Unpacking – D-Link Wireless N300 ADSL2+ Modem Router DSL-2750U

I have my good olden Starcom Type 2 Modem-Router given by BSNL, when I was in Coimbatore. It was working fine. Recently I’ve been facing problems when the modem is restarted after switching on the electrical supply. Unfortunately the router took 15 or 30 minutes to stabilise itself. Even sometimes, I need to wait for more than 45 minutes.

I ‘believed’ it would be the problem of router, as I am unable to access the modem configuration page during this stabilising period.
After a week of waiting period, the problem doesn’t seem to be resolved. I’ve planned to migrate the router, which would solve the problem.

My immediate options where Linksys or NetGear. Unfortunate, though it was the electronic store belongs to a trusted group of India, they had D-Link alone, that too only one, DSL-2750U! This is the story of my selection!

The Migration

The Migration contains the following steps

1. Note Down the ATM and WAN service details from the older router

2. Note Down the username & pwd given by the ISP

3. Connect the New Router and open the config page

4. Enter the ATM and WAN interface details. Enter the username & password given by ISP.

(Please note, BSNL officials can do this. But you need to go to your exchange with your router to get it configured)

For BSNL, I found the following settings.

pppUserName.value = xxxx
pppPassword.value = xxxx
pppoe service name = bsnl
authentication method =  auto

Enable NAT
Enable Firewall
Enable WAN Service
Service Name pppoe_0_0_35_1
PORT / VPI / VCI:     0 / 0 / 35
Connection Type:     PPPoE
Service Name:     pppoe_0_0_35_1
Service Category:     UBR
IP Address:     Automatically Assigned
Service State:     Enabled
NAT:     Enabled
Firewall:     Enabled
IGMP Multicast:     Disabled
Quality Of Service:     Disabled
Default Gateway:
Primary DNS Server:
Secondary DNS Server:

Unlike starcom, this is a two step process in D-Link Console.

1. Add Layer-2 Interface atm0

2. Enable WAN service ppp0

The username, password, DNS etc will be given in step 2. But the automatic option of the WAN interface picks up the DNS automatically.


Connecting to GPRS or 3G from Vista with Samsung Omnia – HowTo

This may be a nice event yesterday, when I need to couple my mobile with Vista based laptop. Here comes a howto!

  1. Power on your laptop and login. make sure that it is not connected to internet.
  2. Power on your omnia pro and connect it with laptop (I used USB)
  3. In the main menu of your mobile, choose Internet Sharing
  4. You will get internet sharing window, select USB as your PC Connection and the GPRS/3G profile under network connection
  5. Press Connect!

Thats all!

I am able to reach 130~150 Kbps with BSNL EDGE and 15 to 25 Kbps (!!!) with BSNL GPRS connection. Amazing upto 2.8 Mbps with 3G network!

BSNL 3G – to be or not to be!

Recently I became a frequent traveler. I evaluated many fast – wireless internet solutions like photon +, reliance bb etc. They are good enough to give me good speed where ever they have coverage. To have a cost effective solution, I got a BSNL 3G data card from Coimbatore. After 2 to 3 months, here comes my review.



I checked the service in Coimbatore, Tiruppur, Erode, Ariyalur, Chennai and Tiruchy. Most of the places are not announced officially. I guess, testing is in progress.

Chennai, Erode, Tiruppur are one among the best. I am able to reach peaks. Email with attachments are getting downloaded at no time. Browsing is pakka. I am able to reach the same speed offered by photon + or reliance broadband wireless highspeed internet.

Coimbatore – I am not that much satisfied. Though it is good inside the city, it is very bad at the suburbs like Singanallur which is just 8kms away from central part of CBE. In addition, it is frequently getting disconnected inside the city.

Tiruchy is not implemented fully I guess, since I am able to connect only with Edge, though it shows 3G icon.

My recommendation is – BSNL promises all the district headquarters will be covered with BSNL 3G before end of this year. Where there is no coverage, GPRS or Edge is working fine (I tested in remote places of Tamilnadu. I am able to reach 100 KBPS max). If you want a cost effective solution, You can select this. I want BSNL to be more sensitive towards this because their support, service are worst in their categories!
