Default [Q] How to temporary change MAC Address

Hello guys!
Do you know how we change the mac address on the note ii (am rooted with phoenix rom 4.3). I have seen a few tutorials here but unfortunately i havent managed to get it work. When i go to the terminal with busybox installed and type busybox ifconfig it says applet ifconfig not found. I had no luck also with apps found in google play. Any ideas?
