Slow upload speed
Hi,
Dell XPS 13 (9380)
Windows 10 Pro, v.2004, osbuild 19041.746
Core i7 16GB 1024GB SSD 13.3"
(source, in swedish)
I have very good download speeds (250 mbps) but bad upload speeds (5 mbps), it should be around 250 mbps both ways.
It does not matter whether I'm on wifi or ethernet cable.
When using my phone (Iphone X) on the same Wifi I get 250/250mbps both ways.
So the problem is neither on the ISP side, nor on the wifi side. It is something else.
Any ideas on how to troubleshoot this? I've no idea where to start..
Thanks!
Einar

No ideas?
My wifi-adapter is a Killer 1435-S.I can't find another network adapter expect one that is tied to WSL. And the problem persists whether I connect through ethernet cable or wifi.
I've been searching for a way to check if "full duplex" is turned on but can't even find it in the settings in the device manager.
I have the latest drivers (12.0.0.948).
What can cause this?
