Part 1 (read part 1 of wireless home network here) covered getting wireless access point. Now, it is time to setup security, and connect to the computers.
Wireless Security
Worried about security? You should be, but much of what you have heard is either old news, or it won't apply to you because you are smart enough to read BrightHub.com.
Much of the negative security talk comes from the early days of Wi-Fi. The original wireless networks used the now discredited WEP protocol for security. WEP is easily broken by hundreds of freely available tools. However, a new standard called WAP is available on all equipment these days. Using WAP solves lots of problems.
Another issues is that many users never changes the default settings that come with their wireless hub or router. They just plug it in and go. Make sure you take the time to set your own network name and password to eliminate these problems. It's easy. Chances are it's on the map-like Quick Start Guide that comes with your wireless router.
The other big issue with wireless security is hot-spots. These wireless networks are found all over the place, most commonly at coffee shops. In order to make them as easy to use as possible, they are setup with no security. That means that anyone can see what you are doing. However, this won't be an issue with your home network if you setup the passwords and other settings.
Wireless Network Cards
If your computer doesn't have wireless built in, or you just want a faster version, all you need is a wireless network card. For desktop computers you can get an internal card if you would like. More common for laptops and desktops is an easy to use USB card. It plugs into your USB port just like a printer. Set it up to match the settings you chose for your wireless access point, and you are off and running. Another benefit of a USB device is that you can move it between computers. That way, you can connect using your desktop on rainy days, and your laptop when the sunshine calls.
Your Wireless Network
Take your laptop out for a spin. The further you get form your WAP, the weaker your signal will get. Watch the little indicator to see where you can go. In the average house, you should be able to get pretty much anywhere, even outside!
If you aren't getting good range, try moving your WAP around your house. Higher is usually better, and a spot in the center of the house will allow more rooms to connect. Basements are always tough because they are underground and have thick concrete walls to help hold the house up. If you need connectivity down there, consider a wireless range extender which is just another wireless device that repeats the signal from the original wireless router to keep the signal stronger. If possible, try and locate your WAP away from other electronic devices especially cordless phone bases, and the microwave.
When you are done, go put on your most comfy PJs, grab a soda and head out to your deck. Enjoy working in your new home office annex!
