<< Muadib: That will not work, his DSL "modem" is a PCI card
For any solution that does not involve the PC being on, you need to get an external DSL modem (ethernet not USB) and a ethernet router, or a cable/DSL router with the modem built in >>
Why exactly won't a router work?
You plug in a NIC, plug that NIC into the router and it should work fine.
