I am a visitor and I only need access to Internet and CERN public resources. How can I get Wi-Fi access?
For this use-case, 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.
If you need a full access to internet (no restrictions on tcp/udp ports and applications), please see the use-case below.
I do not have a CERN account but need to access CERN internal resources and/or full internet access. How do I connect to the CERN Wi-Fi Network?
You may be concerned if you are for instance a conference attendee, or an employee of a company having a contract with CERN. In this case, there are two ways for you to connect to the CERN network:
- If you are an eduroam user, simply connect to the “eduroam” Wi-Fi network. Please see “Is eduroam available at CERN” for more details
- If you are not an eduroam user, 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/
I work at CERN and I have a CERN account. How do I connect to the CERN Wi-Fi Network?
The easiest way to connect your mobile device (Laptop, tablet, smartphone, etc…) to the CERN wireless network is to:
- activate Wi-Fi on your device
- connect to the Wi-Fi network named “CERN”
Once your device is connected to this Wi-Fi network, open a web browser and you will be redirected to the CERN registration portal. You will then be guided step-by-step to register your device using your CERN account and, after a short while, you will be granted access to the CERN network.

If you wish to have an encrypted Wi-Fi connection, you can connect using eduroam (please read the instructions here).
