Download speed fine. Poor/intermittent upload speed.

Definitely have been seeing suppressed upload speeds for the past year just really gotten so bad, can't even upload emails and simple sights sometimes lately. I have the basic internet 10mbs download and 1mbs upload. Used the Chat to talk to Cox and they wanted to charge me to send someone out when i know it is their problem. I have never had any issues with my equipment and even have duplicate backup modem and router etc that show the same slow upload speeds. Download speed is fine and never had any issues with upload speeds before until the past year after i switched back to the basic internet since i can do everything i want with the basic service. Cox always wants to upgrade me saying that will fix my issues but that is just not true. I am not some new person to the internet have over 30 years experience. The customer service on the chat was a real *** to me and Cox does not care about its customers that is for sure. You can literally get 3 to 10 times the speeds at half the price in many other countries which says alot about the U.S and its price gouging. But to not even get the service speeds that you are paying for is just plain extortion.

up to 10, not guaranteed.

Apparently Cox deployed some underhanded rogue tactics and switched Preferred 150/10 into Preferred 150/5. I received zero notice about this and feel scammed. What can anyone do with 5 up? This is a joke. Verizon please come to my town.

I have been having an upload speed issue as well for several days, maybe weeks. I'm in the Orange County, CA region. I already made my own thread before I noticed this one, but I have been getting anywhere from 1-10 Mbps upload speeds lately, used to have no problem hitting 30 (Ultimate tier).

Been having this problem since last month. Can't Twitch stream from around 5pm to even as late as 11pm my upload speeds take a huge dive from 35-38mpbs to 1.50-12mpbs and it jumps all over the place. I had a technician come out two nights ago and said all the readings were fine and was told that since it's a shared line it has it's slowdowns around that time of day. This happens almost nightly.

It's difficult to stream earlier as I get home from work around the same time. It's unacceptable to be paying so much money for Gigablast internet where I have to wait until morning/afternoon to have acceptable upload speeds. I've already swapped out my first modem (Cox's own Panoramic Wifi Modem) with a new one at a Cox Solutions store, I've swapped ethernet cables to CAT6 ones, I've resetted my modem so many times and still nothing. Is there anything left to do to get the speeds I pay for on a consistent nightly basis?

Speed Test

Having the same issues here in CT for about 1-2 months.

https://imgur.com/a/YxjCAWVThis is the best thing I have found to prove that something is wrong with something that Cox has to fix and it is not your equipment.

SO DSLreports has a tool that you can use to push a constant upstream to see if your internet can support that speed. I have 150 download and 10 upload plan. The image I have attached has task manager open on the left and the dslreports tool open on the right. Using the 6.2 Mbps I have a constant buffer issue and the speed can never hold up to what is being requested. Now if I lower the request to anything below 3.0 Mbps I have no issues and hold that constant upload speed. I have been running in loops with support and techs coming out tell me something is wrong with my devices, because the meter tool they use shows the speed tests as perfect. So what I think is happening is the devices they are using are set to run the speed test at somewhere below 1 Kbps and there for not even trying to push enough speed through to see if the cable can actually handle it. So what is the point in paying for a higher plan? Download on the other hand works just how it supposed to and gets the speed that should. I have a technician coming on Tuesday and have asked specifically that it is a Cox technician and not a 3rd party or contractor so that the issue is directly taken up with Cox. We'll see what happens. I hope this helps people who are stuck in that annoying loop of calling tech support and having tech come out and them tell you everything is fine and when your the one paying for the service and know it is not what it should be.

Here is the link to it.

Edit: This is all on Cox equipment. Brand new out the box modem that was installed when tech came out yesterday with the exact same problem.

Edit 2:

This is about 2 hours after my initial post.

I now have these results on the exact same cable, exact same device, and exact same modem.

I do not know what is going on.. there's no way one hour it looks like the first test and the next it looks like the second.

Speed test results compared to Task Manager:

After running speed tests on multiple different sites the results being shown do show lower than what task manager is showing. Cox's speed test to be specific does show extremely low values and could really be broken.

This still does not explain the huge 360 that it just pulled within the span of 2 hours though.

Edit 3: After about another hour everything has been silky smooth. If something changes I'll update.

Edit 4: No change in the connection after some more tests, but the screen shot below is from a new computer being on my network and speedtest.net reads the correct values for what Task Manager shows. Not really sure why though... same cable, same modem. Only difference is what is listed as the source where the connection is being ran from "ONENET".

I then waited about 5 minutes for the laptop to get recognized closed the browser and went back to run another speed test and this time it shows "COX" as the source and the results are now displayed at the low values. But Task Manager is showing the values as being what they are supposed to be.

I do not really know what this information means. If a Cox support person would like to take the information I have found and do something with it your more than welcome.

Edit 5: So had Cox come out today 11/26. I just so happen to get the same tech that came out the last time. Showed him my screen shots and what I had found through my testing and that there are some irregularities. Advised another tech would come out in 5 business days or so and check the tap to see if anything looks wrong there.
