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
Typos in title and post. CM2050V. Xfinity, formerly known as Comcast. Splitters work with C7100V. I'll give it a try in the next week, but I have my doubts. Why would the new modem require a new splitter? And why would an old splitter interfere with the cable TV signal only on the new modem??

Your new modem will connect to the Xfinity Enhanced Speed Network that runs up to 1 GHz. Your old modem would only connect to the Xfinity standard network that peaked at around 850 MHz. Your old splitter is blocking part of the spectrum your new modem is trying to work with and causing problems.
No need to waste $ on new splitters that are capable of going above 1 to 1.1 GHz.
Very helpful explanation. Will try it again next week with new splitters. Thanks.
Try removing all splitters first, and check for correctables and such, if zeros, then you'll know.
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. Reports 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. Back everything goes for now. Thanks again for your time and effort.
Here's the C7100V report.
