So i am trying to replace actiontec, and i know in order to do that, I need an ethernet instead of a Coaxial connection from the ONT to the router. Unfortunately, my house doesn't have ethernet wiring and my ONT is on the outside, making it pretty much impossible to route an ethernet cable unless I hire some people to do it professionally. Is it possible to use a custom router with a Coaxial connection with a modem or something??
