Hi, i just installed fedora onto my laptop and my wifi connection is about 1/10 what it should be. i didnt have this problem with windows or linux mint on the same machine nor do i have the problem when using an ethernet cable. just wifi on fedora.

here are my specs
System:
Kernel: 6.8.6-200.fc39.x86_64 arch: x86_64 bits: 64 compiler: gcc
v: 2.40-14.fc39

i have tried

  1. turning ipv6 off
  2. removing ath10k firmware 6
  3. connecting to other wifi networks
  4. turning battery saver mode off
  5. updating bios to the latest version

if anyone could help me that would be great. thank you.

I have the same card as you do and probably the same problems. I tried out some things with Void Linux, I don’t know how they work because I didn’t get too deep on it, but it could give someone a clue.

I tested different network managing services. When I used NetworkManager, IWD, and ConnMan, every single one of them only gave me 30 Mbps of download speed. wpa_supplicant with dhcpcd gives me 188 Mbps, which is limited by the distance from the router.

Try upgrading to Fedora 40 and check if the issue persists.

How and what specifically? It sounds like possibly disabling wifi power management or BT coex may help.
