No wifi on acer R13 372T (atheros QCA6174A)

My wifi does not work with any of the firmware / board combinations.
Here is my configuration:
Acer R13 372T (very new - maybe to new?), core I5 6200 with Atheros (QCA6174A Wireless network adapter, rev. 32, signature 168c:003e).
openSuse Leap 42.1 with kernel 4.1.12-default

I used Kvalo’s backport (4.2.6-1) to that kernel - installation worked without problems.
I copied the current firmware (firmware-4.bin and firmware-5.bin <as a copy of firmware-4.bin>) and board (board.bin and board-2.bin) <i.e. from ath10k-firmware-master.zip> to the right directory (/lib/firmware/ath10k/QCA6174/hw3.0) but I either get “firmware crashed” or

I also added:
echo “options ath10k_core skip_otp=y” | sudo tee /etc/modprobe.d/ath10k.conf
and really tried all firmwares…

Here are some output:

Thanks a lot for any help!! Pascal

BTW: As I do not have any internet access it is not that easy to update to a new kernel…

Hi and Welcome to the forum
That chipset has been around for some time according to;
https://wikidevi.com/wiki/Qualcomm_Atheros

Without all your tweaking (since the 4.1.x kernel module supports your device as far as pci id goes), what happened with the original openSUSE Leap 42.1 install and getting the device to work, as in visble and using the ath10k_pci module?

If you roll back to the default and disable (as a temporary test) your router security does it connect?

Hi,
I finally made my wifi running (Atheros QCA6174, rev. 32) using this hint:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1520343/comments/22
(I was sure that I tried every single combination of board and firmware. Maybe this was too much…)

Before that I updated to kernel 4.3.3 which was needed to fix a bug with intel graphic driver for the new Skylake processor…

The thread can be closed!
Thanks!
Pascal
