My modem failed last week(frequent drops), and I was not willing to repair this time. I’ve taken a screenshots of configuration from my old modem, with the help I was able to configure my new D-Link 2750u.

If you would like to keep tabs on your bandwidth usage?

It is good to know your usage, the 10GB fair usage plan from Airtel is peanut for my usage as I download a lot of TED & iOS Dev videos from iTunes.
