Iwi, wireless bad behavior

Hi,

If you get the wep key (or network name) wrong when configuring iwi
network drivers the card becomes useless until you reboot. This is
annoying when at a friends house and I mistype the key for example. I
have tried taking the interface down and back up, it makes no difference.

Is there a way of resetting the card altogether?

Have you tried pulling it out? That usually fixes my zyd(4) (though it
has other problems than yours).

maybe netstart(8) can help? I used when trashing my wireless
configuration. Quoting from netstart(8):

After the system is completely initialized, it is possible to start a
newly created interface or bridge(4), or reset an existing interface to
its default state, by invoking the following, where foo0 is the interface
or bridge name:

# sh /etc/netstart foo0
