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.
