My university eduroam work fine, but it was hard to make it work.
As say in a previous post you need wlan tool, check allow ttls/pap.

after same as said with a minor change in my case:


Application Launcher -> Settings -> Connections -> New

- Select "next"
- Connection name could be "Eduroam" but it freely choosable
- Select "next"
- SSID is the Network ID of your wifi network (should be "eduroam")
Network Mode is "infrastructure"
Authentication Method is "WPA with EAP"
- Select "next"
- EAP-Type is TTLS
- Select "next"
- Certificate is usually not needed, but you need to make sure your certificate chain is complete. So if your university uses for example Telekom Root certificate it is included in PR1.2. If not, you have to install it (Download, click on it via File Manager)
- EAP Method is "EAP PAP" (now available thanks to wlantool)
- Select "next"
- Username is ... actually your username given by your network admin, same goes for password
- Select "next"
- Select "advanced"
- Select tab "EAP"
- Check the upper checkbox there
- Enter your identity in the textfield below
(login@your-university.edu for example)
- Select "save"
- try it
