How to change your MAC Address

Media Access Control address(MAC)

Linux in General (3 Possible Ways):
sudo ifconfig wlan0 down
- turn device off
sudo ifconfig wlan0 hw ether XX:XX:XX:XX:XX:XX
- set the mac you want
sudo ifconfig wlan0 up
- turn device on
sudo ip addr
- show config
sudo ip link set dev wlan0 address XX:XX:XX:XX:XX:XX
- set the mac you want
sudo pico /etc/network/interfaces
- edit your network devices
- add hwaddress ether XX:XX:XX:XX:XX:XX to your device

After you change your MAC address, run sudo /etc/init.d/networking stop then sudo /etc/init.d/networking start

GNU Mac Changer: www.alobbs.com/macchanger
Install: Install: sudo apt-get install macchanger

macchanger -s wlan0
- shows the current mac on the device

macchanger -mac wlan0 XX:XX:XX:XX:XX:XX
- set the mac you want

You might want to add a script in the /etc/rc.local to automatically change your MAC Address everytime on boot.
