ATT download around 900 mbs but upload speed is less than 10 mbs on ethernet connection

So as stated above my download speed around 900 mbs and less than 10 upload connected through an ethernet cable. When i'm connected through the wifi i get speed for upload and download both around 400 mbs per second which i am okay with. But i don't understand what could cause my upload to be so low with an ethernet connection. I only have this one computer to check the ethernet with speed tests, i did speedtest and the one provided by att both giving me the same 900 download but less than 10 upload. i tried calling customer service but they couldn't help me and just gave me the usual turn the router off and on and try again and after that didn't work i was told to try again in 15 minutes and they ended the call as if the issue had resolved.

yes it is the "Killer E2400 Gigabit Ethernet Controller #2"

     Hmmmm......you might Google killer network slow upload and look at some of the pages covering an issue with their control center and Win10 v1803+.  It sounds exactly like what you're experiencing and there are some fixes that seem to eliminate the problem.

Hi @lyuliyl,

 

We will be happy to help!

With a 1000 mbps package you should definitely be getting much faster upload speeds and consistently faster download speeds to your devices. When you run these speed tests on devices, are you making sure that the devices aren't running a lot of background applications, and that there aren't multiple devices running an internet program at the same time? Also, have these speeds always been this way, or did this just happen recently?

We also recommend trying our Troubleshoot & Resolve tool for diagnostics and personalized solutions to any issues found.

Let us know if this information helps, so we know how to proceed.

When i run these speed tests the only thing that is open is chrome which is because it is running the speed test. This has never happened before but keep in mind it was because i had never tried it before. I've always had my computer connected through the wifi and not actually hardwired to the router. so with the wifi i get the speed around 400-600 for both download and upload but when it is hardwired i get a really good download of 900 but a horrible upload of less than 10. I ran it again and the upload got down to even .8. I have reset the modem pressing the red button in the back for 10 seconds and i know that did reset it because it turned off and also deleted a dedicated port that i had opened for a minecraft server that i have

Hello There @lyuliyl,

 

Thank you for trying the troubleshooting steps that are included with the Troubleshoot and Resolve Tool.

 

Here is some more help about Optimizing your Networking Experience, that may be the ticket to get your upload speeds back up to par. 

 

Try those things. In your next reply, if there is one, please send us a screenshot of the most recent speedtest results from speedtest.att.com.

 

Thank you for being and AT&T Customer,

Given your testing with wifi shows what is normally about the max speed for wifi connections, it seems clear to me that your computer is capabile.  That means the issue has to be with the Ethernet chip in your computer.  Have you tried a different Ethernet cable?  If that doesn't make a difference, understand that some Ethernet chips (like Realtek) just don't like the AT&T equipment for some reason.  A long shot but I'd say try disabling IPv6 in the properties for the Ethernet connection on your computer and see if that helps.

So i did some more testing on the computer, just in case it helps i have a "Dell - G7 15.6" Gaming Laptop - Intel Core i7- 16GB Memory - NVIDIA GeForce GTX 1060 - 128GB Solid State Drive + 1TB Hard Drive" i took the title from best buy. I tried running the test with both the ethernet cable that i bought and the one the comes when they give you your modem and such. When my laptop is unplugged from the power it gives me speed of download pretty low even with the ethernet cable (around 200 or so download) and the upload remains the same (below 10) and when plugged in it gives me speeds of download around 900 but the download still remains the same (below 10) I also just tried disabling ipv6 from my computer settings but it didn't change anything. So from this i can conclude that it is not something to do with the ethernet cable that i have and more than likely is either one of the settings on my computer or one of the settings from the modem.

I also just tried disabling ipv6 from my computer settings but it didn't change anything.

      Did you change it in the properties for the Ethernet connection or the WiFi connection? 

 

     Also, it looks like it could come with either an Ethernet controller from Realtek or Killer Networking.  Can you tell which one it is?

 

     The difference in speed between battery and AC power is understandable as the power profiles that Dell implements turn down the network (and other) settings to conserve battery.

You are a literal god, your advice was spot on. I looked it up and followed the instructions to uninstall it and install it again and now both my download and upload are over 900. Thank you so much for your help

Is there a good technical service part of AT&T Small Business that can help me get close to the Fiber 500MB of download speed I have been signed up for?  I have tried several times to get help but no luck from the technical support team.  In fact, there is a Trouble ticket I submitted back in August and followed up on in October, but no luck.  I don't want to post all problem here, but want to give AT&T a chance to make the service they promissed right.  So, in sum, based on all of the speed tests I have run over the past year, I am getting less than 50% of 500 MB of actual download speed.  Any suggestions on what can be helpful (fastest modem allowed by AT&T, fastest router that works)?  Frustrated with no real choice of internet providers.  Robert
