How to Enhance and Secure Your Wi-Fi Network

Easy-to-implement strategies for staying connected and secure on a home or public Wi-Fi network.

Track Intruders on Your Home Wi-Fi Network

Strangers may be lurking on your home Wi-Fi network. Don't assume that you are protected just because you have Wi-Fi encryption. Encryption--especially WEP--can be cracked. And even MAC-address filtering can be spoofed. To give interlopers the boot, download and install the free version of Network Magic. The program shows you a map of all of the computers, media servers, printers, and other devices connected to your network. Any listing that you can't identify is a potential intruder.
