Well Ricc, I totally agree with you but we need to put username and password before connecting. When I configured Hauwei for the first time, it has taken a IP from BSNL DHCP, I have not given any IP address or DNS server while configuring the broadband. I dont have any static IP with me for this broadband connection. My router is having 4 rj45 ports and one of them is going to my systems NIC.

I have also gone through the GIU part but it's not giving me any option to put in username and password.

I will have a look at wvdial and will update you rock.

Need some more study on this router, I will be doing it in this weekend.
Thanks for your help guys!
