In FC2 I have it all in the ifcfg file for the wireless interface.
I imagine it is the same for FC3. Take a look at 
/etc/sysconfig/network-scripts/ifcfg-eth1 and see what it contains.

This is what my wireless ifcfg file looks like. ath0 because I have
the atheros chipset, which I have had no problems with. My laptop
and one of my pcs use atheros wifi.

DEVICE=ath0
BOOTPROTO=dhcp
TYPE=Wireless
ESSID=essid
RATE=Auto
IWCONFIG="key 123456789a"

You can also set other wireless things like

CHANNEL=
MODE=
PEERDNS=

Once you have everything set in the ifcfg-eth1 file
you should be able to do ifup eth1, or ifconfig eth1 up
and have the interface using dhcp.
