I suspect it has to do with the weather changing. I’d get a technician out to see if they can isolate the errors (Forward error correction or FEC) as coming from within your home or from cox’s network outside. If it’s from outside, the weather shift may have caused some amplifiers to lose unity gain which will cause bit errors.
According to one of our resident experts, Profile ID: 0 in your log is a problem and when your connection recovers, it remains Profile ID: 0. You may have bursts of noise somewhere on the Cox network and its getting worst.
