Wireless DIY – How to Set Up WPA2 Network!

For those of you wireless tinkers who need the best in wifi security, ComputerWorld has a great guide on how to set up WPA2 network.  I think this is a great way to “secure” your wifi network, especially since it’s already been proven even WPA can be cracked easily. – link

Step 1: Windows OS: First make sure your operating system is up to date. If you are running Windows XP, you’ll need service pack 2 and you’ll need to download the WPA2 patch that’s located here.

If you’re using a Mac, you need to be running OS X 10.4.2 or better. Apple calls its version WPA2 Personal. While Linux is outside the scope of this article, you can get more information here.

Step 2: Wireless Adapter: While you are updating your Windows OS, you might want to make sure that the wireless adapter in your laptop is also up to the task of supporting WPA2. The Wi-Fi Alliance maintains an online database of products that is somewhat difficult to use. Go to their Web site, check the WPA2 box and then select which vendor you are interested in.

If you have a built-in Intel wireless adapter, it needs to be running Intel’s ProSet version 7.1.4 or better, excluding versions 8.x. You can get more information on this page on Intel’s Web site.

Step 3: Wireless access point/router: Next, make sure your router/gateway can support WPA2. If you have purchased it in the last year, chances are good that it does, but you might need to update your firmware as well. For the Belkin Pre-N router model 2000, I needed to update the firmware to version 2.01. An older model 1000 didn’t support WPA2 and couldn’t be upgraded. How can you tell the difference when you are buying one? You can’t, other than opening the box and looking at the label on the bottom of the unit.
