sb8200 technical issues

Xfinity 400Mbps "blast" service but I'm only getting 30Mbps down (am getting 10Mbps up as advertised); I've seen several other posts but no firm resolution; modem sporadically shows the "blue" Docsis 3.1 light for download but mostly shows green. Will post status and error logs below.

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.
