[QUOTE="MacInWin, post: 1942244, member: 396914"] There are actually two components to the network interface from the provider (ISP) and your local network, either WiFi or Ethernet. The first is the modem, which converts the fiber optic digital signals to copper digital signals. Second is the router, which takes the signals from the ISP, through the modem, and connects them to your internal local network (LAN) into which your individual devices log, and from which they get individual addresses so they can talk to one another and share the LAN as it connects to the ISP network. Generally, most providers merge the modem and router in one physical device and label it the "router" for your network. However, fiber has the complication of converting glass to copper, so there may be two separate devices, one for the modem and another for the router. Here in my area, the one fiber optic provider uses an external modem, attached to the house outside where the fiber optic cable arrives. It then has an Ethernet cable that goes through the wall to a WiFi router, in the case of ths particular provider, and Eero router. From that WiFi would be spread through the house. I suspect your providers will do similar kinds of things for you. The beauty of the separate devices is that if there is a problem, it can be diagnosed to one or the other of the devices and replaced fairly easily. If you want Ethernet in your local network, you would have to provide it from the router to wherever you want it. Most, if not all, providers stop at the router, with the rest of the LAN being the customer's responsibility. [/QUOTE]
