eduroam is a federated identity management system to allow members of participating institutions to visit each others site and use their WLAN network without further organizational or technical requirements. For more information about eduroam, lists of member organizations, FAQs and more see or

Login Information

For authentication use as login (WITH the domain appended; this is NOT your email address), your CampusNet password as password.

If you have the option, configure as username for OUTER authentication.

(info) eduroam gives you "network access". It does NOT give you "access to everything you need right now". Some Jacobs services are protected and not accessible from "the Internet", e.g. the JACOBS network home drive. In those cases, you still need VPN Access on top of eduroam connect.

(info) What "network access" means in detail is determined by the institution you are currently connected at! While Jacobs University is very liberal in offering Internet access, other institutions potentially aren't. "plain web" access via port 80 (aka HTTP) and mostly port 443 (HTTPS) is usually the minimum, but other ports like 8443 (HTTPS to tomcat, e.g. teamwork) or VPN connection might be blocked by the remote institution! If some services work for you, and others don't, please contact the IT staff at the institution you are currently at and figure out their institution's eduroam Internet access policy.

The following pages give configuration information for several device types. If you are looking for configuration information of another device.

As a shortcut to downloading the installer please visit the DFN eduroam CAT page.


  1. Dear IT-Team,

    thanks for the eduroam access and the great Howtos!

    If I went to any other institution also providing eduroam, could I simply log in without any configuration? I am asking because of the Telekom Certificate. Is it used anywhere else in the world, too? Or does any eduroam server recognize my usersame and password and "forwards" the authentication request to Jacobs?

    1. I think I found the answer myself at Wikipedia:

      Eduroam requires participating RADIUS servers to support realms. Within a single institution a user would usually simply be represented by a username and corresponding password for theirauthentication. By contrast a visitor using eduroam requires a representation of their home institution as 'username@realm', where the 'realm' is usually closely related to the visitor's home DNS name.

      The role of the RADIUS hierarchy is to forward a user's credentials to their home institution for authentication. The RADIUS server at a participating institution recognises the '@realm' component and proxies anything non-local to its national top-level RADIUS (NTLR) service, which is normally operated by the National Research and Education Network (NREN) of that country and which has a complete list of the participating eduroam institutions in that country.

  2. I finally got it to work on Linux (Fedora 18 for me).  The key problem was that Network Manager, for no good reason, does not like the .crt ending on the certificate file name.  Simply renaming the certificate file to end in .pem does the trick.

    Anyway, here is what you have to do in steps.

    1. Download the Telecom certificate: Use right click - Save Link As on this link
    2. In the download directory: "mv rootcert.crt deutsche-telekom-root-ca-2.pem" or use file manager to rename file.
    3. Add wireless network "eduroam" as described for other operating systems, where you point the certificate file selector to the newly renamed file deutsche-telekom-root-ca-2.pem.  Parameters in short:

      Security:WPA & WPA2 Enterprise
      Authentication:Protected EAP (PEAP)
      CA certificate:deutsche-telekom-root-ca-2.pem
      PEAP version:Automatic
      Inner authentication:MSCHAPv2
  3. Anybody who is successful in using eduroam with surface rt tablet? I installed the certificates via IE (local and user) but network access is still not possible. Actually (having this done once)  I am not asked for login information thus I cannot correct them if they were incorrect. Jacobs WLAN works.

  4. How about Windows 8 Pro - Do you have some hints how to install eduroam there? Thx, h

    1. Thanks for the reminder! Give this a try, with Jacobs data. It looks mostly the same as on Windows 7.

  5. Would it be possible to have our data added to

    One place to look, for (nearly) every OS (Windows Vista, 7, 8, 8.1, 10, Linux, Android 4.3+, MacOS, and Apple IOS Devices).
    download for mobile devices per QR code and it is
    also available in a lot of different Languages:  Български, Català, Čeština, Deutsch, Ελληνικά, English(GB), Español, Français, Galego, Hrvatski, Italiano, Magyar, Norsk, Polski, Português, Slovenčina, Slovenščina, Srpski and Suomi


  6. Any instruction for Windows 10?

  7. Sonia, just connect to the eduroam wlan hotspot and login with your and password. Not the email address, without dot!!
