taking a cue from Josh, I just walked my block with KisMac sniffing the air. Only 23 networks advertised. The first three are mine, and number 3 is my neighbor to the back. 4 and 5 were ones I had not seen before, but the TiVo did when I plugged it in. Number 7 is the business office at Temple Beth Am, I assume: pretty strong if I could pick up where I was walking.
A bit worrying how many of them are using WEP. I assume anyone with no security turned on knows the risks, but I expect the people with WEP are operating under a false sense of security. Think they would take it badly if I ran aircrack on those networks and left them a note telling them how long it took to derive their key, with the key, and suggested they tighten up?
And only one named “linksys.” Excellent. I guess ACTIONTEC and 2WIRE are brand names as well, so points off to those people.
