Have you tried bypassing the router and connecting via ethernet direct to the CM1100 modem? Does the modem logs timestamps match up with when you lose service? The only critical warning I see is the last one. UCD stands for Upstream Channel Descriptor so it appears a issue with the upstream. Most of the errors are event error 16/24 which is on/off issues with the first downstream OFDM channel. I think those are "normal". The Dynamic Range Window Violation is usually paired with a T3 error(which is a upstream noise issue) so I think your issue is defiantly upstream.
While it could be a modem issue, my experience is it is rarely that. If you do buy a new modem make sure it is returnable if it doesn't solve the problem. Otherwise, try tracking the packet loss with Pingplotter and schedule another technician.
