WIFI Atheros QCA6174 firmware issues, hangs

Hello there all,

I’m using Manjaro with

Linux w01 5.15.12-1-MANJARO #1 SMP PREEMPT Wed Dec 29 18:08:07 UTC 2021 x86_64 GNU/Linux

$ lspci

01:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)

This happens only when working on battery.

When this notebook uses the wifi, like updating pacman, its suddenly turn off the screen and shutdown.

Anyone knows how to get more information ?
Pls see journal below (Pastebin)

This could be done by TLP. To disable wifi powersave in TLP permanently on battery you don’t have to fiddle with iwconfig or rc.local (won’t work reliable anyway).

Open the file /etc/tlp.conf as root and change on to off in TLP’s configuration instead:


Reboot for changes to take effect.

I swear I documented a situation where an odd Atheros card was causing random freezes (fixable by module options) … I just cant find it…

That is only a small part, and importantly, missing the sections like ‘Network’…
(maybe because of the lowercase f instead of F … I was not sure if typo)

This might help:

tl;dr vendors using cheap IoT with $hitty support firmware in Linux. Nihil novi.


This is not related self with power saving setup. This is directly kernel and firmware crap things.

TLP should be set in /etc/tlp.conf

RUNTIME_PM_DRIVER_BLACKLIST="mei_me nvidia pcieport"


I add manually. the whole file its commented.

I’m trying this config

Thanks, also add to my tlp.conf

im waiting to see if crash or not

thanks you all, with this configuration and an update of the firmware

( firmware-6.bin_WLAN.RM.4.4.1-00288-QCARMSWPZ-1)

seems to be working.

Again thanks


The system keeps crashing (3 times today), I will start again to loop up for errors

Hello there, after a upgrade of linux-firmware the wifi stop working.
So i’m using a USB with a realtek chipset.

The system keep crashing, i’m thinking on battery issues maybe or some kernel failure.

Is there any change to test the battery or maybe see if the system run out of battery from journal or dmesg?

Please create new topic issue.
