Gary,

Assuming you are doing "enterprise" (802.1X) authentication with your WPA setup, Apple Bug ID 5560437 identifies an issue where the Mac *sometimes* does not respond to EAP identity requests until the wireless interface is bounced. It is my understanding that the authentication client is *sometimes* not properly running after startup and bouncing the interface "resets" the authentication client (and is the current workaround according to Apple). Our experience has improved with 10.5.2, but we are still experiencing some problems and the bug is not resolved as my last bug update from Apple on 2/16.

We're seeing issues with Macs running the new Leopard (v10.5) OS. They would lose connectivity to our Cisco LWAPP (WPA authentication) wireless network. The only way to resolve it has been to disable and re-enable the wireless NICs. Apple came out with an OS patch (I think it is v10.5.2) that is supposed to correct some wireless problems, but I don't know yet if this loss of connectivity problem is one that got corrected.
