This issue happens with both the Macbook and Macbook Pro. I noticed since the Leopard update 10.5.8 I was unable to connect and authenticate to any WPA Enterprise network with 802.1x authentication implemented. This specifically is happening to me at Purdue University and their PAL2.0 network. But I am sure it is happening on other 802.1x WPA Enterprise networks.
I have been going back and forth with Apple with this issue. I have been sending my logs to them and they are still working on it as I type this. The issue with the wireless seems to not only happen in Leopard, but in Snow leopard as well, so anything past 10.5.8. Here is a screencap that I found on D. M. Stanley’s blog at Link that shows the issue that is occurring.
I will keep anyone that wants to more about this issue up to date as much as I can on this issue. Apple should be giving me another status update in the near future.
