If you set up eduroam before 16 December 2023 you will need to reconnect by following the instructions below. Your existing eduroam connection will stop working on 31 January 2024 if you do not. It's the same process for existing users who are refreshing their eduroam connection and new users who are setting up eduroam for the first time.

Before you start


Step 1: Connect to UniOfCam-Guest wifi network temporarily

You need to be online while you set up eduroam. You should connect via UniOfCam-Guest or another local wifi network if your College doesn't offer UniOfCam-Guest. Or you could use a wired connection.


Step 2: Create a network access token

Create a network access token for your device. If you've connected to eduroam previously we still recommend that you create a new network access token.

You need to create a separate token for each of your devices and for each service. For example, if you want to connect to eduroam and the UIS VPN from both your laptop and phone, you need to create 4 tokens.

Use a meaningful username following the format It may be helpful to add the year if you've created network tokens previously. For example, You will need to use lower case.

Keep the window with the new network access token open as you will need this when you are asked to enter a username and password later. 

Create a new network access token on the Networks Access Token website


Step 3: Download the eduroam installer

  1. Visit eduroam's Configuration Assistant Tool website: Select "Click here to download your eduroam installer".

  3. Your device type will be detected and the Chrome OS installer download link should appear.

    Select 'Download your eduroam installer Chrome OS'.


    Download the Chrome OS eduroam installer button on the eduroam CAT


  4. The installer will then be downloaded to your device. Now open the Chrome browser and type, or copy and paste, "chrome://network#general" in the address bar.

  5. Select the 'Choose File' button under 'Import ONC file'.



  6. Select the .onc file you downloaded from the eduroam site - "eduroam-chromeos-UoC-eduroam_public_CA.onc"

  7. If prompted select EAP type as “PEAP” and Phase 2 Authentication as “MSCHAPV2”.

  8. You won't see any confirmation that the import has been successful, but the settings should have been updated.

    You should now be able to connect to eduroam by selecting 'Settings', then 'Wi-Fi', then choose eduroam.

  9. When asked for your username, enter the username of the network access token you created earlier. This should be in the format, for example,

    Enter the password for the network access token you created.


Step 4: Forget the UniOfCam-Guest network

Finally, forget the UniOfCam-Guest network or your local College wifi network, if used during the set-up steps. This ensures you will connect to eduroam wifi network whenever in range.

  1. Select 'Settings'.
  2. In the 'Network' section, select 'Wi-Fi'.
  3. Select 'Known networks'.
  4. Find 'UniOfCam-Guest', then select the 3 dots for more options. Select 'Forget'.
