Cox download speed test2/24/2024 ![]() The upload speed DID update to 35Mbps upload, from 10Mbps, after yet another modem power cycle. Not a huge deal.except when I tested the speeds again, my download speed was still ~30Mbps. While in that chat, I received a text and email that my service upgrade was confirmed, so I guess I now have 1Gig download and 35Mbps upload, even though I declined it. I got another chat agent online and began the process again. He reset my modem one more time to test and I got disconnected from the chat. I declined the upgrade package as I wanted to get my problem fixed first. He insisted my modem was bad, that I should buy a new one, and he would upgrade me to the latest internet package of 1Gig down, 35Mbps upload (for just a couple extra bucks a month). I could see no such packet loss doing my own tests. One agent said my modem was bad because he saw 30% packet loss to the modem from his side, but otherwise it showed healthy on his end. Same results, ~30Mbps download, 10Mbps upload, whether connected through my router or direct to the modem. Power cycles, remote resets, health check on their end, etc. I spoke with live support chat a few times, each time going through the same old rigamarole that I had already done. I logged into my Arris modem directly and the Power and SNR values were all within manufacturer spec, everything was OK and Online, it looked healthy. I also directly connected both a laptop, and a wired PC, to the Arris modem via ethernet (bypassing my router) and experienced the same slow ~30Mbps download speeds with both devices. Several Windows PC's, laptops, mobile devices, Linux server, IoT, etcīefore involving Cox support, I power cycled the modem and router half a dozen times with no changes in download speed. Arris SB8200 bridge mode (self purchased, not a rental) Before I left town I had no issues with download speeds, although the last test I have in my Speedtest log was from and it was 476Mbps down. Speeds were the same whether it was wifi or direct ethernet to my router. My service (at the moment) was 500Mbps down and 10Mbps up. Speedtest consistently showed ~30Mbps download and 10Mbps upload. I returned from a 1.5 week vacation yesterday to extremely slow download speeds. Slow speeds are consistently reproduceable. Max speed wasseen in a few tests, but not reproduceable. Cox technicians have no idea what the problem is as everything looks healthy. Extensive testing and swapping modems, routers, PC/laptops, does not point to any single failure point. TLDR: Download speeds suddenly and unexpectedly dropped significantly below what my service is rated for. I do have a Cox technician coming to my house tomorrow to check the physical/wiring/cabling side of things outside my house. I am experienced with networking, routers, modems, systems, and troubleshooting, but running out of ideas. ![]() I work from home and need my internet working fully to do my job. This is an incredibly frustrating problem that I've spent just about all day and yesterday evening troubleshooting, so it is very long (sorry). ![]() Just asking.Location is Scottsdale, AZ 85254 if it matters. I've always wondered why when users post their Cox internet speed times that I never see where and how far away the ISP that they are testing and getting poor results. Since I'm not a gamer, so I don't think I'm bothered by the lower Upload as long as my Download stays around 220-240Mbps.which it has for a reasonably long time. ![]() Note: I could not find a way to clipboard insert or the insert a file into this message.asking for a URL?Īnyway, My question is what happened to my local area Upload speed to drop, and why would going to New England produce a higher number for Upload. Using PingPlotter, I get the following when I go to Cox.com(45.60.49.167), I show hop 6 (4.7.26.45) has a 45% Packet loss where all the other 7 have 0%. I've run the test to various parts of the country and notice higher Uploads to far away places like Nova and New England than to my local OC area. I've noticed that over the past week my upload speed has dropped from 10.7+ to around 5.5 or lower. I'm told I have the Premier with 200MBps/10Mbps upload. I run the speedtest to my local OC county and other areas. I've reset the modem a few times by the power cord. ![]()
