Step 1: Installing the certificate

Make sure that the T-TeleSec GlobalRoot Class 2 certificate has been installed on your phone. You can check it by trying to choose the certificate for eduroam in the wifi-settings. 

If this is not the case, please connect to the RWTH-guests-network, start the browser and download this certificate (Certificate Chain of the DFN-PKI).


Please make sure that the certificates are downloaded only with the native or the Google Chrome browser. For all other browsers (Firefox, Opera, Dolphin, etc.) proper installation of the certificates is not guaranteed.

In addition, the purpose of the wireless network must be specified explicitly in some Android versions, otherwise the certificate at the eduroam device can not be selected. The certificate name can be chosen freely (in this example ‘T-TeleSec GlobalRoot’).

Be sure to enter the anonymous identity as described above. Otherwise you will not be able to connect to the eduroam WLAN after 09.07.2019.
