I am running Leopard 10.5.8 on a MBP
I am unable to access the "802.1X" tab in "Network Preferences". When I click on it, the tab turns grey, but no menu pops up. I tried doing a Safe Boot and changing settings there, but when I tried to save settings, the "Network Preferences" shuts down abruptly.
I did not have this problem until I tried to connect to a University Network, which has WPA2 Enterprise security and the need to create a new user profile in this "802.1X" tab to access the internet (ridiculous, isn't it?).
Please let me know if you have any suggestions.
