Not Receiving DOCSIS 3.1
I would like to start by saying that I have tried with my utmost knowledge/ability to figure this out before coming to a discussion board. I got rid of the Cox Panoramic Gateway, and bought 3rd party equipment capable of DOCSIS 3. -Arris Surfboard SB8200 -AX1800 Router I have the 1Gig plan, and my hardware supports DOCSIS 3.1. To add to this, I cannot access my modem's settings to check signal levels or see if i could change those settings myself. Cox did not want to help when I called so any support would be appreciated.
DOCSIS 3.1 Upstream in New Orleans Area?
I have an Arris Surfboard 8200 modem and pay for Gigablast service in the New Orleans area. My modem shows a blue light for bonded downstream, but green light for upstream. Modem status shows 4 upstream bonded channels with power all 45.5 dBmV or greater. Is the upstream light staying green instead of blue because of a line issue, or is it because DOCSIS 3.1 upstream is not supported yet in my area?
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.
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?
Docsis 3.1 Upload Speed
Will Cox ever be able to take full advantage of Docsis 3.1 in terms of Upload speed? Will we ever have symmetrical? I'm seriously considering basing my home purchase on the availability of fiber internet (which is also abysmal in the Phoenix, AZ area between both providers) because I have serious doubts Cox will ever deliver. My internet bill (gigablast and unlimited data) is my 2nd highest monthly expense and I just don't feel I get my money's worth.
