To use the University MÜnster' Wi-Fi a profile is required. Otherwise it is not possible to do the setup correctly. (Specifically, this is about the definition of the "external identity".)
If you have already used the network of Münster University, you have to delete the previous settings. Depending on whether you have set up the WLAN manually or via profile, follow the corresponding instructions for deleting.
Note: To download the profile, you can use our guest Wi-Fi GuestOnCampus.
Enter your university e-mail address (YourUniversity-ID@uni-muenster.de). Tap "Next". Note: Please note that email aliases, such as firstname.surname@uni-muenster.de will not work. The form YourUniversityID@uni-muenster.de is mandatory for the setup.
The certificate of the server radius06.uni-muenster.de for the WiFiconnection is renewed every few months for technical reasons. Thereby it will happen that you have to trust the certificate again as well. To do so, tap Trust in the upper right corner as shown in the screenshot.
