Trying to setup wifi

I have recently installed arch linux and I am having some issues with setting up Wifi. After completing installation and rebooting arch I couldn't connect to wifi, then I discovered I am missing wifi interface.

So here is what I have.  Running  lspci -v  shows me this:

        
Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)
Subsystem: AzureWave QCA9377 802.11ac Wireless Network Adapter
Flags: bus master, fast devsel, latency 0, IRQ 131
Memory at ef200000 (64-bit, non-prefetchable) [size=2M]
Capabilities: <access denied>
Kernel driver in use: ath10k_pci
Kernel modules: ath10k_pci

and " ip link " shows me this:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 88:d7:f6:91:a3:5b brd ff:ff:ff:ff:ff:ff

Will appreciate any help to resolve the problem.
Thanks in advance.

Re: Trying to setup wifi

Post your dmesg, there might be some info on why ath10k fails to create an interface. Did wifi work during installation?

Post your dmesg, there might be some info on why ath10k fails to create an interface. Did wifi work during installation?

dmesg was very long so I uploaded it on github for preview https://raw.githubusercontent.com/Kouha … ster/dmesg

Wifi worked during installation, but after I rebooted it stopped working.

edit: here is lines where only ath10k_pci is mentioned:

Re: Trying to setup wifi

Two things: Set up your microcode updates and why are you using the LTS kernel? Particularly the ath10k module has seen a lot of work in more recent kernels that is not going to be backported to the LTS kernel, the current LTS kernel is a year old from a hardware support / compatibility POV.

Edit: Ah seems to be a known issue with current linux-firmware, see above

Re: Trying to setup wifi

If you delete /usr/lib/firmware/ath10k/QCA9377/hw1.0/firmware-6.bin then reboot is the dmesg output the same?  (To restore the file pacman -S linux-firmware)
