NetStumbler is a tool for Windows that facilitates detection of Wireless LANs using the 802.11b, 802.11a and 802.11g WLAN standards. It runs on Microsoft Windows operating systems from Windows 2000 to Windows XP. A trimmed-down version called MiniStumbler is available for the handheld Windows CE operating system. The program is commonly used for wardriving, verifying network configurations, finding locations with poor coverage in a WLAN, detecting causes of wireless interference, detecting unauthorized (“rogue”) access points and aiming directional antennas for long-haul WLAN links. No updated version has been developed since 2005.
