Setting up eduroam: Android (manual configuration)

How to manually configure eduroam on an Android device

We recommend that you manually configure eduroam on an Android device only if you're unable to use the eduroam CAT

Manually configuring eduroam on Android devices can be complicated and prone to error because of the variations between different versions of Android. Our new 'eduroam CAT' app simplifies this process, and we recommend using it wherever possible. However, if for some reason this process fails, then you can follow the manual instructions below.

Before you begin, make sure:

  • you're in a location where the eduroam wireless network is available
  • you have created a network access token for this device on the UIS token page.

These instructions were written using a OnePlus 5T running Android 8.

 

1

Download and install the University of Cambridge CA Root certificate.

  • Before you start, remove any current configuration for eduroam. Go to Settings then Wi-Fi. Press and hold on eduroam. If the option to Forget network or similar appears, then select it and continue. If the option to 'Forget network' does not appear you can still continue.
  • Make sure you are connected to the internet (for example, via a mobile network or by connecting to the University's UniOfCam Wi-Fi network.
  • Download the University of Cambridge Wireless Service Root CA.
  • Your device will ask you if you want to download the certificate (wireless-ca.crt). Choose 'Download'.
  • At this point, differences in Android versions may become apparent. The next prompt will ask you how you want to open the certificate file. Select Open with Certificate Installer (or your preferred app).

  • You will then be prompted to Name the certificate and identify how it should be used. In the Certificate name field type "University of Cambridge Wireless Root CA" and choose Wi-Fi from the dropdown list for Credential use.

  • If at this point the certificate import fails, you can complete the process manually. Go to SettingsSecurity & lock screenCredential storage and select Install from storage (or equivalent menu options). From your Downloads folder, select the wireless-ca.crt certificate file. Complete the installation steps as instructed.

  • If at this stage you receive an error saying that a Screen lock is required then you will need to set one (even if only temporarily while completing this process) - go to Settings -> Security -> Screen lock (or similar) and set a PIN, Pattern or other Screen lock authentication mode. Once this is done the app should successfully complete the installation of the certificate (you will be prompted for the new Screen lock authentication details).

Once you have installed the certificate, configure eduroam with secure settings.

  • Open your Settings dialogue.
  • Select Wi-Fi.
  • Select eduroam.
  • A settings dialogue box should appear. Select the CA certificate list. The newly installed "University of Cambridge Wireless Root CA" should appear. Select it.
  • Complete the other options as described below:

 

  • Phase-2 Authentication is "MSCHAPV2".
  • Note that your username (identity) is the username of the network access token you created on the UIS token page for this device in the format CRSid+device@cam.ac.uk – for example, abc123+myphone@cam.ac.uk.
  • The Anonymous identity is "_token@cam.ac.uk".
  • The Password is the password for the network access token you created for this device.
  • Select Connect.

Your device should now connect to eduroam. Your password will be saved.
