What is MacStumbler?

MacStumbler is a utility to display information about nearby 802.11b and 802.11g wireless access points. It is mainly designed to be a tool to help find access points while traveling, or to diagnose wireless network problems. Additionally, MacStumbler can be used for "wardriving", which involves co-ordinating with a GPS unit while traveling around to help produce a map of all access points in a given area.

MacStumbler requires an Apple Airport Card and MacOS 10.1 or greater. MacStumbler doesn't currently support any kind of PCMCIA or USB wireless device.

Features:

MacStumbler only works with airport wireless cards, it does not (yet) work with any PCMCIA or USB wireless devices. Apple hasn't provide any information on interfacing with their airport card driver, so I had to reverse engineer the functions required to actually perform the scans. If you're looking for information about how to do the same you can download Apple80211.h. (Last Updated 6/3/02) In addition to submitting numerous parts of the header file, ragge has created an awesome command-line tool for accessing the airport driver.
