CM1000 Connectivity Issues - Dynamic Range Window Violation

My internet keeps dropping periodically for a few seconds at at time. My log shows a "Dynamic Range Window Violation" happening every three minutes, roughly. 

 

This is very annoying, and I haven't been able to track down a solution online. Please help.
