Just what the title says is happening. The WiFi in my house used to be WEP, but was changed to WPA2 to work with an XBOX wireless bridge. My laptop was made before the redesign, so there should be no solder problems with the Airport Extreme, and the connection was working perfectly before the security was changed. Any suggestions? I'm going to try to set the connection to WPA to fix it, but don't know if that will work.
