Ubuntu 16.04 problems connecting to eduroam

Question

Using Ubuntu 16.04 and have been connected to my UNI's eduroam wifi fine till a week ago. Now it keeps asking for my password and wont connect.

Have tried workarounds from other similar questions asked but no joy.

Help!

Answer 1

I had a similar problem. I removed the old connection and set up a new one manually which worked for me.

To remove the old connection, I removed the file named "eduroam" in the directory "/etc/NetworkManager/system-connections".

You may set up Eduroam manually as follows: type "sudo nm-connection-editor" in terminal. Punch you password, if asked for. This opens the connection editor. Now fill in the details along with your credentials as you would have done for a usual setup. That is all.

If you want, you may use gedit or nano and create a new connection in the above mentioned repository.

I am not sure, but you might have to log out and log in again to get connected.

However, I do not know why this worked and the usual set up did not!

I followed the instructions linked here, in the GUI section. Everything worked fine on 16.04. Here's a copy of my resulting config file found in: etc/NetworkManager/system-conenctions/eduroam (my personal info has been replaced or blacked out).

Answer 3

At some point, probably after upgrading to Ubuntu 15 or 16, I became unable to connect to eduroam with my laptop.

After trying a lot of possible solutions, I found that all my problem was due to the nl80211 driver that was not working. Finally I could solve all my problems following an Arch Linux guide.

Although in my system I had to add the wext driver in /usr/share/dbus-1/system-services/fi.epitest.hostap.WPASupplicant.service. I simply included -Dnl80211,wext to the Exec line. So that the whole file is now:

[D-BUS Service]
Name=fi.epitest.hostap.WPASupplicant
Exec=/sbin/wpa_supplicant -u  -Dnl80211,wext  -O /run/wpa_supplicant
User=root
SystemdService=wpa_supplicant.service

With this I can connect to eduroam again!

As of 2023, there exists a configuration assistant tool available for all major OSes here https://cat.eduroam.org/. The tool itself is a python script that sets a connection and creates the necessary certificate.
