So are you actually using your computer as an AP?

You have to.  WPA only works with a supplicant.  Yes, ubuntu should install
wpa_supplicant if it detects a wireless device at install time, but iirc it
doesn't.  <blatantOpinion>It shouldn't even _talk_ about as useless a

Well, networks _don't_ work right after booting - at the very least not
until /etc/init.d/networking runs.  If it's being activated by hotplug,
then it starts even later and if it's being activated by ifplugd (what I'd
do) then it's even later still.  I'm not sure how significant it would be
that it takes a minute - I guess it depends when you started counting :-)

I don't use either hotplug or auto.  I find it much more reliable to use
ifplugd.  When it detects either a linkbeat (on the wired connection) or a
connection to an AP it uses ifup to start the interface.  It depends
whether you're really using the machine as an AP.
