WiFi: Configure Ubuntu Linux Device

Add the Security Certificate

The following instructions are provided for Ubuntu 9.10 and above. These steps may differ from other distributions of Linux. Consult the help documentation of your distribution for instructions on setting up a WPA2-Enterprise connection.

1. Aquire the Radius Certificate file.
2. Rename the file from a .txt file to a .crt file.
3. Save the .crt file to a location where it will not be deleted (e.g., ~/ or ~/Documents/). It will be needed for subsequent connections.

Some Linux distributions require the top level root Certificate Authority instead of the certificate that was used to sign the servers certificate. If the InCommon certificate above does not work, add the AddTrust External CA Root file.

1. Locate the Network Manager icon in the notification area. (It is a small signal strength indicator, and will be located near the clock.)
2. Right-click the Network Manager icon to verify that Enable Networking and Enable Wireless are selected in the drop-down list.
   
3. Click the Network Manager icon and select MWireless.
