Enable authentication on the wired network

When connecting to the wired network you might be asked to log in using your username and password.

Previously we asked you to turn this off, as it led to problems with the connection on your mac.

In the new network architecture at NTNU, it is necessary to turn this function on for the network connection to work correctly

This article explains how to turn this setting on.

Summary

  1. Make sure your network cable is plugged in
  2. Open System Settings from the Apple menu
  3. Go to Network
  4. In the right column, click on your wired network (not the Wi-Fi network)
    • The wired network has a green circle to the left
    • The Wi-Fi network may also have a green circle, but do not change the Wi-Fi network
  5. Click the Details button on the right
  6. Choose 802.1X on the left
  7. Enable the Enable automatic connection slider
  8. Click the OK button in the lower right corner
  9. And you're done! You may close the System Settings window
