My Ethernet cables in my house are not live. Only one of them works so I can’t set up my extender only my router. I need more wifi coverage. Can Verizon make my current Ethernet cables live?
I assume your "live" ethernet cable is the one from your ONT to your router? If so for the other ones to be "lives" you need to buy a Unmanaged Network Switch and hook up your cables to it and connect it to your router. Fios sells one for cheap.
