The WLAN eduroam
The eduroam WLAN is a guest WLAN that can be used by DESY employees as well as by users of other research institutes. DESY employees can log on to the WLAN with their DESY account, while users of other institutes use their account of their home institute.
This means not only that people from other institutes can log on to the eduroam WLAN at DESY, but also that DESY employees can connect to eduroam with their device at other institutes after the setup, provided that the respective institute offers eduroam as WLAN network.
Preliminaries
To establish a connection via eduroam with a DESY account, you need a corresponding activation (resource "eduroam"). This can be done by the group administration responsible for you or by the IT helpdesk (e-mail: uco@desy.de, Tel: 5005), stating your account name.
Shortly after the activation, you will receive a message asking you to set your WLAN password in the DESY Registry. If necessary, please find instructions about that topic on this website.
How do I connect my device to the eduroam WLAN?
The login to the Eduroam network is done via the app application "Easyroam". It is therefore no longer necessary to download and configure WLAN profiles yourself, as these are generated and installed via the Easyroam app. This makes it easier to connect to the eduroam network. On this website you will find the instructions for the most common operating systems.
Instructions in english for all devices will be added soon here! For instructions on configuring eduroam on your device please see German version of this website for the time being (https://it.desy.de/dienste/netzwerke/wlan_am_desy/eduroam/)
Please note: During the configuration of eduroam you need an internet connection via another network. The following networks can be used for this purpose:
- Science Hotspot
- mobile network
- wired network
iPhone / iPad
|
1. Please make sure that you are connected to the internet. For this you can use another WLAN, for example the Science Hotspot in Hamburg, DESY guest or DESY guest legacy in Zeuthen, or your mobile data. 2. Important: Existing eduroam profiles have to be deleted beforehand. This action is needed if you already have an eduroam profile on your device. A connection without a profile was possible. To delete a profile follow these steps:

Windows
|
1. Make sure that there is a connection to the internal DESY network. Preferably use the wired network for this, alternatively a connection to the DESY WLAN or to the guest WLAN "Science Hotspot" in Hamburg, "DESY guest" or "DESY guest legacy" in Zeuthen in connection with VPN is also possible. Existing eduroam WLAN profiles do not need to be removed manually on Windows, as this step is performed by the Easyroam app. 2. Normally, the installation of Easyroam on DESY-Windows laptops should be executed automatically via DSM Software-Shop as soon as you have logged in to the device. The message appears as shown in Figure 1. Please confirm it via click on Ok. |
Figure 1
|
If you are not offered the installation of the package automatically, start the installation of Easyroam manually from the DSM Software Shop by installing the package "easyroam_Umstellung_eduroam". 3. Then open Easyroam from the Windows Start menu. This opens a web page. Here, search for "DESY" in the selection of available institutes and select it (Figure 2). |

Linux
|
Since DESY does not provide any Linux work computers, there is only limited support for WiFi on Linux laptops. However, setting up eduroam using the Easyroam app is possible on Linux devices. Instructions on that from the DFN can be found on the following website: https://doku.tid.dfn.de/en:eduroam:easyroam#installation_der_easyroam_profile_auf_linux_geraeten |
FAQ
What is the maximum number of devices that can be set up with Easyroam?
|
With Easyroam, no more than five devices can be set up to connect to eduroam at the same time. We have no influence on this maximum number, as it was set by the DFN. If you have devices on which you no longer need eduroam, you should therefore revoke the connection profile for the respective device in the Easyroam app. This is also possible from other devices on which you have installed and set up Easyroam. |
What can I do if I have connection problems?
|
If you experience connection problems, it may help to reinstall the profile via the Easyroam app. For this purpose, the "Reinstall" option is available via the Easyroam app in the administration of the respective profile. If this does not help, please check whether setting up the connection profile again via the "Request new" button will remedy the situation instead. On operating systems where the Easyroam app is not available, this simple option is not available. In these cases, the only way to set up a new profile is to set up the connection profile again, including deleting it beforehand. If these steps do not help either and you are using a smartphone, please proceed as follows:
If these steps do not resolve the situation, please contact the central IT helpdesk (e-mail: uco@desy.de, tel: 5005), stating your account name, the device model and the operating system version used. |
Which devices can be supported by the IT Helpdesk?
For devices that do not have a current operating system version and therefore no longer receive operating system updates, the IT helpdesk can provide no or only very limited support. If the usual procedures for solving problems do not help, a new device should be procured in the foreseeable future. At the time Easyroam was introduced (06/2023), in particular Android devices running operating system version 10 or older experienced an increasing number of problems that could not be solved or could only be solved with an extremely high expenditure of time.
General Information
|
Please note that by using Easyroam with your DESY account login you are limited to setting up up to five WLAN devices for eduroam. |
