Hi there and welcome to yet another of my tutorials. Here I am going to describe you how you can enable DHCP, Dynamic Host Configuration Protocol, in your standard BSNL broadband modem.

Are you the kind of person who does OS hopping and/or lots of reinstalls of Operating Systems ? Have you ever been pissed off by the fact that you always need to reconfigure the internet connection for the OS ? Do you use Live CDs often, and find it troublesome to reconfigure internet again and again ? Well, then worry no longer, as I am going to describe you how you can configure your modem, so that the OS uses internet directly, without being bothered with IP Address, Gateway Address, DNS Servers, etc…

DHCP, or Dynamic Host Configuration Protocol, is a protocol by which you can ensure that internet is supplied directly to a internet accessing device, without any special connection configuration. Multiple devices can be connected to the internet this way and you wouldn’t need to manually change their IP addresses to avoid conflicts. You can read up about DHCP in the link I just gave you, but its may be pointless to some of you; so I am not describing it here. The operating system only needs to be preconfigured to use the DHCP protocol by default. All distros, plus Macintosh OS have this feature. That accounts for 99.9999999% of live environments. All of them use DHCP by default unless you configure them to use something else.

Here is how you configure it:

1. Open your Web Browser.

2. Go to your modem’s IP address, which is usually 192.168.1.1

3. Type the username and password both as admin

4. This takes you to your modem’s Web Configuration Interface

5. Go to DHCP section.

6. Select Enable.

7. You will be asked to restart device and wait for 2 minutes.

8. Finish it and go to DNS section.

9. For High Speed internet, use OpenDNS servers.

10. OpenDNS servers are 208.67.222.222 and 208.67.220.220

11. Once again you will be asked for conformation to restart device and wait 2 minutes.

12. Finish it and turn off system.

Now, when you use the system, with a Live CD or a fresh distro, DCHP should be enabled and you can experience instant internet.

Good luck and happy surfing.

Note: This can be done on nearly any modem, with similar procedures. Refer to their manuals for variable data like IP Address of Router and Username/Password.
