Configuring BSNL MTNL Internet on D-Link Wireless N 300 ADSL2+ (DSL-2750U) Router

Hi friends,

I have bought a Dlink adsl2+ (DSL 2750U) wireless modem last week . But when i try to configure with our BSNL broadband,faced bit struggle to get out from this config issue.  so i google for solution, a blog (Irfan Tech info) clearly give detail info about this issue

Configuring The modem

Physical set up
Unpack your router. Connect the power adapter and switch on. Now the power led will be lit

Connect a LAN cable from your computer to one of the four yellow LAN ports. And see whether the corresponding LED start blinking

Now wait sometime so that the router will assign an IP to your computer.

Accessing Advanced setup using any browser

Go to any web browser like Google Chrome or Firefox ( or Internet Explorer :-P)

Type "http://192.168.1.1" as the URL and enter

It will ask for password. Type password as follows:

Username: admin
Password: admin

You will be welcomed by a page as shown in Figure

Go to Advanced Setup and Click Add

Now Add VPI values as 0 and VCI as 35 for BSNL and 32 for MTNL.Select DSL Latency : Path 0

Select DSL Link Type: EoA

Connection mode: Default

Encapsulation mdoe: LLC/SNAP - BRIDGING

Service Category: UBR Without PCR

Select IP Qos Scheduler Algorithm to Strict Priority and then Save
Now go to WAN Service and the click Add

In WAN Service Interface Configuration, Just click Next

Now in WAN Service Configuration, Select "PPP over Ethernet"

In the next page , you have to set your service provider username and password. If you don't remeber the password, Look at your Broadband Bill issued by ISP. In case of BSNL, Username is printed at the top-right corner. It is of the form "yourname STD-CODE PHONENUMBER AREA". Eg : "xy1142125227_ncdl" . For password Contact your ISP. In case BSNL, they keep it as "password" only. Keep rest settings as default.

In Routing default gateway, Just click Next

In DNS Server Configuration, I recommend to use some Public DNS servers like OpenDNS (See more about advantages of OpenDNS here) or Google DNS. So Select "Use the following Static DNS IP Address" and Add Primary DNS Server: 208.67.222.222 and Add Secondary DNS Server: 208.67.220.220.

Now in WAN Setup: Summary, Just skip clicking Next

Done. Now just reboot your router

Rebooting Router

Go to Management then Reboot in the Menu bar

After reboot, Your Router gets connects to Internet. This can be confirmed from the blinking of LED with an Earth icon .

Troubleshooting

If some error happens, just go through the below steps.

Make sure your LAN wire is connected. For that Go to Command Terminal in Windows or Bash/Shell terminal in Linux. Type the

command ping 192.168.1.1. You should get ping reply a shown in figure.

If the above is okay, Cross check your ISP Username and Password you typed in Step 10.
