two things come to mind.

(1) "reboot" your cable modem (this usually involves simply
power-cycling it).

(2) did it "work before" but no longer?  in which case you might need
to call your cable company and battle your way to a tech support level
that has end-user-platform independent knowledge of how it all works
(like roadrunner).
