signal issues cable modem

My modem is consistently showing issues isolated to two downstream channels.
Channel ID 42 is accumulating uncorrectable errors rapidly, and Channel ID 43 is accumulating corrected errors at a much higher rate than all other channels.
Every other downstream channel remains clean and stable, and my upstream levels are normal.
I’m connected directly from the wall to the modem, so this isn’t an inside‑wiring issue.
It appears to be a localized impairment affecting only those two channels.
Could you check the line on your side to verify signal quality for those channel IDs?
