You have no idea how many networks I've found labelled "Linksys", "Netgear" and "default". Invariably, typing in http://192.168.0.1 will take you to its config page, and invariably, it's still using the default password. Occasionally, I've found "Apple Network 84357" (number is random).

People buy routers, connect them, and never set them up. If they only knew...

Tools of the trade: iStumbler and (if you know how to install it, and want to snoop a network) ethereal (must run as root).
