I'm getting sporadic errors on channels 1-31 and tons of correctable codewords on OFDM channel. It makes for packet loss and slow loading of websites.

DOCSIS 3.1 allows for Forward Error Correction. As long as the codewords are correctable it isn't a problem. I suspect something else is going on as far as slow loading of websites. Tried clearing your browser or DNS cache, running a ping or traceroute, other troubleshooting methods?

FWIW, there is a known glitch with some makes / models of modem's firmware where the measuring mechanism incorrectly reads the power level, the SNR, and the bit errors for that channel. So it reads many errors when there really aren't.
