WirelessNetConsole: Free Wireless Detector and Information

Publisher description: WirelessNetConsole is a small console application that dumps all current detected wireless networks information into the standard output. For each wireless network, the following information is displayed: SSID, Signal Quality in %, PHY types, RSSI, MAC Address, Channel Frequency, and more.

WirelessNetConsole is a console application, which means that you should run it in a “Command Prompt” window. When you run it, the list of all currently detected wireless networks is sent to the console output.
As with any console application, you can redirect the output into a file by using ‘>’ or ‘>>’ in the command-line:
WirelessNetConsole.exe > c:\temp\wn.txt
