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.
Gigablast download speeds are below 300 Mbps
My Cox Gigablast download speeds with Ethernet and Wifi are below 300 Mbps. I am using Cox Panoramic modem/router. The technician checked the cable routing inside/outside the house and found no issue. He tried replacing it with another modem. But there is no improvement in download speed. Could you help to resolve this?

COVID-19, Slow Speeds, and Why You Are Paying Full Price for Them!
COVID-19 is clearly slowing down many of Cox’s servers due to the increase of Residential use across the nation. Many more people are at home and needing to use the internet for very demanding virtual tasks to replace going to work. Gaming has also increased substantially with schools and colleges around the nation closing. This is throttling your internet speeds drastically as we speak! Why are we still paying full price for our service then? Follow this link to submit an informal complaint to the FCC for Cox’s unwillingness to reimburse their customers for paying for full price speeds, while realistically receiving fractions of the speed! https://consumercomplaints.fcc.gov/hc/en-us For example I have the Ultimate package at 300 mbps, and currently I am receiving anywhere from 5 kbps to 20 mbps!
Downstream crawling / Upstream still fast
Hello - I have been having an issue with my connection for the past 2-3 weeks. I pay for 300mbps down / 30mbps up and have had no issues until now. I am getting between <1mpbs to around 7mbps down at best. Unacceptable. I used to regularly get 300mb down and sometimes even faster at non-peak times. I've done all the troubleshooting COX suggested and now they want me to change out my cable modem as a troubleshooting step and (of course) recommend I rent the modem from them. No thanks. I'd rather pay for my own and not give another $10-$15 per month to Cox. My question is this: how can the problem be the modem if it is still capable of providing the advertised upstream speed? I have made no changes to the topology. Here are my modem's stats (below) if it helps. I don't know how to read them, so maybe someone here with more experience can tell me where the problem lies. Thanks, all!
