Unfortunately, many network cards and/or drivers from the Win XP era do not play well with WPA/WPA2 networks; connecting may require experimentation, patience, and/or cursing, or it may not be possible with your hardware. (SP2 with WPA updates supposedly will do the trick, but SP3 is a good idea anyway.) The exact interface depends on the software you're using to manage wireless network connections; refer to the summary at the top of this document and the help pages or other documentation for your computer.
See Windows XP WPA2-Enterprise using IEEE 802.1X | for one step by step guide that may help.

If you're familiar with wireless networks, the information in the "Summary" section is probably sufficient; if not, go to the Table of Contents below and find the section that matches your device's operating system.
