That didn't help.

But that did. Both Macs and the XP box are now working fine.

Out of curiosity, is this considered a Mac bug for not
working with EAPOL version 2 correctly, or a hostapd
bug, for not failing back to version 1 if version 2
fails? Or a gray area, where it's just up for grabs?

Thanks, both for the software and the help.
