The start_if.wi0 script is started from /etc/rc.d/netif, and the
defaultrouter is used in /etc/rc.d/routing. These are run in separate
shells, so you can't set a variable in one and use it in the other. In
4.x your approach will work, as almost everything is run in the same
shell there.

I use 4.8R and DHCP and I had some trouble until I ensured that only
/etc/pccard_ether configured my wi card. It seemed not to like being
reconfigured and I had to fix it up myself later. I added this in
/etc/rc.conf: network_interfaces="lo0 fxp0", and also added a check in
/etc/start_if.wi0 to not set the wep key when already associated. (That
might cause problems if there is an AP with WEP off is nearby, but there
isn't in my environment.)

It still tries IPv6 twice, that doesn't seem to cause problems, although
I haven't tried IPv6 wireless for a long time.

If you're using 4.x, you should run pccardd. If you're using NEWCARD,
the default on 5.x (recognized by presence of the cbb0 device), you
should run devd instead.  The default /etc/devd.conf should cause
/etc/pccard_ether to be run on inserted network cards.

pccardd on 4.x at least waits for a few seconds after the card has been
inserted before initializing it, so you may need some patience.
