It would help to understand your configuration better.  I'm guessing
you have one of the following:

1) a cable coming out of your wall into a provider-supplied
cable-modem, with a cable coming out of that modem to your computer

2) a cable coming out of your wall into a provider-supplied
cable-modem, with a cable coming out of that modem to a consumer
router box that allows you to share that internet connection where
one or more computers (or tablets or phones or refrigerators or
whatever) are either hard-wired into that router or attached via
wireless.

3) a cable coming out of your wall plugs directly into a special card
in your computer.

In case #1 and #2, it should Just Work, as Ubuntu should use DHCP to
find the address that the cable company gives out.  Sometimes the
modem remembers the last device you plugged into it and will refuse
to give out a new DHCP address until the modem has been reset.

In case #3, it's a LOT more complex, so if this is freakishly your
situation, it might require a lot more technical work (and I'd be
flying by the seat of my pants)
