High-speed Internet connections are typically run through a cable, DSL (telephone line–based) or satellite. Whether it is one computer or a dozen, the basic principle is the same: A computer uses networking and router hardware to access the Internet through proprietary equipment. For the home, this equipment tends to be an Internet modem. The average user can set up a high-speed connection in about an hour.Instructions
Setting Up a High-Speed Internet Connection
1. Connect the modem to the wall adapter (phone, cable or dish). If it is a connection for one computer on DSL, isolate the phone line with filters and install any required drivers to the computer. Then wire the modem to the computer with the provided Ethernet cable. Cable and satellite will work in the same manner but do not require filters for other adapters in the home. Modems will require setting up the user name and password before they will operate, usually through an internal HTML page accessible by typing in the device’s IP address into the URL line of a browser program. See the manufacturer’s documentation for the device’s IP address and login information.
2. Connect a router between the modem and computers, if there is more than one computer. Routers can be strictly wired or wireless, but they will have ports in the rear for Ethernet connections labeled “WAN” and “LAN.” There may be multiple LAN ports, but there should be only one WAN port. Connect the WAN port to the modem’s Ethernet port, and the computers’ Ethernet cables to the LAN ports. Some routers may require some setup before they will work; check the manufacturer’s documentation.
3. Power on the modem, router and computers, in that order. The modem will log in to the Internet service provider’s computer system; then the router will log in to the modem and set up its own IP range. The router will then pass out IP addresses to any computers connected to it.
4. Test the connection by loading a webpage on all computers. If any computer cannot connect, check its network settings and hardware, and be sure the cables are properly plugged in.
