I believe I saw something you posted on another forum, and Darkatt offering the same statement. Glad to have your help.

I don't see any way to embed a screenshot. I might be able to save to OneDrive and post a link but I've never tried that on an open forum before. Best I can do at the moment is what you see below.

Only Channel 33 is an issue which is OFDM PLC.

All other channels have no correctable or uncorrectable errors in the last 24 hours.

There are about 43 0million correctable errors on Channel 33 in the last 36 hours, no uncorrectable errors. They climb at an astonishing rate.

As you may be able to tell, signal is 10.8 dBmV, SNR is 45.1.

Everything looks great, except this one signaling channel. Just trying to figure out what the "root cause" is. Motorola and Cox not quite aligned on the codec?

      You're welcome.  You learned in 11 minutes what took some of us a couple of months.

    That handful of errors on 5/6/7 happened immediately after rebooting and nothing since.
