Injection Wizard is an application for injecting traffic into WEP protected Wi-Fi networks, like aireplay-ng, but it's much more easy to use and it can work with worse conditions (for example, more interferences, weaker transmitted/received signals, more restricted access points, etc).
This application is distributed under the terms of the GNU General Public License version 2 (see the "license.html" file for more details) and has made use of two free software projects: Scapy and Python-Wi-Fi.
