eduroam (Wi-Fi)

The HfG Karlsruhe is part of the eduroam federation, which is used to connect to Wi-Fi. Once set up, HfG members can connect to Wi-Fi at other institutions which are part of eduroam. Conversely, HfG's eduroam Wi-Fi is open to members of other participating institutions.

Connect to the eduroam network primarily, and use eduroam-hfg only when you are incidentally being connected to the eduroam network of the neighbouring ZKM.

To connect to Wi-Fi at the HfG Karlsruhe, you need to configure the eduroam or eduroam-hfg networks.
