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)
        Subsystem: AzureWave AW-NB037H 802.11bgn Wireless Half-size Mini PCIe Card [AR9002WB-1NGCD]
        Flags: bus master, fast devsel, latency 0, IRQ 17
        Memory at ddc00000 (64-bit, non-prefetchable) [size=64K]

        Capabilities: [160] Device Serial Number 00-15-17-ff-ff-24-14-12
        Capabilities: [170] Power Budgeting <?>
        Kernel driver in use: ath9k
        Kernel modules: ath9k

during latop startup the "wireless" led is turned off, kernel with udev load ath9k module

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.
