How to set-up your BSNL broadband wi-fi using Landline.

This tutorial is going to teach you to set up your BSNL wi-fi broadband on your own.This is pretty simple and going to save you the installation charges and give you the satisfaction of fruit of labour.So here is how you go through with it.
 1. Firstly, you need to have a BSNL landline connection to avail the broadband facility.In case you already dont have it, get it.
 2. After you get the landline connection,you need to apply for the broadband connection with yout ISP ( Internet Service Provider). After your connection is through  you will get a username and a password.
3.Now you need to get a wi-fi modem which either you can purchase from market or can be provided by your ISP.Now most widely used Wi-fi modem is Dlink.In this tutorial we are gonna take the example of D-link DSL 230u.
4. Your modem comes with following entities in a package.

• A Modem cum router device which has four ethernet ports(Blue outline in the figure below) and a single DSL port(white outline).
• A splitter which has two ports on one side and a single port on the opposite site.
• A DSL phone cable
• An ethernet cable.

Now DSL cable and ethernet cable look similiar to each other but remember ethernet cable has wider ends.

5. Now make physical connections as illustrated in the diagram below

6. After you have already made the connections.You need to configure the Modem for the first time.For that ,you can either use the CD that may or may not be included in the package or you can do it manually.For that you need to connect the router to your laptop PC so that effective network looks exactly like in the Fig 4 below.

Needless to say,the modem needs to be plugged in for the power.Configuration is pretty easy and self explanatory.You need to type a given IP adress in your browser and go to the modem interface.You can enter the default values there in the set-up wizard and you are ready to go.
