The Wi-Fi Alliance is launching a campaign to urge consumers to configure routers and devices to use WPA2 (Wi-Fi Protected Access 2) on all their wireless Wi-Fi equipment.

"Wi-Fi security has gone through some evolutions over the years and WP2, which has been around now for a few years, is the latest and greatest in Wi-Fi security," Kelly Davis-Kelner of the Wi-Fi Alliance said in this podcast interview.

WPA2, which offers government- and enterprise-grade security, is available in all products that the alliance has anointed as "WiFi Certified." The security standard replaces the original WPA and has stronger security than WPA and other protocols, including WEP (Wired Equivalent Protocol), which is still an option with most routers. WEP was introduced in 1997 and was largely supplanted by WPA and WPA2.
