The WNSQ-261ACN(BT) has an Atheros QCA6174A-5 chipset. From what I can tell kmod-ath10k will support it, but dmesg says:

Try this (tested on current master with SparkLAN WPEQ-261ACN(BT) - looks like same module, just a different interface: minipci-e vs. M.2):
cd /lib/firmware/ath10k/QCA6174/hw3.0
mv firmware-4.bin_WLAN.RM.2.0-00180-QCARMSWPZ-1 firmware-4.bin
wget http://projects.dymacz.pl/sparklan_wpeq-261acn-bt/eeprom_ar6320_3p0_NFA324i_5.bin -O board.bin
rmmod ath10k_pci
modprobe ath10k_pci
That worked for me:

Great 
Your card is in monitor mode, that might be the reason.
It works for me™ (LEDE 17.01.4, x86-64):
