Airtel Beetel Modem + Netgear WGR614 Wifi Router

There are a couple of articles available on the internet explaining how to set this up but I after playing around a lot I realized that there are much easier ways of setting up a connection such as Airtel / BSNL / Tata with your own Wifi router such as Netgear / Buffalo / Linksys.

The most widely published explanations involves converting your ADSL Modem / Router (Beetel) into Bridge mode thereby only making it work as a modem and making the Wifi Router (Netgear) do all the work.

While this works fine it involves changes to be made to the configuration of the ADSL Modem in terms of setup as well the requirement of the username and password to entered into the Wifi Router setup. Also once you do this setup you will lose access to your Modem, requiring you to unplug the wifi router to access it.

Will be descibing a method below on an easier approach to getting your wifi online without needing to know your password or change any other settings on the ADSL modem.

Step 1

Plug in the network cable coming out of the ADSL modem /router ( Beetel) into the network port of your computer / laptop.

The computer should automatically get assigned a ip address of the following series

This means that the ADSL modem address would be Type in the following address to access the page of the ADSL modem.

It is will pop up a username and password

username : admin
password : password

Other standard is admin / admin

Step 2

Click on Advanced Setup --> LAN, you should see the following page , or something very similar. This is fine , no need to change anything, though you may want to change your password for security reasons as this page can be access from the internet as well.

From the device Info ---> Summary Screen write down the Primary DNS Server address and the Secondary DNS Server address.

Step 3

Disconnect from the ADSL modem, switch on your wireless router, if you have a system with wireless, switch on your laptop wireless, it should connect to the wireless on the router. Otherwise plug in the network cable into one of the LAN ports of the router with the other end into your computer.

Let the router assign you an IP. It typically would be of the series ..

Type the following address to access the main page

It is will pop up a username and password

username : admin
password : password

Other standard is admin / admin

Step 4

You should see the following page

Make the following entries

Does your Internet connection require a logn ---> No

Account Name ---> Blank
Domain Name ---> Blank

Internet Connection

Check the box that says use Static IP Address
Enter the address as 192.168.1.x where x is a larger number larger than the number of system you ever plan to connect, in my case 20 so that it never gets assigned by the ADSL router.

The 192.168.1 needs to be the same that you used for accessing your ADSL router.( Basically now this router is part of the ADSL addressing system.

Check the box that says use the following DNS server
Put in the DNS address you have copied in the previous step

Step 5

In the advanced menu, click LAN IP Setup, you should see the screen below.

In the LAP IP Setup, enter the IP Address, the same as entered in the previous screen, 192.168.1.x, in my case

Enter the subnet as

Leave the other options as is.

Make sure the Use Router as DHCP option is Unchecked !

Step 6

Click on the Wireless setting tab , you should see the screen below

assign any name you want for your wireless connection. You can choose to have no protection but its unsafe. Its very important to password protect your internet connection. There are typically two types WEP and WPA. Make sure you write down the password you are setting because you will need this to connect wirelessly. The password in the above case is for WEP connection, it is the hexadecimal code.

Below is the option for WPA. You need to remember the passcode you have entered here. WPA is much more secure, WEP can be hacked, I've done it :)

Step 7

You are almost done , but pay attention. Power off both the ADSL modem / router and wifi router. Take the network cable and plug it into the available LAN socket on the ADSL Modem. The other end on the LAN cable need to be plugged in any of the Wifi Router's LAN sockets. Be very careful not to plug it into the WAN socket, this is a single socket, typically the Netgear Router will have 1 WAN and 4 LAN sockets. So I say again, the LAN socket only, if your still confused, just plug it into the middle socket. :)

You Wifi router is now working as an Access point and all the computers that connect to it will be assigned IP from the ADSL Modem / Router in the , series once you enter the password based on the protection you have choosen.

You are now up and running :)

Points to note

1. You can still access your ADSL router page with
2. You can access your Netgear Wifi router with the new address of

Dot .Net 3.5 SP1 Installation Error

The other day for one of our projects we needed to upgrade to SQL Server 2008. Part of the pre requisites was to have .Net framework 3.5 installed on the machine. The DVD had the install for the framework but it just wouldn't install.

The setup would unarchive all the required files, and fire the setup program. The progress bar would increase all the way upto 95 - 98 % and just hang. I am talking about the full package and not the boot strapper. Tried after a couple of re boots but exactly the same problem on a couple of my machines, all running XP Pro SP2.

Did some readups and a few people have had some install problems. The solution for this kind of problem is to disable all your network adapter. Go to the Network Connection menu, right click the connections and say disable. Once this is done, run the install for the full package, it should go through rather quickly with the Microsoft EULA popping up as soon the setup progress finishes.

Don't know why this happens, am assuming that the package still tries to verify if all parts are available for install and wants to connect to the net but is unable to do so through our proxy servers.

Either way, this workround works well. You would need to install the framework for SQL Server 2008, Visual Studio 2008 and going forward probably a lot more applications that get developed on the microsoft platform.

The microsoft page is here

The full package install is here

Hope this helps, do drop me a comment would love to know.

We sometimes need to figure out whats running on our computers that have created connections for the outside world. The needs could be for check if you have any ad ware / trojans. The other reason is when we ourselves want to know if a certain program is running properly or what port it is listening too or figure out which system has connected into your machine.

There is this built in program in Dos called netstat but its very very basic and works only in the dos prompt. As always there is a lovely little stand alone program that is part of the sysinternal suite called tcpview. t doesn't need to be installed and has a zero footprint.

It shows all the application on your PC / Server that have open connection / established conections and the ports that are getting used. It also has a setting whereby you set the refresh time to update the current connections.

Sysinternals got bought over by Microsoft and now is hosted at microsoft

Hope this has helped you out. Do drop me a line !
