Oh, and it is a matter of changing your default route to point to the router on the wireless interface.
A default route is set to a host (the router) on a local network. That host has an arp record that attaches it to an interface.
# route add default 192.168.1.1
To make your changes more permanent, you will have to work out how you are getting the default route setting currently, and fix that.
Oh, and if you have more questions, post a new thread asking your question. Thread hijacking won't get your question answered any faster.
