The guide my university supplied did not work after all with Linux. So I used an alternative guide, which also turned out to be working for Android:
Security: WPA2 Enterprise
Authentification Tunneled TLS (TTLS)
Anonymous Identity: none
Inner Authentification: MSCHAP2
User: firstname.lastname@example.org (as in the Windows settings guide of your home university)
password: your password, as in windows.
