The University of Tübingen is represented on the website of the eduroam Configuration Assistant Tools (CAT). There you will find automatically generated eduroam installation and configuration files for many of the common systems. The files are automatically generated on the basis of the stored eduroam WLAN radius parameters of the University of Tübingen without any further influence by the ZDV. The ZDV has no influence on the function of the scripts / configurations or on the selection of the supported end systems.

Platform-specific installation instructions

Instructions for the configuration of Windows, Android, macOS, iPadOS and iOS can be found in the ZDV Wiki.


In the Windows version of CAT, the domain is added automatically. In all other CAT versions, <YourLoginID>@uni-tuebingen.de should be entered as the user name.

Manual configuration
