I think I'm falling behind now. I launched it and then noticed it wasn't saving. I adjusted the g0/0 interface so I ran router> enable Router#config. Then I set the IP address via Router(config-if) and tried pinging 8.8.8.8. The output said it didn't recognize the host or protocol. I exited the configuration and tried again.
Router enable configuration commands. Enter one per line. CNTL/Z

It is for labs but maybe i was doing it wrong ?)
The configuration mainly appears this way, but I ran the Ethernet from the back of the modem straight to the Cisco router.
Your Cisco router is positioned behind the modem, using an IP route like 0.0.0.0/0 to 192.168.0.0. You can enter the command "dhcp-set-route" to configure it.
