you need to give more details ...your operating system , modem numberhow is modem connected (USB / LAN)your network configuration (gateway , IP address ,DNS entries)ADSL Link Lamp should be constantly glowing . It indicates that connection from Exchange is okay .the best suggestion could be to contact Local BSNL as it is a new connection .
