Atheros QCA9377 - Slow wireless speed

I've tried a lot of distros, but internet speed barely reaches 500kb while it reaches 30 mbps on windows on the dual boot.
As of now I've tried Power management settings.

Dell i5 3567
Qualcomm athenos wireless wifi network chip.

Hi there, welcome!
Please provide your system specs via inxi -Fza as text, formatted with 3 ~ before and after the text block.

We neither have any influence on the download speed nor do we install brakes.
If the servers are in high demand, as is the case with Arch or Garuda, traffic jams can occur :wink:

Several common Atheros cards have a multitude of different fixes.

Without knowing your specs we really can only make general recommendations.

As your wifi driver module(s) are included in the kernel the first place to start is with testing alternate kernels. Have a look at other posts on the forum in the Networking category to see which kernels are most often reccomended for troubleshooting purposes.

Run inxi -Faz in the terminal. Find your Atheros wifi chip model and search the forum for fixes for your specific model. Post all fixes you have attempted and the results.

Be sure to post the output of inxi -Faz.

Welcome to Garuda.

These is my setup

Many fixes you could test on this thread:

Kernel boot parameters are likely your best bet.

Try these options individually or in combination.:

ath10k_core.skip_otp=y

or

ath10k_core.nohwcrypt=1

or

pcie_aspm=off

I would also disable IPv6 and test alternate kernels.

Welcome to Garuda, I hope you don't mind I edited your thread title to include your adapter model.
