set the essid again while dhclient is running -- this makes softmac
associate again and then it ought to work. Might be required yet
another time after getting an IP since the stupid dhclient likes to
turn off the interface all the time.
I've actually figured out where this bug is hiding. dhclient doesn't
modify the interface at all, even to set an IP. It just passes all
the info to /etc/dhcp3/dhclient-script (for Debian, may vary with
distro), which is expected to set everything up. There's some
documentation under "man dhclient-script", but it's a fairly self-
explanatory shell script. It looks like most distros use a slightly
patched version based off the example one shipped with ISC dhclient.
You could probably take a look in there to see where it excessively
ifconfig ${IFACE} up and ifconfig ${IFACE} down and patch it to do so
less often.
