Really all hardware may not support WoW even though the flag is set and the WoW working depends on your laptop, BIOS apart from the hardware.

I had tested it in quite a few of cards like AR9280, AR9285,AR9485 with wow enabled. Further the hardware was generic, with only quite a few changes needed between AR9002 and AR9003. thank you.
