Wi-Fi Security's Personal Problems

    With security such an important concern for wireless networks, most new Wi-Fi gear has long supported Wi-Fi Protected Access 2 (WPA2), the latest standard for encrypting data sent over the air. As of this month, all Wi-Fi gear will, as the Wi-Fi Alliance is making WPA2 compatibility a mandatory part of its interoperability tests. But there are two kinds of WPA2, and most Wi-Fi phones and many other gadgets support only the lesser version, which was originally designed for home networks.

    When the Wi-Fi Alliance came up with WPA2, it segmented the market into two categories: WPA Enterprise and WPA Home. WPA Enterprise is a nearly complete implementation of the IEEE's 802.11i specification, aimed at large corporate networks that can afford RADIUS servers and full-time support personnel. WPA Home was a lighter subset, intended to be less secure, but simple to set up and used only in consumer electronics.
