[Update 19.06.2026] Changes to the Wi-Fi configuration as of 26 June 2026

During the night of 25 June to 26 June 2026, a mandatory change will be made to the university’s Wi-Fi configuration (HN1X/eduroam), which requires your cooperation.

Unless you update the settings on your Wi-Fi clients, you will no longer be able to use the HN1X or eduroam Wi-Fi networks from 26 June 2026 onwards.

We apologise for the short notice of this information.

During the annual renewal of the digital certificate we discovered that the PKI provider Telekom Trust-Center had changed the underlying certificate authority with effect from 21 May 2026 without prior notice.

You can carry out the necessary adjustments to the client-side Wi-Fi configuration yourself using the information, files and supporting configuration tools provided.

Thanks to an updated beta version of the iHN app (iHN beta), it is now possible to use the app to set up your Wi-Fi configuration for the first time on Android and iOS. This means you are well prepared for the switchover from 25 June to 26 June and can use the Wi-Fi without interruption, both now and after the switchover.

The iHN (beta) can be installed alongside an existing installation of the production version of the iHN app without any issues.

The updated instructions and required files are now available on the Moodle e-learning platform (German only) via the following links:

Wi-Fi eduroam

For all operating systems client-side adjustments can be carried out in full in the run-up to 26 June 2026, meaning that the certificate changeover from 25 to 26 June will be transparent to you, provided the necessary adjustments have been made.

Please also note the dates for the Zoom consultation sessions regarding the migration, which have been announced by email.
