Nighthawk AX2700/CAX30 keeps rebooting

[jonkeyes01]

Hardware:  CAX30

Firmware:  v2.2.2.2

I've owned a Nighthawk AX2700/CAX30 cable modem router for about a year.  Used at home.  There are 4 users in the home.  We don't do online gaming, but do stream TV, use wi-fi to connect to our cell phones, and have Ring Cameras.  Here is the problem:  My internet connection cuts out and my router reboots multiple times per day.  The issue first started happening every few days.  Then every day.  Now it happens probably 3-4 times per day.  My router will stop working, internets connection cuts out, and then internet starts working again after 2-3 minutes when the router reboots. 

Any idea what could be causing the problem?  Does the router keep some internal record of what is causing it to reboot?  I searched through the Nighthawk App and could not find anything explaining why the router keeps having this issue.

If the CAX doesn' sense a connection back to the ISP, it reboots. This is normal behavior for it. So it makes me suspicious of the ISP's connection. when its working, a copy of the cable connections page (shows upstream/downstream details) and the event logs help confirm this suspicion
