I've never had much trouble getting my netbooks, laptops, and other mobile devices to connect to my home WiFi network… or a neighbor's network for that matter. But what if you're ahem, trying to connect to an unprotected WiFi network down the block. While I don't think that's what EeeUser Forum member wakrein was necessarily going for with his WiFi mod, he I think he could probably pull it off.
Basically, wakrein modified his Asus Eee PC netbook so that he could plug in an external antenna. And then he found a directional antenna that's nearly as big as the one I have on my rooftop, threw it on a camera tripod, and now he can pick up WiFi signals from 100 yards away.
