The interface is already up (has to be to authenticate), the event you
get at that point (just after the ~110ms delay) is for LOWER_UP really -
which means carrier_on() in the kernel I believe. At that point you'd
need kernel level tracing or messages to investigate.
Maybe something is waiting for a beacon there?
