I've got this miniPCIe wifi module which comes with Asus motherboard:

$lspci -vnn
02:00.0 Network controller [0280]: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter [168c:003e] (rev 32)
	Subsystem: ASUSTeK Computer Inc. QCA6174 802.11ac Wireless Network Adapter [1043:86cd]
	Flags: bus master, fast devsel, latency 0, IRQ 125
	Memory at f7000000 (64-bit, non-prefetchable) [size=2M]
	Capabilities: <access denied>
	Kernel driver in use: ath10k_pci
	Kernel modules: ath10k_pci

But I have problem to get it working. It look that wlan is there, but doesn't receive any SSID.

$ip a
4: wlp2s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
     link/ether c8:ff:28:0e:5e:e1 brd ff:ff:ff:ff:ff:ff

$iw dev wlp2s0 scan
  returns nothing.

I have Ubuntu 16.04 with this kernel:
$uname -a
Linux dole 4.4.0-42-generic #62-Ubuntu SMP Fri Oct 7 23:11:45 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

I've tried both distro and git FW (probably the same), but it still complies about firmware-5.bin. I thing there is 
missing subsystem ID in board-2.bin as I mentioned there was added some other subID 2 months ago.

$dmesg | grep ath

Can anybody help me, please? I'm totally new in this binaries so I don't know how to add it.
Thanks Jiri
