How Should I Set Up My Home Network?

by Leo A. Notenboom

A home network allows you to share a single internet connection, as well as data and devices, between multiple devices. I'll review the basics components of a home network and some steps to take as your network grows.

Let’s say you just bought your second computer. Perhaps you purchased a new laptop, tablet, new machine for your spouse, or another machine for yourself. Maybe you want to connect your smartphone via?Wi-Fi?when you’re at home, to reduce the usage of your mobile data plan. Perhaps you got a smart TV, light switch, video-streaming?box, or?Echo?or Echo-like device.

Whatever the device, you want to connect it to the internet. It would also be?nice to share things, like printers or extra disk space, among compatible devices.

You, my friend, need a?LAN, or Local Area?Network. There are lots of ways to?set one up; I’ll review the basic setup for the most common case.

Already have a?network, but not sure how to grow it? I’ll look at that,?too.

First, let’s look at the two types of networks: wired and wireless.

Wired Ethernet

The basis of your LAN will be ethernet. That word has a very specific technical meaning, but in common use, it’s simply the technology behind 99% of computer networks: a way of transmitting digital data.

Most computers now come equipped with an ethernet adapter – it’s the squarish hole that accepts what looks like an oversized North American modular phone jack.

Your broadband internet connection — cable, DSL, or something else — will come into your home or business as a wire that connects to a device typically called a modem (again, technically inaccurate, but it’s the common term). The modem’s job is to convert the broadband signal to ethernet.

Ethernet

That ethernet is then connected to a router. The router can be a separate device, or, as we’ll see momentarily, can be in the same box as the modem.

Routers control two important things. First, they “route” information from the internet to your LAN, and among the devices connected to it. Second, as a side effect of the way routers allow devices to share an internet connection, most also provide a very efficient firewall, protecting the devices on your LAN from many internet dangers.

Each of your devices need an ethernet adapter. Most already have them. In a traditional wired LAN, an ethernet cable connects each device to the router, and another connects the router to the modem.

Important: Many ISPs provide a combined modem/router. That means the two separate devices — modem and router — are placed into a single box. Your internet goes in one connection, and you connect your devices to ethernet ports.
