Wireless Network Watcher 1.47

Wireless Network Watcher is a small piece of utility software that scans a wireless network and displays a list of all computers and devices that are currently connected to it. This is a helpful way to find out if neighbors are "poaching" on your internet connection, or if hackers are "eavesdropping" on your online activity. This list is "live," so you can copy the details of the connected devices into another application, such as Excel or some other spreadsheet.

Wireshark 1.8

Despite being totally free to use, Wireshark is the world's foremost network protocol analyzer. This utility software lets you capture and interactively browse the traffic running on any computer network to which you are connected. It works so well that it is the de facto (and often legal) standard for this kind of analysis within many industries and educational institutions.
