Does anyone know in terms of wiring when they connect via coax vs say Ethernet, can I change it myself later? I want to use Ethernet because I heard it's better and I'm wired for it, but my house is 3 years old and right now wired for Satellite so I have all good coax cable. Can just see them wanting to use the coax to make it easier for some reason. Wondering if I as a user can just switch it to Ethernet when they leave?
