If you already have a wireless router, all you have to do is to turn it into 
an access point to your internal lan. Disable its DHCP server, assign a free 
LAN IP to the router LAN ethernet,plug one of its LAN ports into your switch  
and assign free LAN IPs to the wireless cards of your LAN machines.

That's what I did here at home and works like a charm.

If you need a DHCP server you have to set it up on the FreeBSD router.
