Yeah the "inactive" warning isn't very informative.  I get that
message all the time when starting an interface in managed mode.

You start net.wlan0 in master mode with /etc/init.d/net.wlan0?  If so,
do you have a PSK?

hostapd doesn't report any error and I don't think it should.
Everything works fine as soon as I 'ifconfig wlan0 192.168.1.1' but I
know there's a way to assign that IP automatically, I've just
forgotten what it is.  My description above is the trouble I run into
when I try to set up that automatic IP assignment.  As long as I issue
ifconfig manually, everything works fine.

Is anyone here running hostapd?  It's the Gentoo+hostapd combo that
has me stumped.
