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. You might get a reputation for being some sick laptop yoga freak, but isn’t free Internet worth it? Raise your laptop over your head, put it flat on the floor, tilt it sideways while leaning halfway out the window-get out the divining rod if you have to. Pay close attention to your laptop’s orientation-rotating your machine just a few degrees could help you pick up a network that you couldn’t see before. Sit near a window, since Wi-Fi signals travel better through glass than through solid walls. Since Wi-Fi and cell phone signals travel on a similar radio frequency, the same tricks you use for getting a better phone connection might work on your computer.

The best method to find some free wireless is to treat your laptop like a cell phone. “ Warchalking,” a technique for writing symbols in public places to alert neighbors to nearby wireless access points, is a cool concept that’s been undermined by the fact that no one has ever used it. If you want to find a Wi-Fi network, don’t start by looking on the sidewalk for chalk marks. But let’s deal with those abstract ethical issues later-you have important mail to answer! It is true that your surfing could cause the folks next door to break their service contract-many broadband providers do specifically forbid home customers from sharing a connection. In the end, it’s your neighbor’s Internet service provider-not your neighbor-who will pay for the added traffic, and the ISP has already factored a small amount of line-sharing into their price plan.
