You can't combine "use DHCP" and "use this SSID" in /etc/rc.conf .
To do both, you need to create a startup script that sets the interface
options (ssid / wep key / etc) and then just set /etc/rc.conf to use DHCP.
In /etc/rc.conf put this :
Then place this in a file called /etc/start_if.ath0 :
ifconfig ath0 ssid "some network" wepmode on wepkey 0x1234567890123
--- end of /etc/start_if.ath0 ---
The RC scripts will now first execute /etc/start_if.ath0 on boot, and then
to get an ip address on the interface with dhclient.
Obviously, your file would be /etc/start_if.fwe0.
