My laptop is running on Ubuntu 12.04.3 and using Tata Photon Plus dongle. I configured the device through the network manager options. It worked seamlessly.
Few days back I received message from Tata Photon that "we are upgrading our network for a better experience. Click ACTIVATE on your photon dialer settings & enter 0000 as PIN to enjoy uninterrupted serives".
Since then photon connection has stopped working though my laptop is detecting the dongle when it is plugged in but it can not establish the connection.
I am not able to find any solution. Any help would be really appreciated.
To further explain my problem, I have noticed that "Enable Mobile Broadband" option is checked though the "Mobile Broadband" icon is "not enabled". I notice these symbol on the tray.
