That reads as if you have an ADSL (or perhaps cable) modem into a desktop PC, with a router going to the same PC, and a notebook PC trying to get WAN access from the router.
Which simply won't work. If that's an ADSL modem, lose it and replace the router with a modem/router. If it's a cable modem, stick it into the router, not any PC. Then you'll be most of the way there.
