NetStumbler and inSSIDer are cool wireless utilities, but Ekahau Heat Mapper takes things one step further. When you launch HeatMapper, you'll have the opportunity to select a map image - say, one you put together using Autodesk Dragonfly.

Wander around your location and click on the map every time you pause to take a reading, and HeatMapper rolls the collected data into a slick, interactive map. Hover over an access point, and the display updates to show its signal strength.

It's a handy way to help optimize your wireless network - or figure out who's AP you should jump on if your own router happens to take an unexpected dirt nap.

Have a Guinness on us, Molly!
