Hi!
I use Wifite 2. Wifite 2 is the new version of wifite. It's a script that can be used for WEP cracking, WPA cracking and WPS cracking with reaver. It's an alpha version but i tried it and it work perfectly. I think that these may be better because is an AIO script written in python. For more information read "New Version":
