In my previous blog entry I posted the settings for connecting to the eduroam network at the University of Groningen. Since yesterday however the security standard and the authentication method of the wireless network have been updated. To continue being able to access the eduroam network using your Nokia 5800 (and similar models) the settings as shown in the screenshots must be entered.
Make sure you delete any settings for the RuG-FN2 network which has been merged into the eduroam network. Also replace any username/password settings with your own.
Thanks to Willem Koster for figuring out these settings.
