Atheros QCA9377 WiFi - Slow Download speeds

Issues & Assistance Networking Support
1

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

sudo reflector --country Germany,France --latest 5 --age 2 --fastest 5 --protocol https --sort rate --save /etc/pacman.d/mirrorlist && bat /etc/pacman.d/mirrorlist

?

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 speedtest.net 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?

Also:

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.
