Changes for wireless access profiles at Leibniz University and TIB

From 9 July 2019 access only possible with new certificate and only via "eduroam"

At all TIB sites students and staff of Leibniz University Hannover (LUH) have been able to access the internet via the Wireless Local Area Network (WLAN) operated on campus by the university's IT services. This "LUHWPA" network will be deactivated on 9 July 2019. You should therefore change your access points to "eduroam" (Education Roaming) in good time beforehand in order to continue using the wireless network. This roaming service provides a network for internet access in the field of science: Via eduroam, you can use WLAN free of charge at all participating universities and research institutions worldwide after prior registration.

On 9 July 2019, the CA certificate will expire, which will be used, among other things, for the authentication of clients in the WLAN. For this reason, the registration profiles for the WLAN "eduroam" on all devices that use this WLAN must be changed by then. The easiest way to make the change is to use the so-called "eduroam CAT-Tool" (eduroam Configuration Assistant Tool) or - for smartphones - with the CAT app. Further information on the changeover can be found on the Leibniz Universität IT Services website at

From the beginning of June, an information page on the necessary profile changes will appear for all profiles that have not yet been converted immediately after logging into the WLANs "eduroam" or "LUHWPA". All eduroam profiles that have been set up with the CAT tool since October 2018 are already equipped with the new CA certificate and no longer need to be converted.
