Which command?

There might be several :)  Have you checked the handbook?

http://www.freebsd.org/doc/handbook/network-wireless.html

It contains several examples.  Try to follow them, and if they fail,
post the command and the errors that you get.

NOTE:
I am not an expert on wireless :(  Sorry, but if I had to configure
it, I would approach it via the handbook.  Then if this fails, I would
ask here or some friends :)

Regards,

Antonio
