If you're tired of getting your WiFi connection
messed up every time someone microwaves a burrito or takes a call on the cordless, you might be interested in Wi-Spy, a
2.4 GHz spectrum analyzer for scoping out WiFi networks and related interference and viewing it all in a graphical
interface. That way you can know which channel is optimum as opposed to just guessing a number from 1 to 11. Created by
MetaGeek, they claim it's the cheapest device under $2500 with it's capabilities, and at a mere $99 for the USB dongle
we think they might just be on to something.
