I have installed Ubuntu 12.04 few months back. My modem, Tata Photon Plus got connected after a number of unsuccessful trials and I browsed the net successfully.
But since a month, it is not getting connected. Whenever I try to connect, it shows this msg:
You are registered on the home device
Modem Network-Disconnected, you are offline
The network signals are completely ok as I am using the same device in Windows 7. I plug in the modem every time I try to connect it.
Please help me out.
