This system uses an injection‐locking technique to enhance the usable bandwidth by making stable channel states. Move CM’s service flows back to original BG. I am on the 100Mbps plan and in the Irmo, SC area (not sure if this is why upstream is limited to DOCSIS 3.0). Interestingly, upstream light is green (indicating DOCSIS 3.0 for upstream/send)? Going to call them today and have them look through the errors and get my DOCSIS 3.1 blue light back. Can you see it on your(Cox) side? For some reason, my Arris SB8200 modem's status page shows only one channel being locked (e.g. Pretty sure OP should have OFDM channel locked. A loss of FEC lock on one of the assigned downstream OFDM profiles of a channel.
