11.10 Modem Disconnected, You are offline Now.

Yesterday i upgraded my ubuntu 11.04 to 11.10.
Everything gone great but after restart, my modem was not able to connect
with the system.
Error was "Modem Disconnected, you are offline now."
I resolved this issue with following steps

1. Click on Network Icon
2. Click on edit connection > Mobile broadband >
   select the network(tata photon in my case)
3. Go to  Edit then again click  on mobile broadband
4. Then Fill data like : 
            Number =#777
	    Username = internet
	    Password = internet.
5. Save it. Then it was automatically connected.
