A nice primer on how to hack into your neighbors’ WiFi network (assuming they’ve taken little or no security precautions) — and, by extension, how to do the equivalent of at least locking the doors of your own WiFi network.
The latter is nicely summed up in the last paragraph:
Since everyone isn’t as eager to share their network as I am, it’s only fair to explain that there’s an incredibly easy way to keep neighbors and drive-by geeks off your network. All you have to do is set a password that isn’t as obvious as “1234.” There’s an eye-glazing list of Wi-Fi security measures you can implement to block overachieving Russian teens from monitoring your keystrokes, but in real life the only people sniffing your wireless signal are jerks like me who need a place to log on until the phone company wires the apartment. An unguessable password sends as clear a message as a shot of Mace: Go find a Starbucks, creep.
