Note

Please note that the following instructions describe how to set up the Eduroam network using the CAT configuration tool.


When prompted for user data, be case-sensitive and enter your username (not an alias) including @uni-bremen.de.

For security reasons, the WLAN password is not the same as the password of your Uni account. Students set the
Password automatically when activating the Uni-Account, other users have to set up the WLAN password once in the onlinetools.

If you prefer manual setup, you will find manual setup instructions further down this page.
