Using a router on broadband and/or wireless home networks

A network router is a small plastic and metal box that allows you build a home network simply. The home router serves as the core or "centerpiece" device of the network to which computers, printers and other devices can be connected. Networking with a router helps you to (for example):

* share files between computers
* share an Internet connection between computers
* share a printer
* connect your game console or other home entertainment equipment to the Internet

Installing a Network Router

Network routers receive their power from an ordinary home electrical socket. When powered on, a series of lights (LEDs) signify the unit is operating.

Network routers must be specially configured when they are first installed. Like computers and other devices on the home network, routers must be set up with IP addresses. Routers also offer optional (but strongly recommended) security features that can be set up if desired.

Routers contain built-in software to enable setup. You access this software through your Web browser on any computer connected to the router (see below).

Connecting Computers to a Router

The most basic use of a network router involves file sharing (copying files) between multiple computers. You do not technically need a router to set up file sharing (or a home network), but using a router greatly simplifies the task, especially when three or more computers are involved.

Home routers provide connection points (called "jacks") for you to connect computers with Ethernet cables. Plug one end of the cable into the router and the other into the computer's Ethernet network adapter. Wireless routers alternatively allow computers to connect via WiFi technology, if the computer possesses a WiFi network adapter. Networking With A Router - Broadband and Wireless Router Networking
