I've had glitches for some time now. Modem log showed "Channel Change" message more than every minute. Got a tech out who noted my downstream signal was too high. Adjusted to +1 dBmV, and the channel change entries dropped to 1 every 40 minutes. Not what it used to be, but generally working. Now, a week later, I'm seeing about 1 channel change every 60 seconds.
Is this congestion from Cox? Or my decade-old Motorola Surfboard DOCSIS 2.0 modem?
