Laptop registration

If you are a short-term visitor, and you are a registered user of Eduroam at your home institution, you should be able to connect without further ado. See CERN's "Eduroam for visitors" page for more information.

If you are here for a longer period, you can use any electronic device at CERN (and as many as you need), provided you have registered it. 

You can register your device(s) either before your arrival, or once you are at CERN. The procedure works both for ethernet and wireless connection

  • If you are already at CERN : if asked, select the CERN network (Please try to avoid to connect to the CERN Visitor network as this does not cover completely the area of our department). Open a web browser (Explorer, Firefox, Safari...) and you will be directed to the registration page (**). Fill in the sections marked with (*). If you do not have a CERN computer account, as 'CERN contact' please use the name of Gianolio Elena (TH department, GS group). If you wish to register both ethernet and wireless you can add both card numbers during the same registration. Once you have registered your computer you will need to restart it (***).
  • If you wish to register your device(s) before your arrival: go to the web page and follow the instructions given above.

For any question or problem do not hesitate to contact Elena Gianolio.
