Wi-viz

Running on a Linksys WRT54G or compatible router powered by the Linux firmware OpenWRT, Wi-viz places the wireless apparatus into a special monitor mode that doesn't interfere with the operation of the router. Here it sits, examining all wireless packets coming into the interface and extracting valuable information about the surrounding wireless infrastructure. With an intuitive Web interface, it exposes this information in a simple, easy-to-use, self-arranging graphical format.
