  • Login is done using a username in the form of an e-mail address username@cvut.cz.
  • You can log in wherever the Eduroam network broadcasts (coverage in CZ) or (coverage worldwide).
  • Probably the best way to set up a client device is to use a configuration script. On the page eduroam CAT you can download the script for your operating system after you select CTU as your home organization. For manual configuration, the necessary informations are available on the page Wireless networks on CTU.
  • For devices with a newer version of Android OS (typically v10 and higher) works better the app "geteduroam".

Access to the faculty network from outside

Access to the faculty network from outside


Access to the faculty network from the outside is possible using a VPN service.

A VPN (virtual private network) is a tool to securely connect two computers via an unsecured network (in our case, usually the user's personal computer to the FJFI server via the Internet).
It can be used, for example, to access faculty servers or, if necessary, to run applications where the license is tied to the internal school network.

Employees (including postgraduate students in employment) may use CTU VPN service.

Students (teachers and staff too) can use, FJFI VPN service.
