CAX80 keeps rebooting

For the past 3 days my CAX80 has been rebooting every 4 to 5 hours. I’ve tried connecting the power source directly to an outlet and that didn’t work. I did a factory reset and that also didn’t work. ...

I would be concerned about the CPU usage being that high. Wow. 

Are you seeing this all the time on the modem?

-> @2-days up and counting...

-> I still do not see the "A Router Firmware Update is Available" banner

 

-> The [DoS attack] LAND Attack SPT:2190 DPT:2190  Log messages are back at intervals ranging from ~1 to ~10 minutes apart. The  source IP Address "xx.xxx.xxx.xx" is my ISP assigned WAN IP Address which as someone previously mentioned, is very strange as it looks like a "Suicide" DoS Attack. My ISP is Spectrum.

FURRYe38... No, my CPU utilization is normally not that high. That screenshot was probably taken when my two  NASes were syncing the previous day data. This usually happens overnight after 1am, but because of the router reboots I had to recently rescheduled the sync to 7am.
