How to connect to Cloudessa RADIUS using WPA2-Enterprise with Windows XP


Configuring WPA2 for Windows XP

Requirements for wireless using WPA2 on Windows XP with Service Pack 2

  • – Your wireless card must support 802.1x, AES, and WPA2.
  • – Windows XP with service pack 2, it is recommended to install all the latest updates (you can download them through the Windows update site http://windowsupdate.microsoft.com ).
  • – Make sure you have the most current drivers for your wireless card.

**Important first step: Windows XP users with service pack 2 must install a Microsoft update to enable WPA2 support before continuing. You will need to restart your computer after downloading
and installing the update. The update can be downloaded at http://support.microsoft.com/kb/893357.

Windows XP users with Service Pack 3 installed may continue with their configuration. Service Pack 3 has WPA2 support by default.

Service Pack 2 users, after installing the update and rebooting, you are then ready to resume the WPA2 configuration.

At the Start Menu select “Run” and type in “ncpa.cpl” and click OK.

This will take you to the network connection screen (Figure 1).

If WPA2 is not listed as an option, then one of the following is the likely cause:

  • – You haven’t installed the update from Microsoft as directed above (for Service Pack 2 users).
  • – The driver for your wireless adapter does not support WPA2. Check with the manufacturer to see if there is an updated version of the driver available.
  • – Your wireless adapter does not support WPA2.
