Arris SB8200 Docsis 3.1 GigaBlast No Blue Lights Up or Down
Called Cox for new internet options. Told me I was grandfathered in at 150. Quoted me 300 and Giga. Call ended. I had a Netgear 3.0 modem / router combo that worked fine. I buy a 3.0 modem and a mesh router to increase my WIFI area. I try to get it calibrated only to find out I have a work order for GigaBlast speeds and my 3.0 equipment is unusable. So as a patient person I go and swap my 3.0 for a 3.1 modem costing me more money. I call to get the 3.1 calibrated by Cox and it shows all green lights 3.0, no blue lights for Arris SB8200 Docsis 3.1 GigaBlast No Blue Lights Up or Down. Speeds are 250 down and 20 up and that is before and after a modem factory reset with ONLY my laptop plugged in. Tried with a desktop as well with the same result. - Called and asked was GiagBlast and Docsis 3.1 avilable in my area and told it was - Forced to GigaBlast without request and told I can't return to my original speed - Asked me to upgrade my equipment to take advantage of GigaBlast but when equipment is installed it I only get 3.0 and low speeds - Called from 10am to Midnight and text chat too. After dealing with 6 different people and a whole day wasted I still got nowhere - Best of all I was told no work could be done while there was an "outage" in my area. One that lasted from 2pm to 7pm, and then another that started at 12am forecast to end at 6am. Anybody else have these issues and if so how were they resolved??? - Do yourself a favor and DO NOT, I repeat DO NOT engage in the text chat option from your phone. A waste of time and resources!!!! Similar situations like mine so I know I am not alone when it comes to the level of customer service andtechnical support https://forums.cox.com/forum_home/internet_forum/f/internet-forum/22627/gigablast-activation/86619#86619 https://forums.cox.com/forum_home/internet_forum/f/internet-forum/20283/issues-with-gigablast Standard Specification Compliant Docsis 3.1 Hardware Version 4 Software Version D31CM-PEREGRINE-1.1.1.0-GA-14-NOSH Connection The status listed show the connection state of the cable modem.

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.
Cox system won't "let" techs schedule service call to remove old filter, so no docsis 3.1
Hi, I recently upgraded to a DOCSIS 3.1 modem and Gigablast and I have what is pretty clearly the textbook problem where an old analog filter on the line blocks channels below about 600MHz, preventing DOCSIS 3.1 from fully working and limiting my speeds to ~600mbps. I can log into the modem's built-in spectrum analyzer and see that I have great signal down to 600MHz, where it abruptly drops off. The modem status page indicates I am only connecting on 20 channels, and the remaining channels have a null signal level. The status light on my SB8200 which lights green for DOCSIS 3.0 or blue for DOCSIS 3.1 is lit green. Despite all this, when I call Cox support, their "system check" says my modem is working "perfectly" and supposedly "will not let" them create the service call for the tech to come remove the filter. This should be trivial to address but I can't get it addressed. Has anyone gotten a similar issue resolved? Is there a moderator here who could reach in and get this call scheduled for me?Is Docsis 3.1 more susceptible to upstream noise than Docsis 3.0?
I've been a Cox customer for 22+ years. I've rarely had any issues. A few years back, I had had voltage on my upstream and they replaced a cable from my house to the pole. But other than that, no issues at all. I had a 16x4 Docsis 3.0 Netgear modem. Was on the 300/30 plan. It was pretty fast, like I said, no issues. So last week I got the email blast about upgrading to Docsis 3.1, figured I would go ahead and pull the trigger. It worked blindingly fast for the first day or so, was getting around 850 down and 34 up consistently, no issues. Then it started dropping to nothing. Every day since then, still getting about 750-850 down, but only getting 0-10 up. It says I have between 40-60% packet loss. Constant disconnects. Cox is telling me there is "noise" on the upstream line. So what changed between me having Docsis 3.0 and switching to Docsis 3.1? I have a Motorola 8600 modem. Is Docsis 3.1 more susceptible to noise?
My docsis 3.0 router supports 340mbps, rented routers are a scam.
I placed an upgrade order for the internet ultimate, I noticed it has been processing for about 8 days, so I talked to a chat rep who told me my router isn't compatible with my upgrade to the internet ultimate, she claimed that my modem router only supports up to 150mbps wireless due to it being docsis 3.0 and I'll have to rent a new one through Cox. I explained to her that my modem router actually supports up to 340mbps wireless and 1gbps wired, and that I mainly use the wired service, I even offered to link her the specifications listed by the manufacturer to prove this to her, she ignored this and told me they cannot do it. I asked for a supervisor, sheasked me to wait then disconnected on me. I'm not paying for a modem router that will not benefit me in anyway when I know my modem router is more than enough.
