WirelessLAN (eduroam, RWTH-guests)
RADIUS certificate change
On September 9, 2025, we will switch the RADIUS server certificate in the eduroam and RWTH-institutes networks to the DFN Community Root CA 2022 certificate.
In order for a device to connect successfully to the Wi-Fi, it must recognize the stored root certificate as trustworthy.
To avoid connection interruptions, we recommend to use the current eduroam CAT App or to install the root certificate manually.
Devices that have installed or updated the eduroam CAT App for Wi-Fi configuration after June 12, 2025 and devices with the EAP-PWD authentication method (mainly available on Android and Linux systems) are not affected by the certificate change.
For configuration instructions, see IT Center Help:
