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

We provide you with encrypted wireless access via eduroam. This way, you can connect your mobile devices to fast and free broadband internet everywhere on campus.  Furthermore, students connected to the university’s wireless network have access to special network resources provided by the university’s institutions, such as the online databases of the Mannheim University Library.

Please turn off any personal hotspots on your smartphone. These hotspots have a considerable impact on the channel bandwidth and disrupt the entire network.

Another tip for a quick internet connection on campus:
Turn off the wireless on your device once you are seated and wait a moment. As soon as you enable the wireless again, your device will connect to the next access point.
