I have a new Acer Aspire VN7-591 Laptop with a Qualcom Atheros QCNF344
wireless chip, which is shown by lspci as:

Qualcomm Atheros Device 003e (rev 20)
Subsystem: Foxconn International, Inc. Device e08e

I have installed the linux-next kernel from today 8:00 UTC.
I was able to load the ath10k_pci driver, but the driver complains about
missing firmware.
I installed a firmware from here:
under /lib/firmware/ath10k/QCA6174/hw2.1/
But also the card is not working.
The output from dmesg is:
[ 9360.538767] ath10k_pci 0000:07:00.0: pci irq msi interrupts 1
irq_mode 0 reset_mode 0
[ 9360.788588] ath10k_pci 0000:07:00.0: Direct firmware load for

[ 9362.729156] ath10k_pci 0000:07:00.0: could not probe fw (-110)

I would like to know, as Austin Hendrix wrote it at 8 Feb 14:12 2015
too, where can I find the firmware on the
internet / my Windows7 partition and how can I prepare the needed files.

Many thanks,
