Netgear CM1000 Critical errors in logs and constant reboots.

I bought two CM1000 modems due to cox support telling me the first one was defective. The issue I had was the modem would only stay connected for 30 seconds, then reboot. Unfortunately support refused to help me beyond telling me to buy a new one as its probably defective, and if that wasn't it, to call Netgear. which I highly doubt they have anything to do with it. My previous modem is a cm700 and it at least only has a few dropped packets here and there.

The log follows.
