You may have nothing to do (on the Ubuntu side.)

I read your post and can't tell much about your internet connection. It sounds like you have the cable modem but no router. Without that you won't get a connection without doing a back flip. Here it is.

1. Power down the cable modem.
2. Plug in the next machine that is set to DHCP its settings.
3. Power up the cable modem, wait for it to finish, boot the next machine.

That means that your service may be LOCKED onto that other machine's MAC address. There's little we can do with that so ask if you can duplicate your other machine's MAC address to this machine in Ubuntu.

Sorry but what a MAC address is, is widely documented. As this is all volunteer you'll research that as needed.
