How to use your WiFi ADSL Modem cum router as a Wireless access point only

SHARES

Due  to prolonged serviceability of underground cables, recently I was compelled to change my BSNL broadband connection to WiMax . In WiMax connection the output of CPE (Customer Premise Equipment) is an Ethernet port, which can be directly connected to PC for accessing internet. To share the connection for multiple PCs you have to use an additional Wireless Router (For WiFi) or LAN switch. I’ve used my spare  D Link 2730- U WiFi router as a Wireless Access Point to convert the WiMax connection to a WiFi .

D Link 2730 U is an ADSL Wireless router with one WiFi port and four LAN ports. If you want to use this router as a WLAN access point only, the first step is disabling DHCP. For this connect the router with your PC with WiFi or Ethernet cable. Access the Modem Admin page by entering http://192.168.1.1  in browser address bar. Use the default user id “admin” and password “admin”.

Go to the LAN sub menu under Advanced Setup.  By default the DHCP server is enabled. Here you have to Disable the DHCP server. After disabling the setting save it and reboot the router.

Now you can connect Ethernet input cable to one of the four LAN ports of the router. Internet connection on this port will be bridged to other three ports as well as WiFi port. Now the device is converted as a simple WiFi access point. You may be required to enter the IP to your WLAN/Ethernet adaptor of PC/Laptop to establish connectivity (If the network shows “Limited Connectivity”) See the image. In my case the default IP address of the WiMax CPE is 192.168.0.254 which is used as default gateway.

Here I didn’t changed the default IP address of the ADSL router (192.168.1.1) just used the router as a bridge only. The same method is applicable to other routers also. Here the points to Note:

  • Get the IP range of the connection which you want to extend. (Connect to network, in command prompt enter ipconfig /all. You will get the IP address and the connected default gateway).
  • To avoid IP conflict, change the IP address of your WiFi router in the same range.
  • Disable DHCP and NAT settings of WiFi Router
  • Connect the input to one of the LAN ports.

    Hi,
    I have just bought a new Digisol DG-BG4300NU adsl router with 1x RJ11, 4x LAN & 1x USB Port.

    Problem I am facing is that the Broadband connection is coming through a CAT5 (4 wires) cable.

    Now My ISP guy says that this Digisol DG-BG4300NU is of no use because it does not have WAN port (and extra Ethernet/RJ45) port where i can plug in the RJ45 connector provided by my ISP.

    I have 4x LAN RJ45 connectors but He says that those are in series and nothing can be done with them.

    Really need help to sort this out…

    If someone knows the possibility of making/configuring any of the LAN ports on Digisol DG-BG4300NU as WAN/Ethernet port where it accepts the connection from the ISP and that can be used over wi-fi?

    I tried making the ISP cable as cross-cable and connected to my router but that did not work…

    :-(

    • Which is your ISP? Are you using any dial-up option (browser based authentication) to connect the broadband? If no such authentication is required, you can very well use the WiFi port of the Digisol modem.

    Hello Frnds
    I was able to use my DLink 2730u router on Reliance Broadband,
    but the problem is i am able to connect only one device at a time by putting the ip address, gateway, and subnet mask,
    If i put the same info on other device and try to access it would say ip conflict that is obvious,
    any help would be appreciated
    thank you

  • Akshay

    I hv d-link wifi modem on ground floor and I want to use its range to my 3rd floor
    So what do I need to use wid it which enhance its wifi range with the same wifi modem

    Pls suggest me

    • For a three floor building a single WiFi Modem will not be sufficient. You have to go for a good range extender also.

  • Sajeev

    Hi, thanks for the article. I’m not a tech geek and I don’t understand everything. The help I want is regarding my BSNL broadband connection. I have a digisol modem and wifi is available nearby the modem, but not in my office on another floor. I have a cable from the modem in the office, so I get access to the internet. What should I do if I want wifi in my office? If I get a router and plug in the cable from my modem, will that work? Do I need to configure the router first? How do I do that? What router would you suggest? Thanks for your help.

  • Saugat

    How can I configure the static IP from ISP on the router to be able to use multiple wifi devices at the same time. Obviously if I configure the static IP at the device end, then it will only work one at a time.

    Sir,
    I have configured my BB VDSL modem as router with changing the modem ip address with one of my LAN ip address. one of mu LAN network cable connected to VDSL modem and we can access both LAN and internet at the same time in laptop or PC.

    Here problem is anyone on network if select their LAN TCI/IP setting as ‘ obtaim automatically’ then they are able to use the Broadband. I want to restrict it to particular PC and it should be accessble to all through wifi. But in LAN it should be restricted to particular PC.

  • I have Beetel 450TC2 ADSL Modem Router connected to ISPs RJ 11 (Phone Line – DSL) at ground floor of my home. All devices 3 laptops and 3 Android Phones (Yureka, Mi3 and Samsung S5) are connected over WiFi and enjoy good signal n speeds on ground floor and front half of first floor.

    I need WIFI n Internet connectivity at full first and second floor and possibly 3rd floor (if not asking too much)

    I have spare D-Link DSL-G604T and D-Link DSL-2640T, WiFi ADSL modem routers.

    Laptops n Smartphones get anything like 192.168.1.2 – 9 at max and even more when guests are here.

    I do not have option to connect the 450TC2 and G604T /2640T using wire (Phone or CAT 5/6 or Electric) as per design of house building.

    I cannot use G604T /2640T as primary router.

    I do see WDS setting in Beetel 450TC2 but not in G604T /2640T.

    I have not changed anything on 450TC2, however i have RESET G604T /2640T and then changed following using wired lan connection between PC n G604T / 2640T

    Hi Sujith . Excellent article. Thanks a lot.
    Just one doubt . I’m using TPTL broadband with RJ45 ethernet and router which I have is Dlink 2730. Broad band have the browser based authentication system . Will this process work

  • Pradyut Dhara

    Hi Sujith,
    Thanks a ton for this article. I have Ortel Communication Cable Modem and wanted to set up WiFi using DLink DSL-2750U. Have been Googling for last one week and tried all suggestion to set up the WiFi in this modem but nothing worked for me. I had almost decided to quit seeing no output. Luckily i found this article and tried whatever suggested. Initially it was not working. Then i switched off the router power and connected the cable modem ethernet to Port4. Then, switched on the router power and let the router restarted. Voila!! The WiFi started working.Now,2 mobiles & 1 Laptop are connecting to the WiFi. Having set up the WiFi i was trying to access ADSL router admin page (i.e. http://192.168.1.1/) in order to strengthen the security. Unfortunately, the admin console page is not accessible by any ways (i.e. via Wireless , LAN). Tried unplugging the internet cable from the cable modem and then rebooted. The admin console page is still not reachable. Is there any other alternatives to make the admin console work? Please suggest.
    Thanks again from my bottom of heart for this blog/article.
    Best Regards,
    Pradyut Dhara

  • Suman

    Sir can I use my Nokia Siemens Modem+router provided by BSNL with Alliance Broadband

    • If alliance broadband is using a browser based authentication, then it won’t be possible

  • Rpk

    Thank u for ur advice.its working.

  • Rojo John

    thanks for your informative article. For me, this worked without doing anything. I used my D Link ADSL2+ Router (DSL-2730U) as a wifi router by just connecting the incoming LAN cable to LAN port 4 of the router. I was able to use wifi from this. only problem is i am not able to access the homepage of the router. I disconnected the lan cable. it worked.
