Configure your Ubuntu 8.10 and above Linux machine to use Wi-Fi Protected Access-Enterprise (WPA2-E) at UC San Diego.

The following instructions are for users who have already installed UC San Diego system tools. If you have a different version or package, refer to the ubuntu site for installation documentation.


  • You must have root privilege on your computer to successfully complete these steps.
  • Ubuntu 8.10 has not been shown to function successfully on encrypted wireless when using the Broadcom BCM43XX series cards found in some notebook computers.
