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?1.2KViews0likes3CommentsSevere 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.1.2KViews0likes5CommentsZip 85209 Mesa AZ--Noise On Backbone
I have hesitated to air this issue here but I believe the seriousness of the issue warrants an explanation of the problem I've been fighting for almost two years. Keep in mind I am located in Mesa, Arizona Zip 85209 and your issue may be totally unrelated unless you live here as well. The issue cropped up around two years ago At that time I was on the 50/5 plan. I noticed slower than normal speeds particularly on the up-link side. I went through the exhaustive Cox phone help with eventual replacement of the modem on two separate occasions. Neither replacement helped my problem. During my many conversations with the phone troubleshooting folks they often commented to me they couldn't "see" my modem and therefore couldn't perform the reset remotely. I found that troubling as that pointed to an issue outside my house. After repeated technical visits to my house where every single connector, coaxial line, and jumper was replaced at least twice the staff then concentrated on the pedestal in the front yard. Some sort of noise was being generated into the pedestal. After confirmation of the noise a Cox network tech (not a sub-contracted company) disconnected the culprit four blocks away from me. Amazingly my service worked normal for the next 24 hours. Unfortunately the problem returned. At this point let me say repeated trouble tickets will eventually get you to a higher level place in line. Even though it is frustrating as a customer to continually report the same problem believe me it eventually gets someones attention. I was contacted three weeks ago from a senior Cox network supervisor who confirmed indeed my problem was noise and it was on their side of the house. Specifically it was noise being generated and as it traveled the up-link side of their network it was being amplified and thrust onto the "backbone" of their network. Needless to say folks this is serious stuff for Cox. I am not the only customer being affected as you can well imagine. I was contacted yesterday, 10/21, by my contact who is just as frustrated as I am. The noise builds but while troubleshooting its state is changed and the noise disappears. When it does the backbone returns to normal activity but the noise will start to build again eventually taking over the up-link (egress) side of their network. I spent my life in communications and therefore know the plight the Cox techs are having here in Mesa, AZ. That's the reason I am sticking with Cox as my background wants to see this through with them and to share both their headaches and eventually joy when they find it. Believe me I have thought about going to Centurylink, their competitor but I refuse to bail now since they are finally on a trail. So, if you live in Mesa, AZ and have experienced the same basic things I have spoken about it may very well be the same noise issue I've had for a very long time.1.1KViews0likes1CommentIncreasing frequency T3 intermittent timeouts
I've been having t3 interference and subsequent intermittent disconnects for about a year now, have had techs out multiple times only to tell me they dont know the reason its happening. Linked is pics of what I think is the issue -- upstream bonded noise, I have changed modems 3 times (all self-produced), currently these stats are with Netgear CG3000Dv2 , its happening more and more often, I'm about to cancel service if I can't solve the problem. =( (I dc'd twice while writing this.)2.2KViews0likes4CommentsMy box makes a crazy noise and sound doesn't match picture.
My box makes a crazy noise before playing something from OD or changing the channel and the dvr list. any HD channel I go to the sound is lagging behind the picture and after 20 minutes or so on regular channels it does the same thing. i've only had the box for two weeks its been doing this since the beginning.2KViews0likes1Comment
