Hmm.. That sounds odd..

Do you know whether the 'off' is the local configuration or AP value?

Yes, either the driver is somehow deciding to just want unencrypted
connection (I have no idea how ipw3945 driver does this) or the AP is
configured for some kind of mixed mode and the beacon frame is claiming
that it does not use encryption. For the first question, ipw3945
maintainers/mailing list would be a good target to ask this.. For the
second, Cisco AP has lots of odd configuration options, so who knows
what happens there. Maybe something related to guest mode configuration.
Is this AP using a hidden SSID?
