5 Tips For Upgrading To WPA2 Security

Why upgrade? Chances are you have bought something online with a credit card, used internet banking, or dealt with confidential information on your computer. If you use a wireless router with anything less than WPA2 encryption, your information may not be as secure as you think.

“WPA2 security is definitely worth the modest amount of effort required to set it up. The original WPA security standard can be cracked with relative ease unless you use a passphrase that is longer than 20 characters and is not merely composed of words that can be found in a dictionary.” [Quote from the PC World article: Wireless Tips: Your Wireless Network Needs a Security Update]

1. Check current devices for compatibility. Your router and wireless network card may already support WPA2; Google your devices and find out. If they do, download the latest drivers for your wireless network card and update the firmware on your wireless router (very easy to do, but follow the manufacturer’s instructions carefully).

If your devices don’t support WPA2, and the security of the information transferred over your network is important to you, consider buying a wireless network card and router that support WPA2. Most recent wireless devices have WPA2 as standard.

2. Download the WPA2 Hotfix for Windows XP. This threw me when I was setting up my network. You need to download this hotfix or WPA2 will not work. It’s that simple. The hotfix is #KB893357 available from the Microsoft Web site.

3. Set a strong password for both network key and wireless router. What’s the point of all this if you set a one word password? So make it greater than 20 characters, consisting of numbers, uppercase and lowercase letters, and obscure characters such as @ and &. Randomize it — be creative. Get your pets to walk on your keyboard. Just don’t be predictable. Pretend you’re Jack Bauer and this is a matter of national security.

4. Don’t bother with MAC filtering or Hide SSID. They add little or nothing to your security. Unless you have a specific reason for doing so, activating them generally only makes your life more stressful.

5. Use TKIP & AES encryption when selecting the encryption settings on your wireless router and on your computer; select WPA2-Personal with TKIP & AES encryption. This is a very high level of security for today’s standards.

HOT TIP: WPA2 Personal is the one to use unless you run a large enterprise.

BONUS TIP: Use the Windows Wireless Assistant built into Windows rather than the one your wireless network card came with. It generally works with less conflict and generally uses less system resources. It’s one less “Yet Another Program That Wants To Load At Startup.”
