To establish a secure, encrypted Wi-Fi connection, digital certificates are used, which must be validated by certification authorities. These certification authorities are pre-installed on devices running Android 14 or later, and you can begin setup immediately; for older Android versions, you must first install the certification authorities manually (see below).

Settings > Network & Internet > Internet > Networks: eduroam

• EAP method: PEAP
• Phase 2 authentication: MS-CHAP v2
• CA certificate: Use system certificates
• Minimum TLS version: TLS v1.0
• Online certificate status: Do not check
• Domain: hs-woe.de (Note: This option is not available on all devices and can be ignored in that case)
• Identity: Domain login (Format: ma1150@hs-woe.de)
• Anonymous identity: <empty>
• Password: <Your password>
• Connect

In Android 13 or older, you must first manually install the certificate authorities (CA certificates) into the operating system.

• Download the two required certificate authorities to your Android device via a mobile data connection
  • HARICA TLS RSA Root CA 2021
  • GEANT TLS RSA 1

Depending on the device manufacturer, the installation of the certificate authorities varies slightly:

• Search for the term “CA certificate” in the settings
• Confirm any security warnings by indicating that you wish to install the certificate despite these warnings.
• Follow the instructions and select the two downloaded files one after the other (usually located in the Downloads folder)
  • harica_tls_rsa_root_ca_2021_20210219.pem (if a name is requested: HARICA TLS RSA Root CA 2021)
  • geant_tls_rsa_1_20250103.pem (if a name is requested: GEANT TLS RSA 1)

After installing the certificate authorities, you can begin the setup (above).

If you are unable to connect to the eduroam Wi-Fi network despite the settings above, please try the following:

• Tap and hold the eduroam network, then select “Remove Network”
• Restart the device and re-establish the connection as described above.
