Who Me Too'd this topic

We have an early FIOS installation that is Coax.  We have TV, Internet and Phone.  I want to move to Gigabit internet.  I saw that you can run an ethernet cable from the ONT to the router, and disconnect the coax cable.  However, all of our set top boxes etc are connected via coax...  My question is how do you move to ethernet to take advantage of higher internet bandwidth and maintain the TV and Phone services?

Thank you.
