If both interfaces are on same network, metric can't help you... You
must use "ip rule" and "ip route" without default route to solve your
problem.
man ip
and contact me (us) again if you have problems.
For example:
# eth1 = wired
# eth2 = wireless
/sbin/ip rule add prio 50 table main
/sbin/ip route del default table main
/sbin/ip rule add prio 201 from <wired_ip>/32 table 201
/sbin/ip route add default via <wired_gateway> dev eth1 src <wired_ip> proto static table 201
/sbin/ip route append prohibit default table 201 metric 1 proto static
/sbin/ip rule add prio 202 from <wireless_ip>/32 table 202
/sbin/ip route add default via <wireless_gateway> dev eth2 src <wireless_ip> proto static table 202
/sbin/ip route append prohibit default table 202 metric 1 proto static
/sbin/ip rule add prio 222 table 222
/sbin/ip route add default table 222 proto static nexthop via <wired_gateway> dev eth1 weight 2 nexthop via <wireless_gateway> dev eth2 weight 1
