Modifying tamulink-WPA in Windows XP
Document ID 850
Introduction
Tamulink-WPA is a wireless network that allows for greater flexibility and security when accessing the campus wireless network. WPA utilizes the 802.1x wireless technology. This document will detail how to configure Windows XP to connect to this network.
Changes implemented on the tamulink-WPA network on March 10, 2008 require users to modify a few things in Windows XP.
Modifications
If you have previously configured your Windows XP machine to connect to tamulink-WPA, then you should get the following message [fig. 1] when you try to connect for the first time again.
[fig. 1 - Initial Message]
When you click on the message, you should get a box that asks you to validate the new server certificate that contains either "Go Daddy" or "Valicert" in the name [fig. 2]. Press OK.

Your computer will now connect to tamulink-WPA, but there are additional steps required to prevent this box from appearing each time you connect. Right-click on the wireless icon at the bottom right part of your screen and choose View Available Wireless Networks [fig. 3].
