Chernowski, Home Network

My internet comes in from the wall in my living room and my I.S.P. is Xfinity by comcast. It comes in through a coaxial cable that connects to our modem/router. The modem/router then connects to by desktop and home phone by Ethernet cables. The devices that are connected using wifi is two speaker systems, a game system, a printer, cell phones, tablets, and laptops. I learned that your information will never go away if you post something and it can be used for or against you. I have not had a OMG moment and I plan not to. I would tell people to research their I.S.P.s, especially the yearly cost.
