The same issue is still occurring. I now have months of data collected to support packet loss beyond my home, as well as an in-home Cox technician that confirmed the infrastructure beyond my home was the issue and that he was seeing packet loss at my tap while excluding my entire internal network. The call date was September 8, 2018 and packet loss beyond my home should be notated on my account in accordance with that call.
Here are screenshots from a packet testing utility I've been using while hard wired to my modem and through a router - the same packet loss issues persisted with or without the router in between. Packet loss also persisted through different hardware and operating systems. This packet loss issue persisted through three separate/new routers, two separate, brand new DOCSIS 3.0 modems, a Cox supplied Panoramic modem/router combo as well as the current Motorola MB8600 DOCSIS 3.1 modem. The modem provisioning can be found in my account history.[img]https://i.imgur.com/gPOGI2V.png[/img][img]https://i.imgur.com/BIlwdLw.png[/img]
In the photo below, you can see lost packets using UDP (in the Ping Plotter application window, not a normal ICMP request that would normally be dropped due to low priority) and a normal ping in the command prompt window both displaying dropped packets at the same time using two separate types of communication:
Here is a screenshot from my modem indicating the uptime (less than three weeks, modem is brand new) and the several hundred thousand of corrections needed on bands 2-21:
I called Motorola to confirm my understanding of the "correction" column, and was immediately informed that the number of corrections based on the modem's status page is indicative of an issue with Cox's infrastructure beyond my home.
My RG6 line runs direct from the tap at the outside of my home to my modem - no splitters or other devices in use, and was replaced about two months ago by a Cox technician. The RG11 line that runs from the closest Cox ingress point to the outside of my home was replaced as well, about two months ago.
There is a problem with the Cox infrastructure in my area of Phoenix. I've been dealing with this problem for months, and have provided Cox with dozens of data sets like the ones linked in this post - yet no tangible corrective measures beyond replacing the lines running to my home have been taken.
I currently have a complaint in with the FCC and FTC, and will continue documenting and communicating this information out until the issue of packet loss is identified and corrected.
I hope they fix this for you! I'm in Las Vegas and just had my first packet loss issue tonight. Download is fine, Upload speeds are at crawl speed and I can't play Fortnite or stream on Twitch since 6 PM, just about 8 hours now.
Tech support told me my modem was bad, no other complaints in the neighborhood. So I went to Walmart and got a brand new one... $97 later... still 25% packet loss in Fortnite and 50% loss in StreamLabs. Tried disconnecting the router, no go. Service was 100% perfect for months now... I think I took it for granted. This is horrible!
They have an appointment setup for tomorrow and no way to escalate the issue because nobody else is reporting it. The packet loss is only on the upload, so probably nobody even notices it.
Anyway, sorry to hijack your thread a bit, but I needed to vent a little. Hope they get it fixed for you and also hopefully my problem goes away so I don't need to make a thread of my own for Vegas! Peace <3
Well, at 5:15 AM, my internet went down entirely. All the lights on modem were off and it reset. Came back up and no packet loss with 90 mbps down and 12 up. Tech support did try to reset the modem 6 hours ago and it didn't help. But someone did something this morning to fix it. Thanks! Good luck on your Phoenix issue!
Try Ping Plotter - it's the program I used to narrow down the issues of packet loss and high latency during outages. You're reporting the exact same symptoms I had - which turned out to be bad Cox infrastructure/equipment in my area. Don't make the same mistake I did - get data right away, and have techs come out during peak times when the packet loss is likely to occur. If you see a trend (which I did this week), see if they can come out and test when packet loss is most likely to happen - and request an actual Cox employee. I'm not sure about Vegas, but the non-Cox/outsourced techs they use in the Phoenix area are very very very bad. In the course of troubleshooting this, I was told by an outsourced Cox in home tech that my problems were due to "having too many things plugged in". It took thirteen on site tech visits before Cox finally confirmed the packet loss issue while excluding my internal network. Thirteen. Most of which were outsourced technicians who wanted to get in and out as quickly as possible, to theoretically maximize the number of visits and subsequent payments they receive. I'm fairly sure you are if you're streaming - but testing while hard wired to your modem/router is the way to go. To vet my network I tested while hooked up directly to my modem and had data showing the issues persisted with that setup as well. Another thing to try would be to manually assign DNS servers. This didn't help me, but if Cox's DNS servers are problematic, it might help. Try 220.127.116.11 and 18.104.22.168 or 22.214.171.124 and 126.96.36.199. Both are low latency/reputable DNS servers.
If all else fails and you have data to show that Cox's infrastructure is the problem, file a complaint with the FCC. The more records the FCC has, the more data about Cox's aging and unreliable infrastructure will be in the public records. https://consumercomplaints.fcc.gov/hc/en-us/articles/115002206106
