Note that the screenshots show the default theme - other themes can have different icons.

Note that if you use KDE rather than Gnome you will need to convert the certificate format following the instructions in steps 1 to 4 of the Unix section of Converting the root CA for use on mobile devices (the remaining steps are mobile device specific).

Configuration steps

Make sure that you have your credentials (eduroam identifier and Network access token (username and password)) from the UCS Tokens service.

All the settings you have made are stored in your computer and should not need re-entering each time you connect to the eduroam network.
