Atheros QCA9377 WiFi - Slow Download speeds

I installed Garuda dragonised edition recently but download speeds are very slow . like less than 10 KB/s sometimes . Update fails due sometimes says less than 1 byte downloaded in last seconds .
But when i open a browser and start browsing continuously (while the thing is downloading in background ) like starting new yt videos etc. then download speeds in terminal or download manager become normal , touches upto 6-7 MB/s
Is this a known issue ? any fixes ?
Note - 1) It was not happening on first boot , dont know when it actually started happening .
2) I am using a downgraded kernel .
3) File downloads through browser are also slow .

Did you use garuda-update?
Did you use for best mirrors with

This is the first thing I’d try to fix.
Not necessarily the root cause of this issue (but definitely possible), but it’s risky and discouraged to stay in a partial upgrade status.
I’d rather start testing a few other kernels, starting from the linux-lts.
Also a reboot is pending (just in case, and to clear up the garuda-inxi, which still does not show the partial upgrade after the last update)


Well known to be a problematic adapter.



I was talking about general download speeds and not downloads from repo specifically.

Thanks for highlighting this .

And the weird part is shows 50 mbps .
But downloading files is very slow . Sometimes when i continously browse like load yt videos . Download speeds increases. Like it remains in bytes sometimes but if i browse it touches several mb's

Have you tried adding the kernel parameters that were suggested in the link I posted?


Reboot (power cycle) your router.

Make sure your router firmware is up to date.

Test different kernels.

Test the linux-firmware-git package.

Test different DNS servers.

Disable IPv6.

Be sure your BIOS is up to date.

Please report on all fixes attempted.
