The security of WiFi routers has always been an area of concern since the time of their inception. There has always been a demand for a cross platform auditor which can check the safety of wireless routers. WiFi Auditor does just that and that too perfectly.
Using WiFi Auditor is very simple but you need to have Java running on your machine. If that ok, then you can just click on the compressed JAR file convert it to Executable format and start scanning with the help of the Auditor. But you should use it with caution.
WiFi Auditor can run Windows XP, Vista and Windows 7 and does not need a lot of memory space to run. If the network is not secure it will help you do that. And it should be used in a responsible way especially in private local networks.
