You probably already know that you shouldn't set up a WLAN (wireless local-area network) or Internet connection without protection in the form of encryption. What you may not realize is that WEP (Wired Equivalent Privacy) encryption is no longer enough in the eyes of most experts. WEP may discourage casual attempts to connect by nearby users that detect your WLAN's presence, but it won't keep out skilled and determined hackers. A better choice is WPA (Wi-Fi Protected Access), which adds several layers of protection beyond WEP. To use it though, you'll need WPA support in both your router or access point and your computer's wireless adapter.
