The primary essid eduroam is available on the CESNET's premises for visitors from organizations connected to the eduroam project. If your device has a trouble with connection you can try to use non-broadcasted essid eduroam-wpa. Both essids are authenticated via 802.1x protocol.

You need valid user credentials for successful login to the eduroam network. You should obtain these credentials as well as documentation for client device configuration and user support at your home organization. Connected organizations are listed on eduroam.cz
