WPA2

With support from Microsoft for WPA2 on Windows XP Service Pack 2, you can secure your wireless network even further. Read this article from the Cable Guy explaining WPA2. I have already come across the 3Com wireless switches wx1200 and wx4400 supporting it. I have even come across a solution for a Leveno (former IBM) ThinkPad T42, supporting it on Windows 2000 Professional! It consists of a driver and the Access Connections package.
