[solved] Wifi firmware for Qualcomm Atheros

I cannot use wifi on my new Acer laptop.

Output of sudo lspci -v:

03:00.0 Network controller: Qualcomm Atheros Device 0042 (rev 30)
    Subsystem: Lite-On Communications Inc Device 0806
    Flags: fast devsel, IRQ 255

lsusb:

Bus 001 Device 002: ID 04ca:3015 Lite-On Technology Corp.

I already read through similar issues (e.g. 1), but it was not successful.

Installing kernel 4.3 did not help, modinfo ath10k_pci:

so as you can see, "42" is not available.

Any ideas what I can do? Thanks!

@CFP, I updated the repo for newer kernel 4.4-rc2. But this time you need to compile the kernel by yourself by applying the patch I mentioned in the updated README file.

Sooner there would be full support implicit in the final release of 4.4.

Thanks for your update!

[Nevertheless I'll wait until 4.4 is official (stable, not testing).]
