Imagine sitting in an area wich offers free Wi-Fi and your signal is weak. Everywhere you move to, your signal stays weak and those who work there are unsure how to help you. There are many tools to help find Wi-Fi networks and their names; if they are open or secured. Wouldn't it be excellent if there were a tool that shows you the location and direction these Wi-Fi networks are coming from?
Behold, the Xirrus Wi-Fi Monitor Gadget/Widget. If you are using Windows Vista or Windows 7, and have your gadgets on the desktop, this is one I recommend. This will show you the Wi-Fi networks in the current area, your current signal strength in percentage. It will also tell you what SSID you are currently connected to and your current IP Address.
