you should assign this interface an essid to match the AP.  If the AP
requires a key you will also need to assign the key for wlan0.

           ^^^^^^^^^^^^^^^^^^^^^^^^
This is the exact same inet addr as eth0 above.

You *must* use different addresses, and they should also be on different
subnets.

You do not say whether these addresses are assigned by dhcp or static,
but regardless of how they are assigned they must not be the same.
