I was unlucky to have d link as my first modem..it troubled me so much I will never use it again..the only plus point it has is that its cost is less compared to other exrenal modems..but terrible..its not suited fro indian telephone line conditions which is susceptible to frequent disturbances..first thing it took me lot of time to get logged into net...once logged the connection is cut after some minutes..and I was forced to buy a new us robotics external modem which is superb
