Wired Upload Speed Issue

[Merilsion]

Currently my upload speeds are maxing out at around 0.4 mbps, while my download speed is at 900+ mbps. This is on a desktop I built a few months ago. My upload speeds were fine a few weeks ago, but lately have been terrible. I noticed the issue when I tried to go live on twitch. Initially I thought it was an issue with Twitch, but had the same issue on Youtube Live. I then thought it was an issue with my ISP but my upload speed on mobile is around 3mbps and a similar speed is seen other computers using wireless internet. I am not sure what the issue is, but my guess is the most recent windows update (but that's just a guess). My pc does not have an internet m.2 or other form of wireless card.

*Update*
I disabled Windows Auto-Tuning which has brought my upload speed up to 2.1mbps, but my download speed is down from 900mbps to 250mbps. Is this normal? This download speed is similar to that of my wireless devices. I may have resolved the issue, but I'm not sure download speed is lower now.

Disabling Window Auto-Tuning will hurt your download speed. This will not likely be the solution.

 

What is the expected upload speed of your internet? Are there any things that could cause latency between you and the router? (Switches, Wi-Fi extenders with an ethernet port, really long cables or multiple cables connected together, etc)

Not sure what my expected speed is. I have a relatively long cable from my router to my pc. But this has not been an issue till recently, so I don't know why it would be the cable.

Well generally if all devices are showing issues, its an issue with the gateway or its an issue with the service. If only one device is showing an issue than its the device. It sounds like other devices are having issues as AT&T Fiber is a symmetrical service last I heard. I know from reading that AT&T's gateway is a pile of shit. So that could very well be the issue.

 

Have you tried restarting the gateway?

The issue isn't on other devices, only on my wired PC.

That would indicate an issue if the upload speed on your mobile phone is only 3 Mbps. It should be around 1 Gbps like your download, while I know its wireless, Id expect at least a few hundred Mbps at the very least. I know for a fact you have Fiber. Because AT&T CANT offer Gigabit speeds via DSL, most VDSL connection top out at 50 Mbps, or if your close enough you can get 100 Mbps. Even with a crappy router, I would expect speeds higher than 3 Mbps on wireless devices. Even then lots of times rebooting can fix weird issues.

I'll try that when people aren't using the internet

Restarting the gateway did not resolve the issue. Download speed is high, upload is low.
