Kensington intros WiFi Finder: Small, lightweight, and useful? I don't know the price, I don't know when it ships, but it'll tell you when you're within sensing range of a Wi-Fi network (802.11b or g) using three lights to indicate signal strength. [via Cord Campbell]
Pretty cool device but the design sucks and its fairly large.
The design may suck and the size might be large but does it work?
Are there any alternatives?
Well it is only a reciever so it is not capable of relating whether or not the network is open or closed, I bet it is not completely immune to interference, and three LED's for signal strength is kind of shabby.
large? it's two inches by three!
