    Trouble with macchanger

    Hey, I am having trouble assigning a fake mac address to wlan0. This is what I do:-
    Code:
    ifconfig wlan0 down
    macchanger -r wlan0
    However I get the error : Can't change mac: interface up or not permisson: cannot assign requested address

  2. The commands are correct, but you might also try "/etc/init.d/networking stop", can you please post additional information: ifconfig, iwconfig, wireless card etc.
    Also, take a look at this, it might be helpful, http://www.debianadmin.com/change-yo...l-address.html

    it seems that i have to disconnect from my connection in order to be able to do the change
    if i'm still connected to my network it will not let me do mac change

    try disconnecting then bring down wlan0 and do the change

    Did you try to change the MAC not randomly, as in ">macchanger --mac 00:11:22:33:44:55 [interface]"

    No need to Switch off ur Wlan
    Just Stop Monitoring mode and than u can change ur Mac

    airmon-ng stop wlan0,,, this is stop ur Mon0 interface

    than simply random mac changer will work

    macchanger -r wlan0 (whatever u hav)
