I can't change my MAC address !

Hi everyone who read this !

Nowadays I would try some new stuff e.g. change my MAC address.

example:
sudo su
ifconfig wlan0 down
macchanger -s wlan0
(output:
Current MAC: 98:af:XX:5a:XX:XX (unknown)
Permanent MAC: 98:af:XX:5a:XX:XX (unknown ))
macchanger -r wlan0
(output:
Current MAC: 98:af:XX:5a:XX:XX (unknown)
Permanent MAC: 98:af:XX:5a:XX:XX (unknown )
New MAC: 0e:bb:XX:46:XX:XX (unknown))
ifconfig wlan0 up
ifconfig wlan0
(output:
ether 0e:bb:XX:46:XX:XX
I see my new MAC address for 1-2 sec, but after this type "ifconfig" and I get back my permanent MAC address... :(
ifconfig wlan0
ether : 98:af:XX:5a:XX:XX )

I am very grateful to everyone who can help me!
