How do you install a network for a group of family computers?

Answer 1

I'll answer assuming you're using Windows based machines. The absolute easiest way is to buy a Router or Switch from a company like Linksys. A Router will handle outbound traffic, so you'll need that if you want to share broadband internet connectivity. Then you'll need a network connection for each computer you want to hook up. If the computers are close together, just run network cables to the router/switch, and set "Network Settings / TCP/IP settings to 'acquire an IP address automatically' ". That will get everyone on the network, and you could play games against each other, for example. If you want to share files, you need to right click on the folders or files you want to share, and click "properties" or "sharing" and open sharing to those files.

Use a Hub and the job is done...

Your ISP subscription will create only one IP address (unless you purchase more). Attaching multiple systems to your ISP modem using a hub or switch will create duplicate IP addresses on the network and nothing will work. The correct technique to get mom, dad, brother and sister to share one ISP subscription is to connect

modem---router---family computers

Each family computer will have an local LAN address (created by the router) and all systems may be used independently or simultaneously. As most routers available for home based systems are limited to FOUR lan connections, if you have more that four computers or need a fifth connection for a networked printer using IP, then just add a hub or switch:

modem---router--switch--extra devices

and the family computers can still connect directly to the router.
