Mac App: AP Grapher
Sunday, April 26, 2009 at 2:38AM AP Grapher is a freeware program for OSX that detects and displays wireless networks. AP Grapher consists of two main windows, the first window called the Scanner Window (the top right in the pic below) which shows the networks AP Grapher has detected and the second which is called the Grapher Window (the bottom left in the pic below) which graphs the network you are currently connected to. These two windows are shown below.

The first window (see below) which contains the different networks that AP Grapher has detected. There are several columns, These are Name (this is where the names of the wireless access points are displayed), Security, Channel, Signal, Noise, Best (which is the best signal strength received), Availability, MAC and Last Contact.
