Get a new "computer man" when you say you have a new modem, are you talking about a DSL modem? if you are connecting your network card plug (ethernet) into your router's LAN interface, does that work with the configuration in step 3, click start, run and type cmd and click ok. then type ipconfig. paste the results of that command here.
