Within a day or two of this happening, I moved my modem and router to more permanent locations in my utility room which required me to unplug both from power and the ethernet cable between them. I do not believe this had any effect on the issue I was having. I did see teams of trucks working on some kind of buried cables in ditches near my house (1/4 mile away) but they had been gone for a week or two before the issue dissipated. They did not have obvious Cox logos on their trucks. I'm guessing my issue was node oversubscribed, and it was resolved by upgrading and splitting nodes near me, but Cox has not confirmed the issue or the resolution. As I described before, they were not willing to give me more information, add me to the "escalated ticket for my area," provide advanced troubleshooting or anything else beyond confirming my issue description matched an existing escalated ticket and "they hoped to have it fixed soon." Re: Ridiculous packet loss and latency. Not likely. (If they haven't already) First they'll tell you it has to be your equipment, and try to talk you into renting theirs ($10+ per month). Then they'll say they have to send a technician out, who will again tell you it's definitely your equipment (this costs $75) and they'll say they can waive those fees and support all your devices if you subscribe to tech support for $20 per month. If you're lucky, after you pay some or all of these fees and replace your equipment a couple times, they'll "find an issue in your area" and run wires to your house again, and when that doesn't fix it (because their node is oversubscribed or allowing too much noise) they'll "escalate a ticket" and tell you "it'll be fixed soon" - kind of an empty promise, because you've already wasted a lot of time and money on it and "soon" doesn't mean the same thing to them that it means to you and me. Can you tell I'm bitter having been on this carousel for a while already? Re: Intermittent disconnects with new service, slow speeds overall - SB8200 in Omaha area Update: Cox contacted me after I reached out on cox.help@cox.com as suggested. After reviewing my logs and account information, they determined there is a known escalated issue in my area that they hope to have resolved "soon." I asked if reducing my Internet package to one that uses Docsis 3.0 to avoid noisy channels would help and I was told "no." I have continued to troubleshoot router connectivity to verify the issue is not on my end, and it is not. Still no resolution; the frequent disconnects, DRW window violations and uncorrectables on one channel are still causing 10+ disconnects per day, some 1-2 minutes but one today (in the middle of an important Zoom call for work) was just over 10 minutes long. Re: Months of poor internet performance; what will it take to get an actual repair? I'm having exactly this same issue, and all I was told was "We're aware of an issue in your area and we hope to have it fixed in the coming weeks." No timeline, no description, no service discount since I can barely use the service... I was also told it has nothing to do with having 500Mbps (requires 32 channels) and wouldn't go away if I dropped to a lower package and used a Docsis 3.0 modem. But I can't really believe anything they say, it seems to all be coordinated to convince me to purchase a "technical support" subscription on top of the terrible service agreement I have. Re: Dynamic Range Window violation, RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW, and T3 timeout Having this exact same issue for the past 6 weeks. Social media team "researched my case" and eventually said there is a "known issue in my area that they hope to resolve soon." No resolution yet, still getting disconnected 12+ times per day. Re: Dynamic range window violation I'm having this same issue also, almost exactly. I posted about it in these forums and they said they'd need to do some research on my exact situation, and eventually got back to me saying "there's a known escalated issue for your area that we hope to resolve in the coming weeks" and no further information on it; they can't attach my name to the ticket, they can't discount my service because it's barely useable, they can't give me updates as they occur, and of course they have no timeline for resolution. At least I haven't had to replace hardware and lines and pay for several technicians to come out. This is f*****g ridiculous. Intermittent disconnects with new service, slow speeds overall - SB8200 in Omaha area I started service 2 weeks ago when we moved into my new house in an Omaha suburb. Previous owner had Cox (looked like a business modem, but was ~12 years old). I'm paying for 500Mb package but we rarely get that. I activated service over the phone and installed my own Arris SB8200 (bought just for Docsis 3.1 for this new package, my old modem was Docsis 3.0) directly on the main line, after removing all the splitters inside because I don't use cable TV. It activated fine, the tech I spoke to on the phone didn't see issues and a quick speed test showed speeds close enough to 500, so I connected a router I bought a year ago (Netgear Nighthawk AC2300) and updated the SSID/password and started connecting my devices to wifi. Over the next few days, we had intermittent disconnects but didn't notice them much because we were moving furniture and setting things up in the new house. When I started working from home with my laptop, I noticed severe disconnects during Zoom calls but streaming video on TV was fine (later found out it was buffering far enough ahead to continue through the outage, most of them last 3 minutes or less). Fast forward to this week, we're getting ~8 disconnects per day ranging from 2-7 minutes long, some as often as 15 minutes apart. I see 32 channels on my modem status page, plus channel 159. Channel 159 has millions of correctable errors (which I understand is not a problem) but Channel 22 has hundreds of thousands of uncorrectables per day. I'm also seeing DRW errors in my modem's log and sometimes sync errors, some of them coincide with the outages but sometimes do not. Speed tests via the router firmware have also dropped a great deal, yesterday as I investigated, speedtest.net showed download speed of 150Mbps, far lower than the 400+ I was seeing at activation time. Ping and jitter consistently test much lower than my previous service in another city, but the inconsistency caused by these disconnections has made the overall performance much worse. I have called Cox about this twice and text-messaged Support, but they throw their hands up and say it has to be my equipment because "everythinghas green checkmarksexcept OFBM status" and when I ask to be escalated to someone who can look at my logs or status with me, they try to sell me Complete Care or convince me to pay to send a tech out (who will likely throw hands in the air too and want me to pay for something that's not my fault). What else can I do? Is there a secret to getting help and resolution from Cox? I mayhave just gotten bad level 1 agents but I'm not getting the service I'm paying for.
