Wireless LAN is available almost everywhere on the FU campus. FU members and members of institutions that participate in eduroam can login to the campus network via eduroam.

Freie Universität Berlin participates in the eduroam initiative. This means that members of Freie Universität Berlin can also connect to the eduroam Wi-Fi at other institutions participating in the eduroam initiative without any additional configuration and using their FU account.
