As discussed before about Netstumbler (A WLAN scanner), KisMAC (For MAC OS) and Kismet (For Linux) this artcile will discuss about inSSIDer.


inSSIDer is a award winning Wi-Fi network scanner that can be used for multiple purposes like to find out the intruder on the network, for troubleshooting the network and for hacking. It is an open source tools that previously available for Windows like OS only but now it is available for Linux too. It is a best alternative of Netstumbler.

• Filter access points in an easy-to-use format

• Export Wi-Fi and GPS data to a KML file to view in Google Earth.
