Question for facesniff

[yeemun]

Bought wifi kill yesterday , and testing facesniff now ...My phone is s2 running cm10.1 4.2.1 rom

My problem is when I press start , scan scan scan , nothing found , on stealth mode ,waiting 10 min , still nothing found

I'm test it , same network , use facesniff scan no profile found , if I'm use droidsniff (xda thread), around 1 min all website or facebook profile come out , it's work for me ...

Why facesniff won't work ....?

Thanks
