Introducing WiFi Jammer..!!!!
So if someone (anyone) is abusing the internet wasting precious bandwidth for a Justin Bieber videoclips you could just jam their connection and stay happy with a full bandwidth just for yourself.
Works on any wifi network just put your mac address so that you are not disconnected from the wifi.
The good thing about this method is that you don’t even need to be connected to any wifi all you need to be is remain in its range and boom you now have the power of wifi jamming in your pocket. No one will be able to connect to any wifi when you are near. Just take this running in your school, college or just walk through your city and watch everyone annoyed.
