How to connect two routers with one BSNL Broadband Connection

BSNL is one of the largest Broadband service provider in India. It is a government owned company which basically provide mobile and landline facilities across India. BSNL is popular for its cheap 3G data rates but they don’t have 2G data plans and if the user has to use 2G then have to recharge their sim card with the 3G data pack. Now coming to the cascading modems/routers here we are using D-Link DSL-2730U (Hardware version: V1) you can also do the same for other routers. We basically know that the ADSL2+ modems have a DSL port with Wi-Fi and LAN for connecting the router to the PC.
