Setting up your BYO modem

In this article, we'll help you set up your own modem on our network. Whether you're reusing a modem from a previous provider or setting up a new one, we'll guide you through the process to help get you connected as smoothly as possible.

We support a range of modems, but as every device is a little different, it's important to check if your modem is compatible. If you run into any issues, we'll do our best to get your nbn® modem working, though support for non-Optus modems is limited.

Before starting

Is your modem compatible?

To work with our network, your modem should:

Be less than five years old (recommended)
Support nbn® connections
Allow configuration for DHCP (Dynamic Host Configuration Protocol)

How to check:

Look for the brand and model number on your modem.
If you're unsure, search online for your modem's manual, which often includes configuration instructions, including how to enable or adjust DHCP settings.

Understanding your connection type

Some internet providers use different settings to connect to the internet. At Optus, we use Internet Protocol over Ethernet (IPoE), which is much simpler, but it may mean you will need to change how your modem or router is configured to connect to the internet.

If you're switching from one of the below providers, you may need to adjust your modem's settings.

Providers that typically use Point-to-Point Protocol over Ethernet (PPPoE) (may require changes):

TPG	iiNet
Vodafone	iPrimus
Dodo	MATE communicate
Exetel	More Telecom
FlipTV	Spintel
Internode	Tangerine Telecom

Providers that typically use IPoE (likely no changes needed):

Telstra	Belong
Aussie Broadband	Buddy Telco
Amaysim	Superloop

Connecting your modem

Modem configuration

Our nbn connections use an Internet Protocol over Ethernet (IPoE) configuration. Some third-party modems are set up to use a different config by default. Note: Check the back or bottom of your modem, it may have a website listed or the product name to help you limit your search. To update your settings:

Find your modem's login details (often printed on the back or bottom of the device).
Connect a device (laptop, tablet, or phone) to your modem via Wi-Fi or Ethernet cable.
Access the configuration page by typing the modem's gateway address (commonly 168.1.1) into your browser's address bar.
Log in using the provided username and password (default is often admin / admin).
Adjust the network settings as follows:


nbn username	None
Encapsulation	IPoE
Host configuration	DHCP client
Connection type FTTP, HFC, FTTC, Fixed Wireless	Ethernet WAN
Connection Type FTTN / FTTB	FTTN / FTTB: VDSL2 Annex B (with Vectoring)
VDSL2 specific settings for FTTN/B Also refer to nbn specification	Modulation: VDSL2 Annex B (G.993.2)
	VDSL2 Profiles: 17a and 30a
	G.INP / G.998.4: Enabled
	G.Vector / G.993.5: Enabled
	SRA (Seamless Rate Adaptation): Enabled SOC / ROC: Enabled
VLAN ID	Disabled/None
