Ugh, is this using the install disk that came with your router? I never used one of them. Just do it manually, when you set up your router if your modem is connected all you should need to do is
1) connect the ethernet cable from your modem to your routers WAN port
2) connect your laptop to your router, wired connection might be necessary for setup
3) log into your router through your browser on the router or in the manual/box there should be something with the default IP of the router. Usually 192.168.0.1 or 1.1 or 15.1 (yes type 192.168.0.1 as if it was a URL in your browser, should go to the router)
4) enter the default password for the router.
5) set it up
