internet-connection

I am trying to connect to Internet using Samsung corby Mate in Ubuntu 11.04 which shows using:

$ lsusb     
Bus 005 Device 005: ID 04e8:663f Samsung Electronics Co., Ltd SGH-E720/SGH-E840
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The mobile broadband creates a connection but doesnt connect to internet.

Mobile broadband fails to connect.

Somehow on Internet I found scripts to connect to Internet, but now only browser can access it, Ubuntu Software center does not recognize this connection and when try to install any software it doesnt display active internet connection.

I am using two chatscript & connection in /etc/ppp/peers & /etc/ppp respectively.
