Final answer:
To set up a home network for modem internet sharing, connect the modem to the ISP and then to a router, which will serve as the central hub for both wired and wireless devices. Configure the router's Wi-Fi with a network name and password, and connect your devices to the network. Use the router's web interface for further settings adjustment.
Step-by-step explanation:
To set up a home network with modem internet sharing, you first need a modem that connects to your Internet Service Provider (ISP). The modem will typically connect to the wall outlet with a coaxial cable if you're using cable internet or a phone line if you're using DSL. Once the modem is connected and you have an internet signal, you connect the modem to a router. This router will be responsible for creating the local network within your home. It does this by assigning local IP addresses to each of your devices and allowing them to communicate with each other and the wider internet.
Most modern routers come with both wired Ethernet ports and wireless capabilities. For a wired connection, use Ethernet cables to connect your devices directly to the router. For a wireless connection, configure your router's Wi-Fi network by setting up a network name (SSID) and a secure password. Ensure that Wi-Fi is enabled on your devices and connect them to the router by selecting the network name and entering the password.
The router's settings can be adjusted by accessing its web interface through a browser using the router's IP address. Here you can manage security settings, parental controls, and other features like guest networks.
