General Information

Due to the large number of Android versions and manufacturer customizations, it is not possible to provide general instructions here. Individual settings may therefore differ from the instructions described here.

Mobile devices using the Android operating system will connect to eduroam without a specific certificate by default.

Configuration of eduroam

1. Open the WLAN settings under Settings → Wireless and network → WLAN settings and select eduroam.

2. Configure the connection with the following settings:

EAP method: PEAP

Phase 2 authentication: MSCHAPV2

CA Certificate: System certificate / default

Domain: radius.zdv.uni-mainz.de

Identity: username@uni-mainz.de
Username = username of your JGU account. Make sure that you really use your user name before the @ and not, for example, an email alias that differs from it!

Anonymous identity: leave blank

Password: Password of your JGU account

Click on Safe/Connect.

1. Click on the wireless symbol in the lower right of the task bar: 

2. All available networks will be shown. Choose the network eduroam and then click on Verbinden.

3. You will be asked to enter your login data.

Important: enter your user name as follows:

username@uni-mainz.de (users of other institutions participating in eduroam may use the equivalent login data of their institution, for example: mustermann@uni-frankfurt.de)

Passwort: your password for this institutional account.

Please make sure to enter your user name before the @ and not, for example your mail alias which may be different!

4. The message "Die Identität des Servers kann nicht überprüft werden" will be displayed. You may get the details of the certificate to be displayed.

From 2 March 2023, 11.00, you will find the following finger print in the details of the certificate:

53 ad 5c 66 ea ae f6 b8 9a 05 4c 37 60 18 6e 95 50 c6 22 6b

Then click on Verbinden, to estalbish the connection.

In case this does not work ...

... and you receive the message "Verbindung zum Netzwerk kann nicht hergestellt werden" then the required certificate is probably not installed on your computer. The solution: while you are connected to another network (Winulum, for example), visit any https page (for example: OWA → https://mail.uni-mainz.de, or JoguStINe → https://jogustine.uni-mainz.de) within Internet-Explorer (do not use chrome, Opera, Firefox ... for this, as these will not automatically do the following) - when you do this with Internet Explorer, the required certificate will be installed and will subsequently be availabe for all wireless connections using eduroam or uni-mainz.

Remove Winulum

If you wish to use an Applie iPod with eduroam you will have to delete any existing Winulum connection, because otherwise an eduroam connection cannot be established.

Below Einstellungen, Wi-Fi-Netzwerke, press the arrow to the right of winulum, then press Dieses Netzwerk ignorieren and confirm this again.

Configuring eduroam

Then press the Home button on your iPod/iPhone, and the button Einstellungen:

Press Wi-Fi (must not be connected), then choose the network eduroam:

You will be asked for your user name and password. Please enter your user name (JGU account name), followed by @uni-mainz.de and the corresponding password. After that press Verbinden in the lower right.

Make sure you enter your real user name - not, for example, your mail alias, which is different!

The wireless network eduroam is also offered at other universities. If you wish to use eduroam at other universities, when entering your JGU account data you will have to add @uni-mainz.de to your JGU account name (even though it looks similar: this is not your e-mail address). Without that addition, at another university you would be regarded as a local user - and because presumably no user with your combination of user name and password exists there, a connection would then be refused.

Using the certificate

We will now show you the certificate data. Check the certificate below Mehr Details.

The right certificate is issued for the server radius.zdv.uni-mainz.de and it contains the following information for verification purposes. some of which will be displayed here:

CN = radius.zdv.uni-mainz.de
O = Johannes Gutenberg-Universitaet Mainz
L = Mainz
S = Rheinland-Pfalz
C = DE

finger print: ae bc 5d d0 ee 25 02 d1 14 e5 8e 77 45 a4 64 b7 37 73 b9 69

If a certificate with this information is displayed, click on Annehmen. Now wait until a connection has been established. The next thing on display will be an overview of the Wi-Fi networks. Done.

Establishing the connection

Look for the network eduroam under Einstellungen → Netzwerke. Then click Verbinden.

Enter your user name (JGU account) in the form username@uni-mainz.de and your password. Then click OK.

In front of the @ symbol please enter your real user name, not, for example, your mail alias, which is different!

The following notification will then appear:

For displaying the details of the certificate click on Zertifikatsdetails anzeigen.
Something like the following will then appear:

From 9 July 2019, 18.00, you will find the following finger print in the details of the certificate:

Then click on: Verbinden.

In case this doesn't work ...

... and you receive the note 'Verbindung zum Netzwerk kann nicht hergestellt werden': this probably means that the necessary certicate is not installed on your device. To solve this problem, you may use another network (winulum, for example) and then open a https URL like OWA (→ https://mail.uni-mainz.de) or JoguStINe (→ https://jogustine.uni-mainz.de) with Internet-Explorer (not Chrome, Opera, Firefox or another browser, because it won't work there).
If you open that URL in Internet Explorer, the necessary certificate should be automatically installed and will then be availabe for wireless connections like eduroam and uni-mainz.

The University of Mainz takes part in the → eduroam network, in which universities have joined forces in Europe (in the meantime even worldwide).

Under the network name (SSID) eduroam, the center operates campus-wide data processing for an encrypted wireless LAN. WPA/WPA2 Enterprise with TKIP and AES encryption serve as security mechanisms. The coverage is consistent with the coverage for the wireless LAN uni-mainz (with the exception of the University Clinic areas).Members of other universities participating in the European eduroam network can connect to the eduroam wireless LAN via the University of Mainz, by logging in with the JGU account of their home university.
Conversely, members of the University of Mainz who are at other universities in the eduroam network may use eduroam with the Mainz JGU account.

Instructions for setting up eduroam with various operating systems can be found below and in the navigation bar.

When using the following instructions for configuring eduroam on various operating systems plese note:

Usually it should not be necessary to download a certificate any more. The certificate we use is already available on most devices.

Users who have already used eduroam with an older configuration (using the orca certificate that had to be separately installed) will have to delete their existing eduroam connection first and may then re-configure it.
