Please try to configure the interface manually with ifconfig, rather than relying on /etc/netstart to do it for you. > If I disable encryption on the access point, it connects.

Yes. We need to determine where that code change might have occurred. What I am assuming for now is that you are using some crazy characters in your wpa passphrase and that netstart or something else is not processing them correctly, resulting in a wrong key being installed in the kernel. But that's just a guess. I don't have facts other than that msg 2/4 is failing. This symptom very strongly points towards a wrong WPA key. There is no other reasonable explanation I could think of. If you could tell us whether manual configuration with ifconfig works or not, that would help a lot to decide where to look next.
