1) It only affects the new unibody macbooks. All others work as expected.
2) PCs and other devices (such as iphones) work fine.
3) The symptom exists across our Aruba and Cisco wireless networks (!)
4) The mac reports that it is connected but sits with a 169.254 address.
5) We've observed this with 10.5.7 and 10.5.8. Most are at 10.5.8.
After working on this for a while, I stumbled across the following technique that worked fairly reliably to get the machine online:
1) Reboot (can't hurt, right?)
2) Try to connect to the PEAP network. Let it fail with the 169.254.
3) Connect to our guest network and obtain an ip address. (works fine)
4) Connect to the PEAP network. The machine will now connect properly.
Solved! Go to Solution.

Although it says connected when these devices don't have an IP, I do not believe they actually authenticated at all. Thus why they have the 169 address. I believe when you use captive portal, the mobileme cert is used to cash the keychain, and then when you go over to the PEAP ssid, it is now using that cert. I could be wrong here, but I think that was a problem with my macbook pro from a year ago.
Check your auth messages on the controller, or IAS (which ever you are using)and validate the station did send credentials.
I believe there have been recent updates that dealt with bluetooth and WiFi connections.

We have identified the issue and have a workaround.
The problem seems to be caused by the corruption of the profiles as they are stored on disk. On the affected macs, look in Network Prefs -> Airport -> Advanced -> 802.1x > Your Profile. If the "Wireless Network" pull-down is blank, you're affected. We've found that if you delete the profile under 802.1x,
delete the profile under Airport, delete the files as specified in the following URL:
... and then reboot, you can then re-create the profile and connect properly. If you then go back into the 802.1x profile and touch ANYTHING, the bug will reappear.
We've been able to get all of our previously affected machines online using this technique.

Is there a tool that will do this for every logout or login for multi-user machines?
