Internet connection at CERN
There is a wireless LAN connection inside restaurant 1 (building 500) where you can register your laptop and get access with your CERN login. You can also use the computers in front of the user office (you just need a CERN login) and you might be able to connect your laptop to the internet in your office .
Rules regarding what sites can be accessed by computers connected to the CERN network can be found at: https://security.web.cern.ch/security/rules/en/index.shtml
Some software applications are not generally permitted at CERN or its usage is restricted. If professional use is being considered please contact Computer.Security@cern.ch
In Buildings 38, 39 and 41 you can have access to wireless LAN with your CERN registration and login.
At the Hostel in Saint-Genis-Pouilly (French side) you have to go to the reception to ask for a special card giving an access code which allows you to access the internet. All of these services are available free of charge.
