If you  have your card properly configured as wlan0 through the
system-config-network gui then ifup wlan0 should bring it up and
ifdown wlan0 bring it down. 
Do you have a eth0 interface on you machine. We have found that even
if the machine is not connected with a wire the eth0 interface will be
brought up and prevent the wlan0 interface from coming up.

Now if anyone out there knows how to keep the eth0 interface from
coming up on boot even when there is no line plugged into it I would
like to hear about it.
