This video takes you through the steps required to set up your own wireless home network.
A home network is a great way to get the most out of your internet connection. With a network you can split your connection across more than one PC, and with wireless, you can use your devices anywhere in the house. No plugs, no wires, no mess. You can also use a network to share files between computers and other devices without having to physically connect them together. To set up a wireless home network, you need an internet connection and an account with an internet service provider, plus an internet-ready device, like a computer. Almost all desktop and laptop computers made in the last five years already have WiFi technology built in, which means you can work on a wireless network. Very old computers and some desktop computers without WiFi technology built in will need a WiFi adapter to be able to work on a wireless network. You can buy one at an electronics store.
You'll also need a wireless modem router. This plugs into your home internet connection and transmits the internet over the airwaves around your home. Most internet service providers will include a wireless modem router when you sign up, but you should check this with customer service first. The first step in setting up a home network is to switch on the model router. This is like a beacon, or even a translator taking the internet signal from your phone line and broadcasting it throughout your home. When you first switch the router on, it will look for computers to connect to and make the internet available to those computers. You need to give your computer permission to join the network. A computer with built in wireless will have a switch or a light that indicates it's wireless function is active. You use your computer's operating system to connect to the wireless router. On a Windows PC, you'll find a list of available networks right here.
Your router manufacturer will give you a code called an SSID. This identifies your wireless network. It'll probably look like a fairly random string of letters and numbers, but you can sometimes rename it to something more sensible if you like, once you have it all set up. Click the name of the router as it appears in the list. If your router is already set up with wireless security, you'll be asked to enter a password too. All this information will be either on the bottom of your router, or on a small card provided by your internet service provider. The default password is often hard to remember, so you can change it to something that's more meaningful to you. It's a good idea to have these written down and stored somewhere handy and safe.
Your computer will display a small message indicating you are connected to your wireless modem router. Add other computers and devices to your router in the same way to create your wireless home network. When you're done, you can share files including photos and music between computers, tablets, and smart phones that are on the same network, as well as share a single internet connection among all your devices without a cable in sight.
