[Solved] wifi doesn't work Qualcomm Atheros Device [168c:0042] (rev 30

Just installed arch on my Acer e5-573G-37F8 laptop
Can't get wifi working.


lspci -k

I've got different firmware for ath10k

[alex@com ath10k]$ ls -la
total 28
drwxr-xr-x  5 root root  4096 Mar 15 09:08 .

drwxr-xr-x  3 root root  4096 Mar 15 09:08 QCA99X0

I do not have wifi interface. How do I know which firmware should I download and install to make wifi work?

I've found many links for downloading firmware from git https://github.com/kvalo/ath10k-firmware but I'm not sure which firmware I need to install.

Sorry for my English if I made mistakes. It's not my first language

Thank you for this link.
What I already did :
I've downloaded this file https://github.com/kvalo/ath10k-firmwar … .0-00267-1
renamed it to firmware-5.bin and putted it to newly created directory /usr/lib/firmware/ath10k/QCA9377/hw1.0/

Rebooted.

Nothing changed.

sad

I'm trying to install by yaourt -S ath10k-firmware-qca9377-git

but

==> Building and installing package
==> ERROR: Cannot find the git package needed to handle git sources.
==> ERROR: Makepkg was unable to build ath10k-firmware-git.

Well the PKGBUILD does other things with qca9887-git also - https://aur.archlinux.org/cgit/aur.git/ … rmware-git

I suggest you use makepkg or an AUR helper to make and install the package properly.  Also pacman will know about the installed files.

BTW I have the same card and it works here.

ahaha yes it worked after installing git

Thank you for advice because I thought that git package it is not the git itself but package of firmware.

I've made build and copied source to /usr/lib/firmware/ath10k
Rebooted
Nothing changed again.
there is no wifi interface.

What is wrong?

UPDATE: I've renamed file firmware-5.bin_WLAN.TF.1.0-00267-1 to firmware-5.bin, rebooted and interface showed up!!!

Thank You!

Well, you shouldn't have needed to copy anything.  I suggest doing a little research on the wiki about how AUR packages work, but in short if you used yaourt it would have built and installed the package without you needing to do anything else.  If you built it with makepkg the built package should be installed with pacman -U /path/to/package.

If the package installed with no error messages, then I'm afraid I don't have any other ideas.

Edit:  I see you solved it (kind of wink )  Please edit your first post and mark the title [Solved]

Re: [Solved] wifi doesn't work Qualcomm Atheros Device [168c:0042] (rev 30

Thank you SteveK! Now my wifi is working but I still get

dmesg | grep ath10k

[   10.241313] ath10k_pci 0000:03:00.0: Direct firmware load for ath10k/cal-pci-0000:03:00.0.bin failed with error -2

why does this message appear and can I rid of it somehow?

Glad it's working now smile

I get the same message but I don't think it's anything to be worried about.  I suspect this is from the linux-firmware package, trying to load first.  When it fails the firmware from the AUR package is loaded.  Notice it appears in dmesg in your first post too.

I've no idea how to be rid of it.

Edit:
Coincidentally, support for this card is now in the latest version of linux-firmware to hit the main repos.  You'll have to remove the AUR package in order to update.
