When I start capturing with

# wireshark -i wlan0 -I

it says: 

    The capture session could not be initiated on interface 'wlan0' (That device doesn't support monitor mode).
    
    Please check that you have the proper interface or pipe specified.

also setting before

# ifconfig wlan0 monitor

does not help and does nos say anything.

# ifconfig wlan0
wlan0: flags=48843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,MONITOR> metric 0 mtu 1500

    vendor     = 'Qualcomm Atheros'
    device     = 'AR9462 Wireless Network Adapter'
    class      = network

Any ideas?
