Network access

If you have eduroam account provided by your home institute, you can use this network to gain connectivity.

If you don't have eduroam account please connect your device to the “CERN-Visitors” Wi-Fi network.

You should be redirected to the “CERN Visitor Wi-Fi” registration portal. If not (as this is device dependant), open a web browser and you will see the registration portal.

This portal provides registration-free access to a limited number of publicly available CERN websites. For full internet access, you need to agree with the CERN computing rules and register by providing your email address and a mobile phone number to which an access code will be sent by SMS. Once you have received and entered the access code, you will be able to access remote web sites (via http and https on standard tcp ports only) as well as some other authorised services such as e-mail, VPN and  SSH.

Note that the “CERN-Visitors” Wi-Fi network is not currently available in all buildings. If you cannot see this network you will need to ask a member of the CERN personnel to approve your access to the CERN Wi-Fi network as for the case below.

If you need a full access to internet (no restrictions on tcp/udp ports and applications), please see the use-case below.

  • connect to the Wi-Fi network named “CERN” and open a web browser. You will be redirected to the CERN registration portal where you will be guided step-by-step to register your device as a “guest”. As you do not have any CERN account, you will be asked for:
    • Your personal contact (name, email, etc…)

    • Visit detail (arrival/departure)

    • A CERN contact person. This person will receive an email and will have to approve the network connection for your device. Once this is done, your device will have full access to the CERN campus network and to the Internet.

As the “CERN” Wi-Fi network security mode is “open”, no specific settings are required (no WPA, no 802.1x options, etc…), but please note that this also means that the traffic you send over the Wi-Fi network is not encrypted. You should ensure that any sensitive data is encrypted at the application level (SSH, HTTPS, SSL, VPN, etc.). More information concerning computer security at CERN can be found at http://www.cern.ch/security/
