Dlink Router 3G Configuration for MTNL BSNL Airtel


In one of my previous post I have dealt generic 3G configuration of D’link Modem/Router (2750U) for any SIM. But lot of people are mailing me to write specific SIM configuration. That’s is why this little repetitive post is being written.

I will not deal with all the basic configuration here, for that look at d’link 3G configuration post.

Assuming that you have read the suggested post and ready to tweak it for your SIM. If you will notice that there are just few things which differs from sim to sim. In previous post’s step 7 you need to make sim specific changes.

For MTNL Users:

Account : mtnl

Password: mtnl123

Dial_Number: *99# (MTNL says that you can leave it blank too)

Net-Type: TD-SCDMA

APN: mtnl.net (Both for Delhi/Mumbai)

For BSNL Users:

Account: bsnl

Password: [blank]

Dial Number: *99# or *99***1#

Net-Type: TD-SCDMA

APN: bsnlnet

NOTE: This BSNL APN is valid for these states: Haryana, Punjab, UP(East), UP(West), Himachal Pradesh, Rajasthan, Jammu & Kashmir, Jharkhand, Bihar, Kolkata, West Bengal, Orissa, Assam, North East, Adman Nicobar, Maharashtra, Gujrat, Madhya Pradesh, Chattishgarh, Karnatka, Andhra Pradesh, Chennai, Tamil Nadu, Kerala.

For Airtel Users:

Operator : airtel

Password: [blank]

Dial Number: *99***1#

Net-Type: TD-SCDMA

APN: airtelgprs.com

NOTE: If you feel that these settings are not working then make a call to airtel call center and ask them APN for 3G. Rest of the settings will remain same, although you can cross-check them too.

The point here is to note is that almost all major mobile carriers are now using a common APN for all the states. So, if you have free data roaming then you don’t need to change settings from state to state. If network provider is providing 3G in a state then these settings can be considered as default settings.

Get High Speed Internet from MTNL at Lesser Price

MTNL hai toh sahi hai. It’s MTNL tag line. I am not a very big fan of MTNL but I appreciate their work when they something good for country. Being a govt company, they overlook service matters. If you own a landline connection from MTNL then I am sure that you must have suffered with long (many days) downtime. You complaint and they overlook the matter. They do work whenever they get time. That’s why they are going out of business.

You must be wondering why am I writing this article then and suggesting you to use MTNL internet connection. Well, as far as internet is concerned we mostly rely on wired connection and often don’t look at other alternatives available to us. This post is about that alternative.

MTNL offers 3G service named as MTNL 3G jadoo. If you are living in Delhi or Mumbai then you must be aware of it. They offer some nice plans. One is for 6 months and other is for a year. I must say that the price is really competitive and somewhat awesome.

In Delhi 6 months plan is for just 4500/= for 200GB. (For Mumbai it’s 100GB)

and for a year you are supposed to pay Rs. 5000/= for 100GB

If you are a heavy down-loader then use 6 months plan and others can use yearly plan.

MTNL 3G yearly plans

More Details: MTNL 3G Tariff Plans

Comparison : 3G with other MTNL Plans

For MTNL landline if you choose to get their minimum unlimited plan which is for Rs 599/= plus modem charges Rs. 75/= plus if you made some additional phone calls. Bill rotates somewhere around Rs. 770/= per months. On the other side, if you choose their 3G plan  4500/= for 6 months your effective bill will be Rs. 750/= months. I know that’s there is not much of a difference. That’s my point. Price is same if you choose Landline or wireless 3G. The main difference is speed.

Speed Comparison

For landline connection you will get 512Kbps but for 3G you will get awesome 2.1 Mbps. Sometimes it crosses that speed too. So, you will get 4 times better speed than landline for same price.

Someone can say that it’s not Unlimited! I agree, there is a cap, but 200GB for 180 days is not a bad deal. More than a GB data everyday. Think about it.

Service Comparison

I know I am comparing MTNL with MTNL which is a little absurd but this comparison is worth understanding.

3G is a wireless service, so you will not get much downtime unlike MTNL landline long downtime because of cable fault etc.

Even MTNL’s 3G service is not up to the mark. It often gets disconnect while working, this might be a node to node problem. If you disconnect the dongle and reconnect it again then it gets connected. At cheap price this (few seconds or minutes) downtime can be handled.

If it’s a bad weather then yes, 3G might give you less speed but in any case it’ll be more than 512kbps.

Problem / Solution with 3G

3G requires good signal strength. If you are planning to use it within the building then lot of obstacles will downgrade the speed.

What I have done is, planted my 3G dongle (I had to switch to DLink for this) in a 3G wifi router at roof top. That way I get strong 3G signal and wifi serves this highspeed within my house.

Configure Dlink Router for 3G Dongle for Any Sim

Dlink is one of my favorite hardware provider but this time I did the mistake of trying other hardware like TP-Link. After so much drilling I have found that it’s not possible to use MTNL Dongle with it. MTNL 3g Jadoo dongle provided by Teracom is a weird peace of hardware. I have found that there is hardly any 3g router that supports it. So I have decided to drop this dongle and planed to use MTNL sim into a different dongle. Which can support a 3g router so that I can use MTNL 3G with all my devices as a wifi in my home.

I Tried TP-Link But..

I tried TP-Link 3G router before trying D-Link because the shop-owner told me that it is a good brand and works with almost any dongle. I bought it and returned back to home. I was feeling little excited that finally I have solved the wifi problem (Wifi Problem?? – It’s a long story. Dump it for the time being). I began testing mtnl 3G jadoo dongle and anticipating that it should work without realizing that teracom is not listed into the supported dongle list.

After drilling for more than 10 hours and reading everything available on internet about this specific problem, I finally realized that this is not the right time to end the story. MTNL 3G jadoo dongle is not supported by TP-Link and not even by D-Link (need explanation? Keep Reading).

Time to Try D-Link 3G Router (DSL 2750U)

I had a word with the shop owner and because he made me sure that TP-Link would work he agreed to accept the fact that TP-Link will not work in this case. I don’t blame chiptek (name of the shop). Shop Owner helped me so much through out the process, he made numerous calls for me to resolve the issue (rarely seen in India). Stories apart, he aggreed to change it and offered me D-link (Costly than TP-Link). He told me that he had made calls to field expert and even on D-Link MTNL 3G Jadoo dongle won’t work. You have to buy the supported dongle with D-Link. I was keen to end the story so I bought D-Link Dongle too.

I came back and inserted the MTNL 3G sim into it and things have started working after some changes into the router (Defaults will not work).

Configure D-Link 3G router for Dongle (USB – Stick)

1) Insert MTNL 3G sim into D-Link Dongle. Make sure internet is active on the sim. It’s a common mistake when you try something new. All bits and pieces must be working.

2) Power up the router and insert the dongle into USB socket. You will see the anchor sign (usb sign) has started blinking. Not its time to configure the router.

3) Because it’s a new router so currently it’s open to access (NO WAP/WEP KEY – unsecure). Open your browser and type

4) ID: admin, PASS: admin
5) Once you are logged in go to ADVANCED on top click 3G Configuration on left and if action status is undial then click Undial


6) Once you click undial, after few seconds Edit button will become active and click it.


7) Now you can edit settings of your 3G dongle. I am publishing MTNL settings because I am using it. You can ask your service provider for these settings. If you are using AIrtel, Reliance, Vodafone, Idea or any other 3g provider, make a call to their call center and ask them these settings.

For MTNL Delhi these settings are:

Account: mtnl

Password: mtnl123

Dial_Number: *99#

Net-Type: TD-SCDMA or WCDMA (Whichever your service provider says, although I doubt that they know these terms. I am using TD-SCDMA, you can use that too and test).

APN: pps3g (mtnl provides lot others too. But for the time being use pps3g).

OnDemand: check the box

Go down and Click APPLY.

8) Once you click Apply, it will start modem will start dialing the network with these settings. Wait you few settings

Inform: Connecting, dial on demand, Auto Dialed

will turn into

Inform: CONNECTTED, dial on demand, Auto Dialed



Now it’s time to set wifi secutiry Key otherwise your open connection can be used by anyone in your neighborhood.

Click Advanced Wireless –> Security Settings


Go down and set Pre-Shared Key and click Apply.


Once you set this pre-shared key, you have to connect your computer again and this time it will ask the key.

That’s all. Hope this guide will help you to set and configure D-Link Router with 3g usb-stick and any service provider SIM card.
