I’ve just been on a short stumble/war-drive with my GPS unit for the first time, and here’s the results (using my standard format).

• 7 different SSIDs scanned
• 11 unique MAC-addressed nodes scanned
• 4 WAPs encrypted with WEP [36%]
• 3 WAPs using what appear to be default SSIDs [27%]

I’ve also included the actual Net Stumbler log (exported as wi-scan, with extensions [summary format]) for interest, which includes the co-ordinates of each point. At the moment I can’t map anything, so I can’t do a lot with the data, but it’s there if anyone else can do something with it
