I don't see that this is possible using your router: the router would have to connect to the S3 via wireless (which its WiFi is on the LAN side, not the WAN side) or via USB--unless your router can establish a WAN connection over USB (I've never seen that).
As an alternative, you can tether one PC to the phone (via wireless or USB) and share that Internet connection--you'll have to disable DHCP on all other devices (router, cable/DSL modem) and renew IPs of connected clients.
It's a bit of a hassle, but that's all I can think of.
If the tethered connection is strictly for web browsing, you may be able to find a proxy server Android app and just point your clients to it OR run a proxy server on the aforementioned tethered PC and use that rather than changing DHCP servers/client IPs.
