Home Network, Wellner

My I.S.P is Comcast. It enters my house through my dining room on the first floor of my hose. It uses a Modem/Router connected by Ethernet. The desktop in the dining room is connected by Ethernet cables directly. The printer, cell phones, laptops, and other computers are connected through wireless. The home phone and game systems are connected through Wi-Fi, along with a Blu-Ray player that can access Netflix Streaming and Pandora. When I learned about this, I was surprised to learn that my printer needed Wi-fi to functio.
