How to connect your computer with Linux to the Wi-Fi network Eduroam

Do you already have an username and password? If not, read how to obtain it.

Connecting via NetworkManager

First of all, make sure that you have the certificate UTN-USERFirst-Hardware installed in your system (SHA1 fingerprint is 04:83:ED:33:99:AC:36:08:05:87:22:ED:BC:5E:46:00:E3:BE:F9:D7). Without this certificate the connection will probably fail! You can download it here (binary format .crt) or here (text format .pem).

Depending on your distribution, start NetworkManager, usually by clicking on appropriate icon in the panel. Then choose the eduroam network.


Fill in the parameters of connection:


  • Security: WPA & WPA2 Enterprise
  • Authentication: Protected EAP (PEAP)
  • CA certificate: UTN-USERFirst-Hardware
  • PEAP version: Version 0
  • Inner authentication: MSCHAPv2
  • Username: your username according to the Central Authentication Service (<personal number>
  • Password: according to the CAS

Finally click on the Save button.

Your computer will attempt to connect, showing a wizzy blue icon where the network icon was.


Your computer should now display a bubble that shows you have successfully connected to eduroam.

Note on certificates: RADIUS servers have their certificate issued by TERENA SSL CA (TCS). This certification authority has its certificate signed by globally accepted certification authority UTN-USERFirst-Hardware, whose certificate is installed in most of the operating systems and devices. On Linux, it is usually present in the directory /usr/share/ca-certificates/mozilla. If you do not have this certificate in your operating system, install it.

SHA1 fingerprint of this certificate is: 04:83:ED:33:99:AC:36:08:05:87:22:ED:BC:5E:46:00:E3:BE:F9:D7
