Network Stumbler (also known as 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:
- 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
NetStumbler's author, Marius Milner, maintains the occasionally-updated stumbler.net website where you can download the software. Another website, netstumbler.com, has more frequently updated information and wireless news.
Apparently, the project has been inactive for a while now, so it is unlikely that there will be a new version.
- Inssider was created as an open-source alternative to Network Stumbler for the current generation of Windows operating system
