Configure BSNL AIRTEL MTNL In Ubuntu - A Beginner's Guide

This tutorial should help you configure your BSNL,MTNL,AIRTEL Broadband Connection in Ubuntu . This tutorial is mainly for beginners who have no idea on how to get started with their internet connection in ubuntu . So here's a guide on that :


Since BSNL,MTNL,AIRTEL are DSL ISP's they have two ways of connecting to the internet . One way is the PPPoE mode , in this mode all you need to do is switch ON your router and your internet connection work . The other way is the Bridged mode , here you use a Dialer to connect to the internet.

Now while in windows , if you were in the PPPoE mode i.e. your internet connection worked as soon as you switched on your modem , then there is nothing much you need to do . Your internet connection should work plug n play . If you are still not able to access the internet , it is mainly because of a connectivity issue between your pc and your modem . If this is a wired connection , here's a small command you could type which should hopefully fix this . For this , Go to the Terminal(Applications->Accessories->Terminal ) and type sudo dhclient eth0 . This should give the eth0 interface an ip address from your router . If the internet connection works now , then all is well . If you still face issues and you are not able to access http://192.168.1.1 ( your modem's default ip ) , then you should try entering a STATIC IP . CLICK HERE for a tutorial on that . Now you should have internet access . If your able to access http://192.168.1.1 and still have no internet access then its mostly something wrong with your internet connection.

Now while in windows , if you were in the Bridged mode i.e. your internet connection worked by using a dialer in windows to connect your pc to the internet , then you would need to configure a dialer . For this follow THIS GUIDE to connect to the internet .

Thats it , you should now hopefully have a successful working internet connection in Ubuntu.
