    New configuration of WiFi necessary ?

    You use eduroam? Have you already installed it via CAT?

    Then just set up eduroam again using the CAT tool.
    Delete the old eduroam and RZUWsec profiles beforehand (for instructions, see Delete profiles)

    Old configurations will not work after July 9, 2019 (certificate expires)

    Please use eduroam, which has been set up via the CAT tool.

    Since RZUWsec is now integrated in eduroam and will be off at the end of July, it will no longer be installed via the CAT tool.

    Use eduroam® CAT (Configuration Assistant Tool) for setting up eduroam. The installer will automatically configure access to eduroam and in addition WiFi RZUWsec on your device. You only need an active internet connection, e.g. via mobile network or @BayernWLAN and a user account of the university.
