Using a ADSL WIFI Modem+ Router only as a router

[Akash Dajied Kharkongor]

Hello, I am using a D-Link 2750u Modem+Rtr, and my ISP has already provided me with a modem that receives a Co-Ax input and we get the internet via Ethernet. this Ethernet i have connecte dto our D-Link. I have configured the Router. But i can't seem able to get internet access. The Ethernet from the Modem has been connected to the LAN port of the D-Link.

Unfortunately, this is unlikely to be possible. You need a router with an Ethernet WAN port.
