Not receiving DOCSIS 3.1
Up until last week my ARRIS SB8200 was receiving DOCSIS 3.1, indicated by the blue lights on the front of the modem. Directly wired in I was pulling 900-940 mbps down. Those lights are now lit green, representing DOCSIS 3.0, and I’m now limited to 500-550 mbps. I’ve tried numerous resets and even bought a second SB8200 to test, same issue
I have had no changes to the coax line and I am not using a splitter. Looking for suggestions, hoping to avoid the $75 charge to have someone out to my home if at all possible.
