there is an app. my brother uses galaxy s and disconnects me from wifi sometimes to get the full bandwith. his phones is just rooted with 2.3 gingerbread. the name of the app is wifikill. i am connected to the wifi but i cant browse or fetch data.

what does this script do? can u please explain? does it do the same thing?

will i still be able to use yamas cleven and other attacks if i install this driver?
