I have a wireless Atheros AR9271 chip , USB or acts like USB, on an MSI MPOWER motherboard dating to May 2013. FreeBSD has no driver for this; I was able to use Hiro H50191 USB wireless adapter, driver rsu, though it sometimes drops the connection especially when I have it running for a long time. Currently on NetBSD, there is an athn driver, but booting hangs unless I disable athn. Previously on NetBSD, most of the time it would fail to load the firmware, but I have had some times where I was actually able to get an internet connection with this wireless adapter. Last experience I have with OpenBSD is 5.4, from liveusb-openbsd.sourceforge.net, now far outdated. This OpenBSD had both rsu and athn drivers, but neither one could load the firmware. You could try to port from either NetBSD or OpenBSD. On NetBSD I use re driver for Ethernet Realtek 811E/8168. Tom
