WIFI Upload speed slow (throttled down)

WIFI upload speed is so slow on windows 10, 0.4 MB, compared to 3 MB when running on the same device from linux. The issue happens on 2 different devices, which rules out a device issue, and is running perfect from linux, which rules out a network or device
issue. Speed is fine when using a wired connection, and download speed is always good in all cases, 38 MB. Upload speed is fine when running tests from my android phone as well.

So the only situation where the upload speed throttles to 0.4 MB is when using WIFI on windows 10.

Solutions i've tried include DisableTaskOffload & "netsh int tcp set global autotuninglevel=disable", booting in safe mode, uninstalling-reinstalling drivers, resetting internet connection, updating windows, searching for drivers update in device manager,
and more.

Seems to be a windows 10 issue, trying to throttle down upload for some reason since it is happening on two different devices with different configurations, and as it is working fine on linux on the same devices.

Appreciate any feedback or proposed solutions.

 

Slow upload speed over WiFi

I have just had my internet upgraded to full fibre and get 500Mbps upload & download.
I have multiple devices on the WiFi network and they all get at least 200Mbps upload and download, all except my desktop PC which gets 500Mbps Download but only 4Mbps Upload.

I have used my Android phone and laptop at the exact same location as my desktop and get over 350Mbps upload and download.

I have been using SPEEDTEST by Ookla to check the speeds.

I need help to figure out why my Desktop PC is so slow.

It has a Aorus Gigabyte GC-WBAX210 wifi card installed with the latest Intel drivers.

Any suggestions on what i can try would be much appreciated

Slow downloading speed

Hi,

Are you on a laptop or a desktop?

Is the computer plugged in to charger when downloading? (laptop)

The download speed has as much to do with the website server where you are downloading a file from as it does with your internet connection speed.



You can have a very fast internet connection, but experience very slow download speeds if the website has a slow server. This could be caused by very heavy traffic on that server or it may just be a slow server.



One thing you can do to check is to go to the following website and check your speed.

Speedtest.net:

Speedtest by Ookla - The Global Broadband Speed Test

Try several different test websites there to see the different download/upload speeds.

Compare the results with the website where you are seeing the slow downloads.
