WPA Assistant is a free wireless security software package designed exclusively for Windows 2000. Although WPA Assistant is neither as robust nor secure as Wireless Security Corporation's $5 per month WSC Guard, it may offer enough security for the wireless network of home users with non-critical data. Features Overview: Basic wireless network security for Windows 2000; Compatible with WPA-PSK, WEP, and Clear security modes; Simple user interface; 1 minute installation; 'Best Practices' security reminders. Windows 2000 users have not been able to use WPA-PSK (Pre-Shared Key) security. Users have to go through the hassles and costs of upgrading to Windows XP or installing a 3rd party client. With WPA Assistant, Windows 2000 users can freely and easily connect wirelessly in the following security modes: WPA-PSK, WEP, or Clear.
