This home networking setup demonstrates how to connect a router with a built-in modem and access point to ensure good internet connectivity within a network. According to the diagram, you can connect up to four devices using a network cable and several wireless devices such as cell phones and laptop computers. We use a router assigned to us by our Internet Service Provider (ISP) in the basic network setup, making it less secure. This home networking setup layout is ideal for small houses with limited systems that do not want to spend much money on multiple routers and switches.
