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.
*** Issue is not fixed with the most current update 10.6.2! ***
Update: 11-23-09 – Apple Contacted me and said there are no updates on this issue from the Apple Engineers so that means that they are most likely working on the issue because they would have said something by now.
Update: 4-13-10 – 10.6.3 may have fixed the issue..Click here to read more.
