my PC has a Qualcomm Atheros QCA9565 / AR9565 wifi card and Mint 18 installed.
The wifi signal is very poor and unstable connection, less than 50% if PC and router are very close (1 metres), no signal and no connection if PC and router are more distant (5 metres).
It is impossible to use it.
Some info on my PC:
