    vendor   = 'Atheros Communications Inc.'
    device   = 'AR5212, AR5213 802.11a/b/g Wireless Adapter'
    class    = network
    subclass = ethernet

If this adapter could work as a access point with WPA, 
could someone give me some hints about the settings?
If it can't work, could you recommand another PCI adapter?
Thanks in advance.
