BSNL FTTH Modem Setup Guide


BSNL FTTH Modem configuration is easier than the ADSL Router. Optic Fiber router is also known as Optical Network Terminal (ONT), and it is used for authentication purpose. It also converts the optical signal to Ethernet in downstream & Ethernet to optical in Upstream.

Step I: Checks before BSNL FTTH ONT Configuration

Before starting the BSNL FTTH Modem Configuration, you should check the following things

  1. BSNL Optical Fiber cable is directly connected to FTTH Modem and an Ethernet cable from ONT is connected to PC or laptop.
  2. In ONT there are three LEDs Power, Fiber & Data which show the connection status. Power and Fiber LEDs must be green and stable, and Data LED is in a blinking state.
  3. IP address of your PC or Laptop should be selected as obtain IP address automatically. If it’s already there then go, you can directly go to step II.

For Windows 7 and above

Click on the Computer or Wi-Fi signal icon in the bottom right side of your computer.

Now you are connected to the Internet.

Configure Wi-Fi Router for BSNL FTTH connection

Now Your FTTH broadband is on, but it can work only on a single device as it has only one working Ethernet port. To extend this internet to all devices of your home or office, you need a Wi-Fi router, or Old ADSL modem may also work.

You may have BSNL Wi-Fi router. Just connect the cable from FTTH ONT to ADSL Router.

Connect the ADSL Modem to your PC.

Now login to the ADSL Router by putting IP address 192.168.1.1 in browser bar

Put username => admin

Password => admin

A new window will open. On the left-hand side click on Admin

Click on configuration

Then click on DHCP server

Just disable the DHCP server and click on Apply button.

Now you can access the internet on multiple devices, but still, you may not access it through Wi-Fi.

You need to enable the Wi-Fi and set the password for it. Or read my blog for BSNL Wi-Fi router setup procedure.

You can also use iBall, Belkin, D-Link Wi-Fi router to extend FTTH internet on multiple devices. In those devices also you need to factory reset them and after that disable the DHCP server.

  1. Dear Sir

    I have a fiber modem aont 100c i want to connect it to cisco 1800 router now there are only rj45 ports on the modem while the router has FE, aux and console ports and also the serial port. I want to ask you to which port should I connect the cable in the modem and the router.

  2. This is for the benefit of BSNL FTTH subscribers.
    My Modem: AONT 100C
    Router: D Link 2750u

    1. After installation by BSNL people, they have activated my phone after 2-3 days.

    2. I have connected RJ45 cable from Eth1 to laptop. I could not configure AONT 100C.

    3. Raised a ticket at http://www.alphion.in with modem model and serial number. They immediately guided me by email saying that ”
    The below said ONT is loaded with Bridged mode software at BSNL end.
    We have changed the mode into routed mode now,
    You will have to put your username/password in the ONT by logging in through 192.168.1.251.”

    4. Then it was very easy to configure ONT using method mentioned in this website. ONT configuration procedure was also provided by Alphion rep as email attachment. I could access internet in laptop. To make use of internet by other devices (to create wifi hotspot), we need router.

    5. coming to the router part configuration. Connect ONT to router at port 1 with rj45 cable. and with one more rj45 cable, connect router to laptop for router configuration. No need of rj45 cable from ONT to laptop. setting are described at length at youtube video https://www.youtube.com/watch?v=LWCrbJs3opQ

    Njoy your FTTH.
    My plan: unlimited Fibro Combo ULD1045C35 Hyderabad. 50 Mbps speed upto 150 GB . Post FUP, 4 Mbps.

    Speedtest results:
    With just modem and Laptop (wired connection): Around 45-50 Mbps.
    With wifi in laptop: 35 Mbps.
    With wifi in mobile: varying between 20 to 50 Mbps. I have seen 50 Mbps (download and upload speeds) sometimes.
    I am happy with these speeds. But, have to wait and watch how reliable this is.

  3. I have had BSNL FTTH connection 3 months back . First I bought D-Link For 816 WiFi router , it worked fine for few days but time and again it tended to reset itself on its own. When contacted the BSNl guy , he told me that D-Link always have such problems. He offered me airpro WiFi router , but the problem with this router is that it’s WiFi range is very limited and I cannot enjoy the speed of FTTh because of this . please suggest me which WiFi router is best for BSNL FTTH. I am based in Ranchi, jharkhand.
