NetStumbler (also known as Network Stumbler) 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
  • Aiming directional antennas for long-haul WLAN links

No updated version has been developed since 2005.


  • InSSIDer was created as an alternative to Network Stumbler for the current generation of Windows operating system, but it's no longer free.
  • Kismet or LinSSID for Linux, FreeBSD, NetBSD, OpenBSD, and Mac OS X
  • KisMAC for Mac OS X
  • Vistumbler was created as an Open Source alternative which initially supports Windows Vista (hence the 'Vis' in the name of the program) and later supports newer Windows releases
  • WifiInfoView was created as a free alternative to the paid InSSIDer on Windows
