Security set-up options

WEP and WPA-PSK both do basically the same thing to protect your wireless network. Each security scheme uses encryption, which scrambles the bits inside data packets to hide the information that travels across your network. However, WEP is a weaker solution than WPA-PSK, because it's relatively easy to steal a WEP key.

On the other hand, you can use WEP with virtually every Wi-Fi device under the sun, making it the best option for networks with older gear. If you have an older 802.11b device on your network, chances are it will support only WEP, which will force you to use WEP across your network even though your router supports WPA-PSK, since all devices must operate with a common security scheme in order to communicate with each other. I recommend that you use WPA-PSK if all of the devices on your network support it.
