That have sense only if station is associated.

I don't have ral(4) card so I can not comment on that. Alternative approach would be to explore AP settings. -- Paul _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
