Nobody wants eavesdroppers on their wireless network and it pays to keep an eye on who is connecting to it. There are various ways to do this but a very easy approach is to use a little program from Nir Sofer called Wireless Network Watcher. Like most of Sofer’s free utilities, it requires no installation and is a portable application. It isn’t an elaborate network tool but it is a very simple way to list all computers and devices that are currently connected to your network. The interface is shown below.
A description and download link are at this page. The utility works in Windows 2000, Windows XP, Windows Server 2003/2008, Windows Vista, and Windows 7.
