. and I can now set up my reboots schedule again. Though I'm still getting those LAND attacks. The last 2 notices in the log had 25 reported 20 minutes before this write-up, and I had another one pop up while I was in the midst of writing this.

As additional troubleshooting, I've disconnected every single device from my network and still had these LAND attacks appear (disconnected everything but my wired PC, verified nothing was connected except the wired PC, unhooked wired PC, left house, came home hours later to find dozens of LAND attacks when nothing was connected to the network), so it's not any devices in my network causing it.
