The stats were all good at that snapshot in time. Are you actually experiencing any connectivity problems, or are you just focusing on the log entries ?
The signal stats were all good in your first screensot. No channels were "impaired".
And the DOCSIS 3.1 / OFDM channel was indeed locked on to. It is labled as "Other" / channel 48;
Why do you say that ? The signal stats for that channel are fine. It doesn't even show any uncorrectable errors present. Are you actually experiencing any connectivity problems, or are you just focusing on the error log entries ?? The error log entries (many times are just hypochondriac) are for the overall RF connection and are not specific to any single channel..
