Here is what Renkon said, I don't see his post here:

Eduroam works.

- You need PR1.2 and root access
- get the PAP GUI (https://bugs.maemo.org/attachment.cg...34&action=view)
- install .deb file from link above via a root (!!) prompt with:
dpkg -i wlantool_0.0.4_armel.deb

- now you will have the wlantool in your application launcher
- start it
- check the checkbox "Allow TTLS/PAP" and close wlantool
- now setup manually a new wifi connection with
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" (I'm on german maemo, it may be called "more" or something like that)
- Select tab "EAP"
- Check the upper checkbox there
- Enter your outer anonymous identity in the textfield below
(anonymous@your-university.edu for example)
- Select "save"
- try it

Sorry if any descriptors are not exactly right. As I said, I'm on german maemo and translating this on the fly
