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?
Severe Packet Loss - Noise issues
For the last several months, we've had techs come out to the property to address packet loss. We've moved the modem, replaced our router and modem several times, and replaced some connections outside the home. The issue is still there, and I am unable to play games like Counterstrike without rubber-banding crazily. The last time a tech came out, he stated that it's "unlikely" maintenance will come out to address the issue, because it seems "fine" on their end. It's clearly not fine. He mentioned that we are at the very end of our neighborhood, and it's possible that there's noise, causing issues with bandwidth. This is a consistent issue. When running a ping test, the time (ms) is consistently between 14ms-50ms, but shoots up as high as 492ms. I've tested a wired connection on both my PC and laptop, and the results have been the same. This has been incredibly frustrating, and the tech visits have been endless. What are we even paying for? Edit: Any advice would be helpful. The last thing the tech on the property said before he left was, "to keep calling us until it's fixed". My last resort is to switch providers.
