Option Settings

• To get the optimum use from NetStumbler, many of the functions must be set up correctly. Many of those options are located in the Network Stumbler Options dialog box under View | Options. It has four main tabs and multiple suboptions.

• The Scripting tab controls the running of external script programs that may interface with NetStumbler.

• The MIDI tab controls the playing of MIDI musical notes.

• NetStumbler comes with ten sound files, which are installed by default. Each sound is associated within the program with a specific action. The standard sounds can be replaced with new sounds of your liking.

Disabling Network Protocols

• Disable network protocols to avoid any possible illegal actions.

• Disable TCP/IP via the command line on Windows 95, Windows 98/98SE, Windows ME, Windows 2000, and Windows XP using IPCONFIG.EXE.

• Alternately, disable TCP/IP via the graphical interface on Windows 95, Windows 98/98SE, and Windows ME using WINIPCFG.EXE.

• Disable TCP/IP on a PocketPC by manually entering an IP address of 0.0.0.0 and a subnet mask of 0.0.0.0.

Additional RF Equipment: Antennae and Cables

• An antenna in the 3dBi to 8dBi range is a good choice for WarDriving.

• A Magnetic Mount makes placing and using the antenna on a vehicle very convenient.

• A pigtail is needed to connect the wireless card to the antenna in most cases.

Using a GPS Receiver with NetStumbler and MiniStumbler

• GPS receivers calculate your position using triangulation from satellite signals.

• NetStumbler uses the GPS information to log the user’s location when a WLAN is detected.

• Both NetStumbler and the GPS must be configured to communicate with each other.

• The GPS must be set up and properly initialized before being used with NetStumbler.
