If you select LEAP authentication on a Mac OS X 10.4.2 or later computer on which the AirPort 4.2 or later update has been installed, your authentication settings may be lost after restart, sleep, or location change. As a workaround, you should use the steps shown here, which will have the effect of configuring LEAP, even though you will choose WEP from the menu.
- Go to the Network pane of the System Preferences, show AirPort, and click the AirPort tab.
- Be sure the "By default, join" menu is set to "Preferred networks."
Note: If you don't have "Preferred networks" as a choice, this means that your 10.4 system was upgraded from 10.3, and that you're still using a Location imported from 10.3 (Panther). In this situation, you experience Panther behavior instead of new Tiger features. You will need to create a new location to utilize Tiger features and complete these steps.
- Click the "+" button.
- Enter the desired network name in the window that appears.
- From the Wireless Security pop-up menu, choose WEP Password.
- Replacing username and password with actual name and password, enter them exactly as show here, including both brackets and slash:
<username/password>
Note: Though there will not be any visible indication, this entry format sets the client to use LEAP rather than WEP.
- Click OK. Note: The network entry will appear in the table as "WEP," but LEAP will be used.
- Click Apply Now.
