WPA2 Enterprise network doesn't appear in WiFi list (OSX Mavericks)
Once you have joined the network by the method you list, open System Preferences and the Network Control Panel; select Airport on the left, and then click the Advanced button on the lower right of the Panel. Check the box next to "Remember networks this computer has joined" and then, if not already listed in the above list, click the plus ( + ) button on the left below the list, and add the network to your list of Preferred Networks. If it is a network you use often, then you'll want to order it near the top of the list. Then click the OK button, and then click the Apply button, and close System Preferences.
