Erratic connectivity problems with Eduroam on 14.04 - possible workarounds?

Question

I have to connect to eduroam through TU Delft settings from the following link

https://intranet.tudelft.nl/fileadmin/Files/medewerkersportal/ict/Help/Handleidingen/Medewerkers/Draadloos_netwerk/Eduroam/doc/Linux-wireless_eduroam1.0-EN.pdf

The connection problem is not one but many - sometimes I cannot connect to the wifi itself, most of the times I get connected but get no internet access, but magically in one of the buildings I was able to run everything like a charm.

The problem is that I can connect to most other wifi networks and on my windows boot everything is a charm.

Can anyone suggest any workarounds/ mends for this issue ?

EDIT: here's the status when the system was connected to the network:

See this for a password setting in the connection config file.
