Internet drop several times a day, soft reboot, ongoing issue

I have already had a tech come out and check all the connections and they are coming back again a few days later because the issue is not resolved.

I have a Netgear cm2500 modem, brand new, which replaced my previous CM 2500 modem that was under 2 years old in hopes to resolve this issue. 

All of the errors on the modem seem to be related to not being able to communicate with Xfinity periodically and causes a soft reboot, which then causes me to lose connection with applications or calls with my job. Any advice for what I can do on my side or what team I need to speak to at Xfinity to get this resolved hopefully.
