Problem with changing MAC address

[0xUndefined]

Hi, every one. I have a problem with changing my mac address. I tried to change it by commands:

ifconfig wlan0 down
macchanger -m 00:XX:XX:XX:XX:XX
ifconfig wlan0 up

At first,the mac address had been change.But then I tried to connect to the acess point, it didn't connect to the netwrok and the mac address change back to the one before spoofing.

Could anyone suggest me about this problem?

Thanks in advance.

If this is your AP then you need to reset it! you can't have an IP with 2 different Macs associated with it so when you try to access it have the Mac spoofed 1st then keep that IP & MAC together .
Or use static IP address with any Mac you choose but if running DHCP this will not allow it!

you should use:
macchanger wlan1 -m xx:xx:xx:xx:xx:xx
