Internet Connection Drops Intermittently

I've been experiencing issues where my internet will drop for about 30 seconds at a time, multiple times a day. When I log into my modem (Netgear CM700), there are a lot of error messages and it seems like the problem may be somewhere between Xfinity and my modem. Everything was working great until recently, maybe the past 2 or 3 months. Can anyone help me with this?

There are no splitters between the Xfinity box and my modem.

The cable from the box to my modem appears to be in good condition with tight connections.
