Windows 10 1903 - Slow download speed

[Varusal]

Hey folks,

I currently encountered a weird issue with windows and my network speed. So the weird part is that under Ubuntu I get my speed.

Tried Safe Mode / reinstalled the network chip driver. Still no changes. Does someone has encountered the same issue?

i had problems when i used to install my drivers for a network card, if i didnt install them and kept it on windows default speeds were fine, so maybe u try too , uninstall driver and let windows default do its thing

What exactly do you mean? I can use what ever speedtest server I want the results are the same.

I had this problem on my laptop from the day I bought it but strangely it suddenly disappeared.  Nothing I did seemed to make a difference at the time, I couldn't spot a specific update that fixed it, I just booted one day and it was fine.

The strangest thing is if I use a VM on my Windows OS and use bridge-mode, the VM gets the full capacity.

But if I use my actual windows client with the same NIC I only get ~170.

When trying to fix mine I followed one suggestion to disable QoS on the specific network adapter under Change Adapter options, Properties, untick QoS Packet Sheduler.  That didn't seem to do much at the time, but checking now it does seem to make the speed more consistent.

That didn't changed anything, sadly.

Yeah I think it only impacts now because the main problem was fixed, somehow.

Mine wasn't caused by 1903 though, it was from the fresh OEM install which was 18xx something or other.  Wasn't fixed on 1903 either, was something much later than randomly fixed it.

It could be a different issue as I used iperf3 to test to my NAS to confirm the issue was not Internet related.

Are you definitely fully Windows updated?

Yep I am. I reinstalled the latest big update but that didn't changed anything. Guess I have to wait till the next big update because I won't reinstall windows again.

I'd pretty much resigned to booting to Linux to copy any large files, when it suddenly started working.  Absolutely bizarre.

 

Although in my case I'm not sure it was slowing down the Internet, it was just halving my network performance in general.  But then at best my broadband can hit 120Mbit, so there might be some sort of threshold where it kicks in that my broadband wasn't fast enough to hit and yours is.

I fixed it.

I needed to set the following setting: netsh int tcp set global autotuninglevel=normal

Everyone said that I should disable that setting. That is what broke it. Now it's fixed

Interesting, because I did also turn that off, didn't fix it, turned it back on.  Now I'm wondering if I gave up at that point, not knowing I had actually fixed it.

Did you check what the setting was when you started?

Yes, it was disabled. But I didn't disabled it, so it must be caused by an windows update.

Mine certainly wasn't, or at least it THOUGHT it wasn't, you never know with Windows.
