To help keep the UCT network secure, each year, ICTS renews wireless authentication certificates for our wireless service – eduroam. While the process is seamless for some customers, this year, many users will need to take action.

Does this affect me?

Please note that you need to follow these steps only if:

  1. You will be connecting this device to eduroam (either at UCT or elsewhere, such as certain public libraries in Cape Town or participating eduroam institutions locally or abroad).
  2. You are using eduroam with one of the following operating systems:
    • Windows 10 or 11
    • macOS 10.x, 13 or 14
    • iOS 17
    • iPad OS 15 or 17

If you do not fall into these categories, you do not need to take any action.

What do I need to do?

  1. When you connect to eduroam on your device / computer, a pop-up will appear, asking that you trust the new certificate.
  2. Select the appropriate option to trust the new certificate.
    • Windows 10 or 11: Click Connect.
    • macOS 10.x, 13 or 14: Click Continue.
    • iOS 17: Tap Trust.
    • iPad OS 15 or 17: Tap Trust.
  3. You will be presented with a pop-up related to the server certificate
  4. You may now use your device / computer as normal.

After following these steps, if you still have issues connecting, please:

  1. Delete / forget your eduroam connection.
  2. Connect to eduroam again.
