How to Create a Network

The view from behind a typical Ethernet router

A network is used in the home or office to link a series of computers together. Once linked, computers can share an Internet connection and files, transfer to and from other computers directly and even stream media from one computer in the network to another. The most common standard for computer networking is hard wire-based Ethernet. The cable used for Ethernet looks like a heavy-duty version of a standard telephone cord, and you will find that most computers come preloaded with Ethernet-ready networking cards, as illustrated by the socket on their back or side panels.

Things You'll Need

• Modem with Ethernet output
• Power outlets to support all devices
• Ethernet router
• Ethernet cables

Instructions

1. 

   A larger router for business applications

   Connect your router to your modem via an Ethernet cable--the router should have a specific slot marked "Modem." Plug in the router's power and ensure that the router powers up and is taking modem signal. If your router came with its own software drivers and installation software, run it now before connecting the router to any of the computers to be networked. Follow the directions as they appear onscreen. In situations where you do not have any software, connect all of the computers that are to be on the network and run a networking configuration wizard. The process should be similar for most operating systems; in Windows, it can be accessed from the Control Panel. Some computers may auto-recognize an Ethernet router and will prompt you to join the network; simply follow the onscreen directions in these cases.

2. Configure your Internet connection settings if they were not changed automatically. To do so, access your Control Panel under the Network Connections icon. Different operating systems will have slightly different layouts. However, with some careful exploration, even laymen should be able to initiate a wizard to set up LAN Internet connections. Just make a note on paper of every setting you change in case you need to switch it back.

3. Determine what documents you want to share on the network and move them to a shared folder on your Network Places window. Different operating systems will have other methods of achieving this. In some cases, folders can be shared via the folder options. Every computer will need to have a shared folder before you can transfer files to and from computers over the network directly.

Tips & Warnings

• Consider paying a little bit extra for higher-quality cables. Cheap cables can have wires break internally, which will render the entire cable useless.

• When you order your router, ensure that you also buy the right number of cables of a suitable length for your application. When in doubt, give yourself a few extra feet of cable with which to work.

• Look for robust connectors, particularly for cables that will be handled frequently, such as those that will plug into laptop units.

• Store the manual for your router in case you need to make use of warranty or troubleshooting tips.

• Occasionally routers crash, just like any other piece of computer hardware. If you are having trouble with slow connection speeds, check the back of your router for a "Reset" button and use it.

• For business applications, or enhanced security home use, you'll need to password-protect the network during the setup phase. Strong network passwords should be eight characters and a mix of letters and numbers.

• Be careful when stringing wire though walls and vents. It's generally safer to affix network cable to the outside of walls with screws and metal straps instead of risking a melted cable, particularly in older buildings.
