Cox install contractors
I've had cox Internet before about 4 years ago, recently had it reinstalled. The coax line from the outisde box ran to front of the house the the coax jack going into the house to hookup into the modem. Since then I've changed where my computer is located and where I put the modem. Now I want the coax jack to run to the back of my house to a back room. Do that I don't have to run coax through the attic. I have a brick home. The original instal had no masonry drill bit to go through brick. Rescheduled another contractor and had a note put on the ticket that I have a brick home. That contractor didn't bring a masonry bit. He goes to buy one then tells me two hardware stores didn't have them. Third contractor showed up. Not only did they NOT have a masonry bit. But they didn't have drill. Who goes to a job without a drill when your job will most likely have you using a drill. Cox has a serious problem with their contractors.
Internet outages wreaks havoc on VPN connections
This is a follow-up post as it seems my original post is locked for updates. I often loose my connection which only lasts for several minutes up to an hour or so. I am working from home using VPN and a couple minute outage will result in the VPN terminating. I opened a ticket with COX and they replaced my coax running from the house to the the tap outside and stated they also replaced a component in the tap. However, I still experience outages. I am posting my modem logs in hopes that someone can review and provide a recommendation as to the root of the problem? Thanks Status The statuses listed show the connection state of the cable modem.

I have been experiencing packet losses since February. I have been ping testing with CMD every single day and have noticed that these packet losses I have been getting are completely random. It can last about 1-5 mins to 1-6 hours. I have already contacted COX a few times already and they don't see anything when pinging the modem/router. I have checked the cables on my end, none of them are faulty. Resetting the box and router do nothing. They even gave me a new Modem/router just about a week or 2 ago and this problem still persists. Getting work done is getting to become impossible with these packet losses. I even sent an FCC complaint and haven't heard NOTHING back at all.
High-pitched sound from Cox Gateway
About a month ago, I switched to Cox as my internet service provider. The Cox technician installed a Technicolor CGM4140COM Panoramic Gateway here in the office next to my computer. From the start, the Gateway made a high-pitched humming or whirring sound when running. The sound was very distracting, and after a time when I was working here next to it, my right ear would feel discomfort or pressure. I called Cox to report the problem and was told I could go to the Solution Store and exchange the Gateway. I took it in and was given another CGM4140COM model. I hooked that one up, and it makes the same high-pitched sound as the original one. I now think the original one was not defective, but that all CGM4140COM Gateways make this sound. Have any of you experienced the same problem? If you have, do you have any tips or suggestions for how to remedy the problem? Thanks for your assistance.
New modem is still getting constant T3 and Dynamic Range Window violation errors
Equipment: OLD Netgear CM1200 (bought in 2020) Google Nest Wifi and Access Point (bought in 2021) TPLink 5 port switch NEW Arris SB8200 (purchased yesterday) Since the beginning of December 2022 my 2 year old NetGear CM1200 had been disconnecting daily between 6am-9am and every single day I had to physically reset the modem since the COX app and chat support couldn't reset it remotely. COX chat claimed it was my 27 devices connected to Wifi (I had the ultimate plan) and that I needed to upgrade to the Gigablast. Conveniently the Gigablast plan was on a deal that was $5 less than the Ultimate so I upgraded, same issue. I had a technician finally come out a couple days ago and he checked EVERYTHING. He checked the following with the following results Checked the connection to the CM1200, speeds on Gigablast was about 430mbps download and 27 upload. Disconnected the router and modem, connected directly to the Coax cable from the wall, speeds were then 830mbps download and 36 upload. Tested 10,000 packets and none were lost. Checked the network hub in the laundry room that came with the house (I don't use it since I don't have a switch in there), he saw there was a MoCA connection (I believe?) where the outside network Coax line was connected to the office coax line (which my modem was connected to) so he disconnected them and tested the connection to the outside network. The test results were 830mbps download and 36 upload.Tested 10,000 packets and none were lost. He went outside to check the network box on the side of my house and confirmed there is no splitter and that it's a direct connection, he tested the connection and the speeds were the same as inside.Tested 10,000 packets and none were lost. He went to the utilities box and tested the line there, he tested 10,000 packets and none were lost. Speeds were the same as in the house. All tests were normal. Ultimately he said that my modem was "likely" the problem and that I should try a new one to see if things improve. I purchased the Arris SB8200 yesterday, I chatted with Cox to activate it around 2pm and everything was good until 2am when my Google Nest Wifi notified me that the internet went out for 30 mins. I haven't had any outages since 2am so I checked the logs and it looks the same as the CM1200 logs were.
Does COX ROBO scan service with high usage and remove DNS / internet service?
Seems Like COX is Robo scan all stream usage and disconnect you from internet, we may be able to prove this, also why does internet disconnect and connect without having them to come as there is nothing wrong with connection. Also i would think they are scanning all not essential and entertainment urls and if that is the case they are disconnecting so it might be some sort of pack order for usage. please comment on my theory if any one else seems to think in same line, . I think to make good case, CPUC may need hard evidence to see what COX Communications doing. may be there is more to it.Constant Packet Loss For Years Now.
I have had cox's highest internet plan for as long as I can remember. I have had countless techs in my home including multiple maintenance escalation tickets called out for my issues. Still nothing changes. Every time I call to discuss the same issue, I get the same answers and have to fight to get escalated to a higher tier support so that someone understands what I am experiencing. I now chart all of my packet loss and am building a portfolio to seek legal action. I have the gigablast package which runs me $120.00 per month and can only use the internet efficiently approximately 35% of the time. As I am writing this post I have been incurring packet loss and disconnections for the past 3 hours. If a high tier cox tech would like to look into my account and see how many techs and issues I have had at my address, please do. I am going to keep posting all of my data graphs and information on the forums as calling and trying to get this settled is not working. All I can say is this has been an issue for years in my location and if I had the opportunity to switch providers, I would have left cox a long time ago. Please help! https://imgur.com/a/u0UVYJJ
85142 - The Internet is always hanging and then connecting again. I consistently see Uncorrectable Errors.
85142 - The Internet is always hanging and then connecting again. I consistently see Uncorrectable Errors on Channels 1,6,7,8, and 9 with Arris SB6183 16-channel modem. I confirmed outside connections are solid where we have an Antronix 4-way 5-1002Mhz splitter with four -7dB out connections. We also have a MoCA POE-F201C filter for the incoming line. No major issues until a recent Cox Outage and now constant issues. Any recommendations?7+ years of summer internet issues and packet loss in Sahuarita/85629.
Question(s): Is there a way to request an inspection / audit / health check of the neighborhood infrastructure? Does having IP addresses help narrow down potential locations? Is there a way to better seal or enclose equipment? I never had these issues over 10 years in the PHX area... and it is an objectively harsher environment for electronic survivability. I'm happy to help be part of the solution for myself and my neighbors… just let me know what I can do. However, having a tech come out to my house and start this debug dance for the 7th year in a row is just going to waste everyone's valuable time yet again. History: Entering year 7 of having summer internet issues. Always at or around monsoon season. Every year I am told that it must be my equipment. Every year a tech gets sent out at least once. Usually multiple times. Every year it takes 30-60 days of back and forth to resolve. It has always been cox equipment somewhere in the neighborhood. I work from home, and find this extremely frustrating. Every year I start all over again like bad internet groundhog day… explaining the history, potential issues, and following the same path of a tech at my door measuring MER and BER. It has never been my equipment… marginal improvement in performance gains. If I had any other reasonable option for internet service at my house, I'd have exercised it years ago. Issue: Here we are again… I was hopeful that maybe things would be different this year. However, there was broad outage in the 85629 area on 06/22/22 from around 0900-1200 AZ. After which, outbound packet loss has been intermittent accompanied by low upload speeds. This morning, my upload speeds have been abysmal. 1Mbps up to around 5Mbps. My normal upload speed is consistently ~35Mbps. Along with that, I am seeing significant packet loss. Outbound packet loss has been anywhere from 3-30%. Inbound speeds are moderately lower than normal, and I am not seeing significant inbound packet loss. Troubleshooting: 1. I've rebooted the router and modem multiple times. 2. I'm using hardwired devices, and have swapped between multiple ethernet cables. CAT5e and CAT6 on the off chance it would do anything. (I knew it wouldn't) 3. I've gone through 2 different routers, flashed the firmware of both routers, and gone direct through the modem. 4. I've used multiple computers to ensure the behavior is not limited to a single computer. 5. Still seeing the same results. Pathping: Shows no packet loss between computer and router, or router and modem. In fact, the first problematic node is 10.97.200.1 … I'm guessing the neighborhood switch, or other infrastructure. Followed immediately by 100.127.78.150, and 100.120.100.40. Ping Plotter confirms pathping's results. My neighbor across the street (who I share a tap with) sees the same frequent issues. One of my other neighbors a few blocks over is unaffected. 0% packet loss, and I believe they were unaffected by the outage on 06/22/22. Boosting my outbound power by adding attenuators has historically shown some level of improvement. 8-12dB has been the sweet spot, but isn't making a difference right now. Hypothesis: I'm going take a wild guess, and say that either the Wednesday worksite was not buttoned up properly after work finished, or another area has significant water ingress after recent monsoon rains. As the day has progressed (and the area potentially dries out), upload speeds and packet loss have improved. Twice now, the summer monsoons have flooded repair sites that were not properly sealed up. Occasionally, packrats get into equipment, and cause havoc.
Way too many service interruptions
This is the third service interruption since Friday. The number of service interruptios in April have gotten ridiculous. Why am I paying for a service I can't even use? It's absolutely unacceptable especially when this is the only service we can get in our area (74107). I work from the home via internet and that is now suffering because our internet service is unreliable. What is going on?
