I would suggest people having this bug to open new bug reports with as much details of their systems as they can provide. If the issue are really duplicates of this one, the new bug reports can be duplicated to this one later. I'm connecting with Eduroam networks with 3 different laptops (two with Ubuntu 14.04 and one with Ubuntu 15.10) with no issues, so I think people being hit by this bug are being affected by a combination of software and own hardware particularities.
