o wifi connections available in Manjaro Linux

o wifi connections available in Manjaro Linux

[Xell Kim]

Hi! Sorry to interrupt you. I'm a manjaro user and met some problems
about the wireless configuration.
My new pc has Qualcomm Atheros QCNFA765 as net card and the default
driver for it in manjaro is ath11k. However, wifi service seems to be
unavailable and there's even no wirelessLAN interface in the rfkill
list. Besides, I should mention that the wireless service could work
with no problem under Windows system.

I've noticed an error info " mhi mhi0: Direct firmware load for
ath11k/WCN6855/hw2.0/amss.bin failed with error -2" but have no ideas
how to solve it.
I also tried modprobe ath9k but it didn't work. When I try to modprobe
-r ath11k_pci, my terminal got frozen for minutes and I had to stop
it.

More specific info can be seen in the link below:
https://forum.manjaro.org/t/no-wifi-connenctions-available/103091

I would really appreciate it if you can help!

You need to install the firmware, you can find the files here:

https://github.com/kvalo/ath11k-firmware/tree/master/WCN6855/hw2.0/1.1/WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3

https://github.com/kvalo/ath11k-firmware/tree/master/WCN6855/hw2.0

I recommend using kernel v5.17 to make sure everything works, you seem
to have older kernel so expect problems.

Apologize for not obeying the email etiquette.
I've updated my linux kernel to 5.17.0-1-MANJARO x86_64. Then I
downloaded the whole package /WCN6855/hw2.0  and cp them into
/lib/firmware/ath11k/ , whilst cp amss.bin and m3.bin to package hw2.0
from WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3 to meet the
demand.
After reboot, the error message changed to:

skipped because of a failed condition
check (ConditionPathIsReadWrite=!/).

which I think to be kind of weird, because I remained the exact
board-2.bin file of the repo in the package.
Then i tried to add ath11k & ath11k_pci into blacklist and modprobe
ath9k but it didn't work as supposed. One thing interesting is that
this improved my reboot speed to a big extent, which may also prove
ath11k still has some problems.

No worries. It's just important to have the discussions in the mailing
list so that others can see and participate.

Ok, so the board file for your device is missing. I'll try to find it. I
see that Alexander already opened a bug about this:

https://bugzilla.kernel.org/show_bug.cgi?id=215625

Let's continue the discussion there, I'll report my findings in the bug
report.

Can you file a separate bug report about that as well, please? Also try
to explain in detail how you see the slowdown, preferable with timing
info.
