Hi,
i have an asus laptop with following atheros wireless adapter:
03:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

but the wpa_supplicant daemon finally can't establish link with accesspoint (reports rf-kill? error).
manual wireless enabling (Fn key + F2 key) fixes wpa_supplicant problems.
it looks like the ath9k module doesn't enable some hardware parts on system startup / laptop resume.
i've tested this issue with 3.1.2 and 3.2.0-rc3 git kernel sources.
BR,
Paweł.

i will just try to recreate this issue, once i get access to Asus
laptop. there is no issues with external PCI extender + AR9285.
also please let us know if its AR9285 is working properly in some
previous builds.
also follow up with Peter Stuge's comments. apart from what Peter had
mentioned the only other thing i can think of is rfkill polarity for
you card may be '1'(while default is '0'). you can get this info with
the attached debug patch.
