How Can I Connect to the Wireless Network of the University of Mannheim?

You can connect your mobile devices to fast and free broadband Internet everywhere on campus. Furthermore, students have access to special network resources provided by the institutions of the university, such as the online databases of the Mannheim University Library.

Hotspot information

Please turn off individual hotspots on campus. These hotspots diminish the bandwidth on campus and disrupt the entire network.

Another tip for a quick Internet connection on campus:
Turn off the Wireless of your device once you are seated and wait a minute. As soon as you enable the Wireless again, your device will connect to the next Access Point.
