I wrote a small shellscript (runs with bash) which enables me to switch from wm0
to ath0 or vice versa. It sets the correct routes, ip adresses, ... 

#!/usr/pkg/bin/bash
if [ "$1" = "" ]; then
        echo "Usage: hera.netconfig [wm|ath]";
        echo ""
fi

case "$1" in
        ath)    
                ifconfig wm0 down
                wpa_supplicant -c /etc/wpa_supplicant.conf -i ath0 -B

                ifconfig ath0 192.168.178.20 255.255.255.0

                route delete 192.168.178.0
                route delete default 
                route flush
                route add -net 192.168.178.0/24 -link ath0 -iface
                route add default 192.168.178.1 -link ath0

                ;;
        wm)
                kill `pgrep wpa_supplicant`
                ifconfig ath0 down
                ifconfig wm0 192.168.178.20 255.255.255.0

                route delete 192.168.178.0
                route delete default 
                route flush
                route add -net 192.168.178.0/24 -link wm0 -iface
                route add default 192.168.178.1
                ;;
esac

Maybe, it should be improved but it works...
