I am contemplating upgrading from 50/50 to Gigabet internet and understand I need to switch from COAX to Ethernet. Without someone from Verizon coming to make the connection (and without an Ethernet jack), can I simply run an Ethernet cable from the outside ONT box into the house to connect to the new modem/router? Or is it more complicated? Do I need an Ethernet jack or something else? Thanks for any advice!
