Connect Computer Directly With ONT Internet

Hello All!

Today I’ll show you a simple trick to connect your computer directly with your ISP provided Optical Network Terminal (ONT) device.

An ONT is a mutiplexer device that Internet Service Providers (ISP) install at your home for a number of subscribed services, such as television, internet, telecommunication, etc. There is always a router connected with your ONT device that supplies internet to your home/office via cable (LAN) or wireless (WiFi).

The reason why you might want to connect directly to your ONT device is because in my situation my router simply died. It ended it life suddenly, all LED lights went off and my home internet connection was offline. I’m speaking specifically in context of United Arab Emirates (UAE)’s Etisalat connection. Etisalat installs an ONT device in every home and a router is connected to its WAN port which broadcasts WiFi and LAN based internet to your home or office.

Now why do you need router to connect to ONT anyway? What happens if you directly connect your laptop to the ONT’s WAN port using the ethernet cable?

It’s simple. The router performs two functions… one to dial internet through the ONT device, and second to allow multiple devices to connect to the internet at the same time using its DHCP (or static IP) infrastructure.

So if you’re experiencing something similar to my situation where your router has died and your new router will take some time to be delivered, you’re not entirely out of luck. You can still use the internet using your desktop computer or laptop.

Before You Begin

Few things you have to keep in mind when using this approach. First of all, your computer is not a router. It doesn’t have a DHCP network topology built into it. So when it connects to your ONT network, it connects directly and no other device can connect at the same time. That’s the router’s job. But since your router is dead like mine, you can only connect one computer directly to your ONT. However, there are software and techniques through which you can make your computer behave like a router and broadcast the internet signals (applications such as Connectify for Windows). I’m not covering that here.

Secondly, I’m showing this technique using Windows 10. It should be similar with Windows 7 and 8 as well. And with a little research you might find similar techniques for Mac and Linux on the internet. Just read the procedure below and search for Mac and Linux equivalents if you’re using those operating systems.

How to Connect Directly

You just cannot connect your computer directly with ONT and expect internet to work. ONT is a modem. It is a device provided by your ISP that connects to the ISP’s network, performs a handshake and then provides you the service. So for internet, usually there is another step of verification to be performed before internet signals can be relayed to your computer.

You must have received a user name and password from your ISP. In UAE, Etisalat provides a user ID card when a new connection is installed at home or office. That ID card contains user name and a password. In case you lost this card, you can get it reset from the Etisalat customer services shops. I don’t expect the call center to have the access to reset this.

  1. So to connect to your ONT modem device, connect your computer to the ONT’s WAN port using ethernet (LAN) cable.
  2. Go to Settings application, and click Network & Internet.
  3. On the left, click Dial-Up to open up settings for modem based connections.
  4. Click Setup New Connection. A new window will open.
  5. Select Connect to Internet and click Next.
  6. When it asks “How do you want to connect?”, click Broadband (PPPoE) option.
  7. Now enter your user name and password that your ISP provided you.
  8. Click Connect.

That’s it. Your computer will now dial connection using the ONT modem and connect you to the internet.

Hope this helped.

    1. Yes thats true. But what I’m explaining here is how to use the device without a router. You will still need your username and password for that.
