If you've ever wanted to see who and what devices are connected to your wireless network, try using the free Wireless Network Watcher utility. This utility displays the IP address, Device Name, Mac Address,
and other information about each of the devices that are connected to
your wireless network. In addition to being able to scan your network
for all devices connected to your wireless network if you run this tool
in the background it can also notify you any time a new device connects
to your network.
Tip: If you're concerned about who's on your network because it is unsecure see our steps in making your wireless or WI-FI network secure.
