UsageEdit
iStumbler uses the AirPort card built into Macs. It automatically scans for Wi-Fi and WLAN networks,<ref name=":1" /> and can also detect Bluetooth, Bonjour, and other AirPort networks.<ref name=":0" /> The software shows a graph which displays the network name, the type of security, the vendor, the signal, the channel, and the MAC address of listed networks.<ref name=":3" /> A graph showing the history of signal strength can also be displayed.<ref name=":2" /> It can be used to join listed AirPort networks without configuration and to join Bluetooth networks as well.<ref name=":0" /> It uses GPS data to display the coordinates of the computer being used and nearby Wi-Fi points.<ref name=":4" />
iStumbler works by sending out probe requests to all available access points and displaying the information received from those requests.<ref name=":0" />
