Fedora 25 WiFi speed - Upload capped/Download OK

First of all, I'm not an expert in Linux, far from being one, but I am normally handy enough to fix almost anything on my linuxes installations (thanks to google and the community of course).

I'm a regular Windows user which, from time to time, likes to have a 2nd Fedora installation and even use them as a primary one for extended periods. Because of work tools and games, normally I tend to get back to Windows.

Having said that, this problem is bogging me since the past weekend and for the first time in my life, I'm reaching for help since this should be something pretty easy to fix and I'm missing it somehow.

HW Description: Fresh Fedora 25 installation on my laptop. MSI GS60 Ghost Pro 4k - Wireless device:

@fedora ~]$ lspci | grep -i wireless 05:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 20)

From beta.speedtest.net , I was comparing WiFi throughput from Windows to Fedora, I was very surprised by the results (worth saying I have 1gbps fiber so normally I maxed out wireless).

Windows: ~330mbps down / ~330mbps up Fedora: ~400mbps down / 25mbps up

1st) Downloads from Fedora are much faster. 2nd) Uploads are considerably slower. So slow, and consistently slow between at around ~25mps that made me thing that it might be something that is limiting the throughput.

What did I check?

  • It is indeed connected to 5ghz.
  • It is indeed downloading as fast as I ever seen on my laptop.
  • I tried this a couple of meter away from the router withing the same room. So signal was perfect.
  • EVERY data sent from WiFi was capped at ~same speed. Tried samba and SSH transfer as well.
  • Cable was the expected ISP maximum ( ~900mbps/~850mbps), same as Windows.
  • Fedora is fully up to date, and checked the wireless driver and seems that I have the latest and greatest (?) :)

I'm willing to spend time troubleshooting, testing and answering questions if needed.

Is there anywhere that I can set traffic caps for my wireless interface? Something that might have been there from the get-go? I would suppose not but....

Any helps is appreciated.

Thanks!

I can confirm, I am also having extremely slow speeds on Wi-FI. Tested on Windows laptop and getting maximum capacity.

I've just re-done the test from Windows and immediately booted back to fedora:

I'm currently sitting 10 feets from the router in the same room on both tests. Today I had higher uploads in fedora. but look at the windows ones.....
