My Ubuntu 13.04 didn’t connect to the “eduroam”(“wwu”) wifi. It tried to auto-configurate the connection as android, ios, firefoxos, windows and mac do pretty well, but ubuntu failed.
First you have to download a certificate which should provide your university. I had to choose between three different certificates, i downloaded them all and tried them one after another. Problem here: My Firefox showed up that all these certificates were already installed by clicking on them, so i had to use the link below which showed me the certificate as a text in the browser. I opened a text editor, copy and paste, and I saved it as “filename.pem”. Unfortunaly my ubuntu is in german but anyhow you can see my configuration easily in the screenshot below.
