Configuring D-Link DSL-2520U Broadband modem/router for BSNL

I just thought of documenting my successful configuration data for D-Link DSL-2520U modem on BSNL broadband line.

In my setup I have connected the modem with DSL line and Ethernet cable with WAN port of Wireless router. I was able to access the modem configuration page through URL: http://192.168.1.1. Here I have dumped the configuration used by modem once it is successfully configured.

At the end of this post, you can find my configuration file, which you can upload with your userid and password as an attempt to get your job quickly.

Advanced Setup -> WAN -> Edit (if already a record is there) or Add

Here is Diagnostic Report:

Your modem is capable of testing your DSL connection. The individual tests are listed below. If a test displays a fail status, click “Rerun Diagnostic Tests” at the bottom of this page to make sure the fail status is consistent.

Test the connection to your local network

Test your ENET Connection: PASS
Test your USB Connection: DOWN - This is fine since I use Ethernet only

Test the connection to your DSL service provider

Test ADSL Synchronization: PASS
Test ATM OAM F5 segment ping: PASS
Test ATM OAM F5 end-to-end ping: PASS

Test the connection to your Internet service provider

Test PPP server connection:

PASS

Test authentication with ISP:

PASS

Test the assigned IP address:

PASS

Ping default gateway:

PASS

Ping primary Domain Name Server:

PASS

If you don’t get your Modem up even after following the above steps, you can try my configutation file mentioned in next section.

Configuration file to make your life easier:

Here is my settings backup file, which can be used later to restore the configuration. The backup can be taken by Management -> Settings -> Backup.

  BSNL DSL-2520U Modem Configuration File (2.6 KiB, 5,374 hits)

You may try downloading this file and edit the file for following line with your own userid and password.

userName=”YOUR-USERID” password=”YOUR-PASSWORD”

Once edited you can upload this file to Modem through Management -> Settings -> Update. Once updated Save/Reboot.

All the best!
