Have you gotten any progress on your problems? Im having the same thing happening with a CM1200 modem. T3, T4 errors, SYNC failure, Dynamic range etc etc. 2 Different techs said it was my modem and everything else looks great on their end.

I am trying one of xfinitys X7 modems in bridge mode free of charge for a month. So far its been better with only minimal signal loss and packet loss. They were saying it was my router first, then my modem.
