Your logs are still indicating line issues. The dynamic range window violation is the power level going out of spec. And you've got other errors indicative of line issues. It can get complicated with line issues. And replacing the line doesn't always fix the issue as it could be a hub, loose connector at the pole, etc. You can read through this users difficulty with it.

What I've done and seen users do is rent the xfinity modem for a month. its like $15 or something. If it has issues, it means they can't blame your "third party modem". So that only leaves the line/hub/connections. And puts them responsible for fixing it. If it does fix the problem, its proof the cm3000 has issues
Thanks!
I'm returning the modem since today it my last day to return it back to Amazon.
I going to do just that. Rent a modem and/or see if I can switch to ATT as a backup plan.
Line drops I can't deal with for long. They replaced the line and had someone came out again to confirm it and run tests.
Thanks for all your help and prompt response!
