Connect to the IU wireless network in Ubuntu

eduroam is replacing IU Secure as the default wireless network for students, faculty, staff, and affiliates on all IU campuses. As of May 26, 2021, IU Secure is no longer available in the residence halls, and will fully retire in the near future. All new wireless connections should use eduroam; see Connect to eduroam.

The simplest and most secure way to connect to eduroam is to use the Eduroam Network Setup Tool. Alternatively, you can use the instructions below to connect manually.

To connect to eduroam or IU Secure:

  1. Click the NetworkManager applet (a pair of superimposed monitors, typically in the upper bar on the right), and then select the network name (either eduroam or IU Secure). The "Wireless Network Authentication Required" window will appear.
  2. Configure the settings as follows:
    • Next to "Wireless Security:", select WPA & WPA2 Enterprise.
    • Next to "Authentication:", select Protected EAP (PEAP).
    • Leave the "Anonymous Identity:" field blank.
    • Click the button next to "CA Certificate:", and then browse to the certificate bundle file (/etc/ssl/certs/ca-certificates.crt).
    • Next to "PEAP Version:", choose Automatic.
    • Make sure "Inner Authentication:" is set to MSCHAPv2.
    • Next to "User Name:" enter your primary IU email address if you are using eduroam, or your IU username if you are using IU Secure. Next to "Password:", enter your IU passphrase.

      Do not check Show password, as it will display your passphrase in clear text.

  3. Click Connect. If the connection fails, you will be prompted to re-enter configuration details.
  4. Click Connect. If the USERTrust certificate is not present, check No CA certificate is required.

When you successfully connect, you'll see a series of blue bars of increasing height in place of the superimposed monitors.

If you continually fail to connect, try entering your username in both the "Anonymous Identity" and "User Name" fields. UITS has verified that this step produces a working configuration, and it has been shown to solve failures to connect.
