ath9k is a well supported driver in Linux. Present in kernel since 2.6.
(https://wireless.wiki.kernel.org/en/users/drivers/ath9k) Card is 5+ year old
implementation.
Tested and working in a Fedora-25 LiveCD without any additional configuration.
(Kernel 4.8)
In Qubes 3.1, added as PCI device to a Fedora-24 TemplateVM. (Kernel 4.1) ath9k
driver is correctly loaded but device does not show up in `iwconfig`.
