WiFi: Configure Ubuntu Linux Device

Add the Security Certificate

The following instructions are provided for Ubuntu. 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, and see the Unsupported Devices page for additional details.

  1. Acquire the InCommon certificate file.
  2. Save the certificate 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 CA certificate instead of, or in addition to, the intermediate CA certificate that was used to sign the RADIUS server certificate. In this case, visit Comodo to obtain the root CA certificate.

Install MWireless

  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.

Troubleshooting Tips

  • It may be necessary to turn your wireless connection off and back on in order to connect the first time.
  • Make sure you have installed all available driver updates and patches for your Linux installation and your wireless device (check the wireless card manufacturer's web site for the most current driver updates).
  • Ensure that your computer is configured to connect to the wireless network automatically:
    1. Right-click Network Manager, and select Edit Connections.
    2. Click the Wireless tab, select the connection you configured, and click Edit .
