New CM205V Interferes with TV Signal
When a CM2050V is connected to a three-way coax splitter (the modem, and two TVs to Xfinity Voice/Data/Cable television service, it disrupts the signal to the two tvs. Disconnect it, and the TVs are...
Way too many correctable/uncorrectable errors for a 24 hour period of time.
DOCSIS 3.1 is backward compatible with DOCSIS 3.0. I do not think DOCSIS 3.1 is backward compatible with DOCSIS 2.0. If you are looking at DOCSIS 2.0 hardware, you want to check the coax type to ensure it is correct for the current DOCSIS 3.1 connections (RG6).
What were the upload/download throughputs with your new splitters in place?
You might find some ideas in chapter 3 of this reference: https://www.duckware.com/tech/solving-intermittent-cable-modem-issues.html
New splitters cleaned things up but still had problems with occasional pixilation and anomalies in ever-changing areas of the screen. Rolled back to the old modem, things back to normal again. Report attached. Somehow this modem is not compatible with my system. Maybe it's the DOCSIS 2.0 cable boxes I use. Maybe it's something else. Couldn't get the new cable box to respond to the IR emitter connected to a legacy universal remote system, so that's not an option at present. Internet speeds are the same on the new and old modem. Thanks to all for your time and effort.
For both, power levels are good now for both, however both modems are seeing too many Correctables and Un-correctables.
The C series is DOCSIS 3.0 and the CM is 3.1.
Something maybe happening down the line after the modem.
