Detect Wireless Local Area Networks (WLANs) using 802.11b, 802.11a and 802.11g

The program can come in handy if you are using a WLAN and you don't have signal or it is not working properly.

NetStumbler is a tool for Windows that allows you to detect Wireless Local Area Networks (WLANs) using 802.11b, 802.11a and 802.11g.

Here are some key features of "NetStumbler":

· Verify that your network is set up the way you intended.
· Find locations with poor coverage in your WLAN.
· Detect other networks that might be causing interference with your network.
· Detect unauthorized "rogue" access points in your workplace.
· Help aim directional antennas for long-haul WLAN links.
· Use it recreationally for WarDriving.


Requirements:

· The Proxim models 8410-WD and 8420-WD are known to work. The 8410-WD has also been sold as the Dell TrueMobile 1150, Compaq WL110, Avaya Wireless 802.11b PC Card, and others.
· Most cards based on the Intersil Prism/Prism2 chip set also work.
· Most 802.11b, 802.11a and 802.11g wireless LAN adapters should work on Windows XP. Some may work on Windows 2000 too. Many of them report inaccurate Signal strength, and if using the "NDIS 5.1" card access method then Noise level will not be reported. This includes cards based on Atheros, Atmel, Broadcom, Cisco and Centrino chip sets.
