We have already published an article on the Configuration of D Link 2730 U WiFi Modem for BSNL and MTNL broadband connection. Now here the WiFi configuration and security settings of this Modem. You can very easily configure the WiFi with associated security features through the web interface. Remember – You have to configure the Modem in PPPoE Mode (Always ON mode) to get Simultaneous internet connectivity in all your PCs Laptops and other Smart phones.

In the page Click the Wireless Menu. Select Enable Wireless.  In the SSID field you can type anything to identify your network- The default SSID is “DLink”. You can change it to your Name or something like that. Select your country. Then Click the Save button.


Now go to the Security Menu

in WPA/WAPI Passphrase field enter a non guessable complex strong password- This is the password of your Wireless network. You have to enter the same in your WiFi Devices for getting connectivity. Select the WPA/WAPI Encryption TKIP+AES or AES. Apply/Save your settings.

MAC Filter (Optional for added security)

mac filter

MAC filter is an added security feature to safeguard your WiFi network from unauthorized intrusion.

MAC (Media Access Control) address is a unique number of each network hardware. This is actually the id of a machine . There will not be two network cards (Any type) with a same MAC address. It is a manufacture set hard coded one.

Through the MAC filtering, you can optionally allow or deny a specific WiFi device in your network. You need to enter the MAC address of the client machines in the Modem to permit or deny a specific machine. For instance– You have four laptops in a network and you want to enable MAC filtering. For this the MAC address of each machines to be typed in in the Modem for connectivity, means you have to save the addresses of all four machines in your Modem.

How to find MAC address

For Windows PC go to start > Run ant type cmd
Then type ipconfig/all and you will get some values as displayed.
Note down the physical address of WiFi adaptor – This is your MAC address.

Save your Settings and Reboot The Modem.

Now You can connect the Modem through the WiFi adaptors of your Laptop, PC or Smart Phones. While connecting it will ask the password which you have entered in the Modem.

  • Hi,
    I have a broadband connection of BSNL connected to my desktop through a modem supplied by them which works fine on my desk top. I have bought a D_Link DSL-2730-U model wireless 150 ADSL2+ Modem Router. I have connected it to LAN port 4 of BSNL modem. Though the wireless signal from the D-link is shown as strong in my laptop or nexus-4 phone. It displays that it is not connected to internet. When I tied to follow the instruction manual for installation on inserting their set up wizard CD in the desk top, the screen do not go beyond the page where it keeps repeatedly ask me to ckeck that ethernet cable is connected and modem is power on. How can I activate the wireless router function of the D-Link modem connecting it to LAN port $ of BSNL broadband modem? Raghuram

    • You should use only one modem. Connect wireless modem to the CAT5/6 from the LAN card of PC to any of the four outputs from the wireless router. Go to chrome or any browser and type in the address bar and press enter. The router setting page will open. Default user name and password both are ‘admin’ follow the procedure given above and you can connect.

    also tell me whether i can use by bsnl 3g data card as an input source with my dlink 2750u or not so that i can use it as wifi.

  • G.CHAK.

    Sri Videshi Rawat Ji as well as Divyaiji I’m sure your problem concerns non working of OTHER WiFI devices like laptop(usually wifi provided),smart fones, phablets etc.wirelessly for net connection with wired Broadband of BSNL.
    From my personal experience U will definitely find result if U follow the process described in the write up above. I have tried it on DLINK2730U MODEM and it worked incredibly good on first attempt.Of course I didn’t try for Mac filter for addl.safety.

  • Anupam Chatterjer

    The name of my previous modem is BSNL ADSL 2+CPE/Wireless Router. It supports 4 fast Ethernet (10/100 Mbps) Interface. But I was facing some problems with its Internet speed some days ago, so when I saw the new D LINK DSL 2750U modem at amazon I decided to buy it. But before buying it I’am confused with it that it will provide connection in my desktop computer as well as provide a WIFI network to my android phone simultaneously or not. I would also like to have an advice from you that like my previous modem this new one supports 4 fast Ethernet Interface or not ? So please give me a perfect answer for my questions.
    What are the difference between dlink DSL 2750U & DSL 2730U modem ?
