What is eduroam?
eduroam (education roaming) is the secure, world-wide roaming access service developed for the international research and education community.
eduroam allows students, researchers and staff from participating institutions to obtain Internet connectivity across campus and when visiting other participating institutions by simply opening their laptop.
Having started in Europe, eduroam has gained momentum throughout the research and education community world wide. Currently there are four regional eduroam confederations (for a detailed view of the countries that belong to each confederation, select the regional confederation above):
- in Europe (http://www.eduroam.org/?p=europe)
- in the Asia-Pacific ( http://www.eduroam.edu.au/eduroam-in-asia-pacific.html)
European eduroam server coverage
The map below depicts the European countries that have connected their national top-level RADIUS servers to the European top-level RADIUS server (ETLR).

In Italy the Italian Eduroam Federation is managed by GARR Consortium (http://www.garr.it) and includes more than 70 organizations/universities. You can check the updated list of federated organizations here: http://www.servizi.garr.it/index.php/it/eduroam/elenco-istituti-aderenti1
SISSA and eduroam
Since SISSA is member of the Italian Eduroam Federation, guest users that belong to federated institution can connect to SISSA network using their own credential (username and password). Also SISSA users, when visiting other federated institutions, can connect to the hosting network using their own credentials.
When visiting other federated institutions, SISSA's users can connect the hosting network using the wireless id eduroam and using their own SISSA credentials (username and password).
Be careful to always add the realm @sissa.it when entering your username.
For example: if your username is bianchi always insert firstname.lastname@example.org
The configuration of your computer is the same you use for WiFi connection in the SISSA buildings, except you have to use eduroam ssid and you must take care to always set your real username (with the realm @sissa.it) as the outer identity.
Eduroam Guest Users at SISSA
Guests users that belong to a federated institution can connect to SISSA network associating to the eduroam wireless id, and using their own credentials. Again remember to always add your institution realm after your the username, in the form email@example.com
For example: if your username is white and your institution top-level domain is cam.ac.uk (the university of Cambridge in this example) always login using firstname.lastname@example.org
Please note: eduroam guest users cannot access to SISSA printing services and to SISSA workstation, but they can access also SISSA wired network.
As a golden rule, you need to configure your device only exactly once, as instructed to by your home institution. From then on, you can use all eduroam hotspots world-wide without reconfiguring anything.
Exactly how to configure your laptop or other handheld device for eduroam will depend on
- which device(s) you are using and
- your institution's local identity management configuration
If you know that your school / university / college does provide eduroam, please ask the IT staff for support with setting it up on your laptop or other devices.
Important: the configuration instructions are specific for your institution.
It is not helpful to follow configuration instructions of other institutions; the settings are different from institution to institution and you will very likely misconfigure your device if trying third-party configurations.
If you are not sure whether or not your institution provides eduroam, the National Roaming Operator for your country may be able to help with your enquiry.
