Connecting to GTwifi on Ubuntu Linux

This example assumes that you have either a notebook or desktop with wireless capabilities running Ubuntu Linux 12.10 or higher.

If you cannot get your system connected, you can visit the OIT Technology Support Center on the first floor of the GT Library.

Notice for all Ubuntu users: We have found issues with attempting to use the default Network Manager package to connect to GTwifi. Some users experience frequent disconnects after configuring your machine using the default Network Manager. One solution that has been successful is to replace the default Network Manager package with WICD. Instructions for this can be found on the Ubuntu Troubleshooting Guide.

  1. Left-click the wireless Network Manager icon in the application panel at the top of your screen.

  2. Select GTwifi from the list that pops up. If GTwifi is not on the list, hover over "More networks" at the bottom of the list, and select GTwifi from the extended list that pops up.

  3. A box will pop up titled "Wireless Network Authentication Required".
    1. Leave "Wireless security" set to WPA & WPA2 Enterprise.
    2. Change Authentication to Protected EAP (PEAP).
    3. Leave Anonymous identity blank.
    4. Click the folder icon next to CA certificate.

  4. In the File Browser window that pops up, left-click on File System at the left
    1. Browse to "/etc/ssl/certs".
    2. Scroll down and select the file named "AddTrust_External_Root.pem".
    3. Click the Open button in the lower right-hand corner of the File Browser.

  5. Now that you're back at the Authentication Required box, ensure that PEAP version is set to Automatic and Inner authentication is set to MSCHAPv2.
  6. In the two boxes labeled Username and Password, enter your GT Active Directory username and password.
  7. Finally, in the lower right-hand corner of the box, click Connect.

  8. The wireless icon in the Application Panel should flash for a few seconds, and then a pop-up message should confirm that you are connected to GTwifi.

If you experience issues, an Ubuntu Troubleshooting Guide is available.
