The error number (13) is reported from access point, which means
"Responding station does not support the specified authentication algorithm"
from the 802.11 spec.

This is primarily due to AirPort uses "shared" authentication mode
whenever WEP is enabled, and the 802.11 framework doesn't support
the mode at this moment.

But I've heard that AirPort generates actual wep key from configured
"password".  So I guess you need to know the generated wep key somehow
once shared authmode is supported.
