Wireless does not work after update [SOLVED]

Hi everybody!

I have the following problem, my wireless connection stopped working after a linux-firmware update.
The latest linux-firmware update (20181218) still does not work.

I temporarily made a downgrade to lxfw-20180825 (with wire) and I ‘ignore’ it in pacman.

How can I fix the problem?

Info:

$lspci -k
03:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 30)
Subsystem: Lenovo QCA9377 802.11ac Wireless Network Adapter
Kernel driver in use: ath10k_pci
Kernel modules: ath10k_pci

Thank you!!

Re: Wireless does not work after update [SOLVED]

Check which firmware is loaded when it works and when it doesn't and file a bug against the firmware providing some "minor" details like eg. dmesg?

Re: Wireless does not work after update [SOLVED]

ath10k/QCA9377/hw1.0/firmware-6.bin doesn't exist in the older package, but in the newer one. It's then loaded and apparently spoils your device.
So you can delete that file, see whether things work again, noextract it ("man 5 pacman.conf") and if thing s work again, complain to the author, https://git.kernel.org/pub/scm/linux/ke … 2be48c73b1

(I've no idea about the proper approach here, the guy works for qualcomm and provided all firmwares, so in doubt just dm him)

Re: Wireless does not work after update [SOLVED]

I would suggest ath10k@lists.infradead.org or linux-wireless@vger.kernel.org with a CC to valo@qca.qualcomm.com.
Would also suggest trying linux 4.20 with linux-firmware-20181218.

Re: Wireless does not work after update [SOLVED]

Hi Seth!. I replaced the file firmware-6.bin with the firmware-5.bin  and now it Works!!

Hi logs! Is probably that in kernel-4.20 this problem is already fixed, but I prefer to continue using LTS versions.

Thank you very much everybody!!!

Re: Wireless does not work after update [SOLVED]

linux-lts is moving to 4.19.13 hopefully it should be fixed there for you as well as in linux which is now on 4.20.
