RCS Partial service and Sync Timing Failure. Please Help Arris SBG 7400AC2

Can someone please help i get hit wit the RCS Partial Service and then the Sync Timing failure once or twice a miniute.  Its making my Internet really intermittent.

I have a Arris SBG7400AC2

I have 24 Downstream Channels but it looks like its only using 16.  Should I be worried?

Is it a Modem problem, or something on the ISP end?
