I am using dlink modem of model DWM-156 as an HSUPA USB adapter with a BSNL network sim in it. I am using Ubuntu 12.04 alongside with windows7. I have defined the network settings in the mobile broadband category. I can connect to the internet on windows7 but while using ubuntu I cannot connect to internet. Upon typing
in the terminal, I found that the dlink device is detected by Ubuntu.
What should I do to get myself connected to the internet?
