Set up eduroam with the geteduroam app

The geteduroam app helps you set up eduroam on your smartphone, tablet or laptop quickly and securely. The app automatically applies the correct Wi-Fi settings for TU Braunschweig and ensures that your device connects to eduroam using a properly configured profile. It also enables secure validation of the authentication server’s certificate.
Note: If you experience problems with eduroam on iOS, it may help to remove the profile and Wi-Fi settings and then set up eduroam again.
Error message: Connection failed – cannot modify system configuration
Solution: Go to iOS Settings ➞ General ➞ VPN & Device Management. There you can remove existing eduroam profiles and then set up eduroam again using geteduroam.
Current information: The Wi-Fi profile was updated on 3 August 2026.
Since 3 August 2026, the eduroam profile provided through geteduroam has included the new DFN eduroam CA in addition to the existing Deutsche Telekom certificate chain. This prepares devices in advance for the upcoming change to the certificate used for eduroam authentication and helps ensure a smooth transition without interruptions.
Keep the configuration on your device up to date to prevent connection problems in the future.
Reinstall the profile to obtain the latest settings.
