What wardriving approach gathers the most stations?
Easy: Go slow and stay off the superhighways. Consensus is that a speed of about 35 MPH is ideal for wardriving. Stumbler programs need some time to work, and if you roar past at 80, the more distant stations will not be within range long enough for the stumbler software to log them. My experiments also show that if you spend most of your wardriving time on limited access highways, you’ll miss stations compared to driving on surface streets. On a superhighway you typically go faster (unless you’re in LA, I guess) than surface streets, and you’re also farther away from buildings where the APs are and will thus miss more of them. Note well that Kismet is much slower to scan the full 802.11b channel space than NetStumbler, so if you’re wardriving with Kismet it’s even more important not to scream down the street at 75 MPH. Kismet, being fully passive, has to take time to listen for APs; NetStumbler, on the other hand, emits 802.11b probes frequently to speed of the process of AP discovery
