eduroam mit Android
Notice when changing the password of your GWDG account:
If you change your password for your GWDG account after setting up the eduroam profile, the password must also be changed on your Android device. Otherwise the network connection cannot be established.
Setting up the eduroam WLAN with the CAT tool
1. The configuration wizard (CAT app) is required to ensure secure configuration. This can be obtained from the Google PlayStore. Please pay attention to the provider information “GÉANT Association”. Alternatively, you can download APK directly from DFN.
2. After you have installed the “eduroamCAT App”, open the app and select the eduroam profile for the University of Göttingen and GWDG. If your institute has set up its own profile file on the “GÉANT Association” page, use it.
3.1. If the location service is activated in your telephone and you are currently in Goettingen, the GWDG Goettingen should be displayed on the start page of the app under “Nearby Configs”. Alternatively, you can enter the GWDG Goettingen in the app on the start page via “Manual Search”. Please select GWDG Goettingen now. A summary of the configuration file will now appear. To install, press the “Install” button.
3.2. Another possibility is to download the profile file from the download page via a direct link here. After downloading via the button, select your institute from the “Organisation” menu. For eduroam users with a GWDG account, the organization is called GWDG Göttingen. Then use the button to select the desired Android version.
4. Confirm with “Yes” that you want to install the profile.
6. Finally, the device settings for the installed profile are displayed.
Manual eduroam configuration
Please use the CAT-App , Android can not be configured manually for optimal connection security.
These instructions show how to configure the Android OS release mobile device settings to establish eduroam connection manually. Only perform the manual configuration if it is not possible to configure an eduroam connection using CAT (Configuration Assistant Tool) . Various Android devices may slightly different screen layouts.
Please use the CAT tool, since eduroam can not be configured manually for optimal security on Android. Manual configuration should only be used in exceptional cases, since no secure certificate check can be established on Android devices manually.
Root certificate for Wi-Fi use
Watch your step! In order to establish a secure connection with eduroam, it is necessary to have the root certificate loaded and installed. Although the certificate is already included in Android, it is used by default only for VPN and applications, but not for Wi-Fi. For this purpose it must be reinstalled.
Follow the steps linked here to download and install the root certificate for wireless usage.
Note: The root certificate must be reinstalled after deleting a wireless profile that used the certificate.
Attention: If necessary, delete an existing eduroam Wi-Fi profile in order to properly configure the certificate verification. To delete or edit a Wi-Fi profile, tap and hold on the existing Wi-Fi profile and select the option to remove from the context menu.
Manual Configuration Guide
If you are in the reception area of the eduroam WLAN network, tap → Settings → Connections → Wi-Fi to select the eduroam network. To display the available networks, your Wi-Fi must be activated. In a new window, you will be prompted to enter the eduroam configuration parameters (see eduroam configuration table).
The screenshot for the network settings shows the login data for a GWDG account as an example. Please enter eduroam@ as “Anonymous identity” and then the REALM according to your institute. Use the table of the section Username. As “Identity” enter your username according to the table in the section Username. Once the correct information has been entered and confirmed, the connection to the eduroam Wi-Fi network is established permanently.
If you are out of range of the eduroam Wi-Fi network, you can set up eduroam manually via → Settings → Connections → Wi-Fi → Add network.
The eduroam configuration parameters (see eduroam configuration table) must now be entered in the window that opens.

Update the Wi-Fi password after changing the GWDG account password
Note: Update your WiFi password on your Android device after changing password for your account. If you have changed the password or entered an incorrect one, an “authentication problem” will occur. To do this, navigate to “eduroam” as described above. Tap and hold the saved network eduroam to delete or change connection settings. Select “Manage network settings”.
Storage of the Wi-Fi password
Android devices offer the backup of data at Google. This allows extensive personal data, including the WLAN password, to be stored unencrypted on Google servers. This function is activated by default in a Google account that has been set up.
According to the university's password policy, passwords may not be passed on to third parties. Therefore this option must not be activated when using the GWDG identifier for eduroam. You can deactivate this option in the Anroid settings.

As an alternative backup solution can be e.g. the App Helium may be used (check German article in “GWDG-Nachrichten” Helium Backup für Android ). The App Helium does not require system route and can backup data encrypted.
