General NBN HFC router setup advice

This article will provide some general router (or modem router) setup advice which may help you set up a third-party router or modem router for Westnet NBN™ HFC broadband. 

If your modem router was supplied by Westnet, you'll find its setup guide in Westnet Modem Resources.

Using a third-party router for NBN™ HFC means that included NBN™ Phone service (and any calls) will not be available.


  • An active NBN™ HFC broadband service. We'll send you an SMS and/or email when your broadband service is activated.
  • An NBN™ HFC Connection Box. These devices remain the property of NBN Co and should not be removed once they are installed at an address. If you advised us that there was no Connection Box present when you placed your order, one will be installed as part of your connection.
  • An NBN-ready modem which allows you to change the VLAN setting. This is required to configure your NBN™ HFC service.
  • The power supply cables that came with your modem and Connection Box. If you need a replacement for any reason, take care to note the Rated Input on the device's barcode sticker (e.g. 12V/2A) and buy a matching cable.
  • A coaxial fibre cable (one is typically included with the Connection Box).
  • A Cat 5e or Cat 6 Ethernet cable (at least one is typically included with a modem or the NCD).
  • Optional to connect additional computer(s) to your router via Ethernet: Additional Ethernet cables (at least one is typically included with a modem, usually a Cat 5e). There are different kinds of Ethernet cables. If you're purchasing one from a store, we recommend Cat 6 or Cat 5e. A Cat 5 cable is not recommended because it may not support the speed capability of your NBN™ service. 


  1. Find the cable wall socket that has your NBN™ Connection Box connected to it - this is commonly found in the main living room space or bedrooms, but sometimes they're in the kitchen area. The Connection Box may look something like the photo below.

  2. You'll also need two available electric outlets - one for your modem, and one for your NBN™ Connection Box. If you need to use a double-adapter, power board or extension cord this should be okay, but if your modem or Connection Box ever seems to have power issues the first thing you should try is plugging the power supply cable directly into the electrical outlets on the wall.
  3. Make sure your Connection Box is plugged in securely. Its power supply cable should connect its power port to an electrical outlet, and the coaxial fibre cabke should be securely screwed onto the cable wall socket and the Connection Box's  You may turn on the power at the outlet wall now (the Connection Box does not have an on/off button) or wait until you've finished plugging in the other cables.

  4. Likewise, take your modem's power supply cable and use it to connect your modem's power port to an electrical outlet. You may turn the modem on now or wait until you've finished plugging in the other cables. 


  5. Take your Cat 5e/Cat6 Ethernet cable (this is typically yellow, blue or grey but other colours are possible) and plug one end into the Connection Box's UNI-D 1 port.

  6. Plug the other end of the Ethernet cable into your modem's WAN port (example shown below).

  7. If you have a computer nearby that you'd like to connect via Ethernet, take an additional Ethernet cable and plug one end into any one of the modem's Ethernet ports - most modems have 4 of them (example below).

    Ethernet ports are most commonly labelled "LAN" or a symbol showing objects linking together. If you're uncertain, check the manufacturer's website for support information.


  8. Other devices can be connected via WiFi. Modern modems are typically programmed to begin broadcasting WiFi as soon as they're turned on and have finished booting up. Even if the modem isn't connected to the internet, the WiFi can be used as a local connection between the modem and a computer/WiFi device to access the modem settings.

    If your modem broadcasts WiFi by default, it will have a default WiFi network name (may be labelled "SSID") and default WiFi password (may be labelled "WPA", "WPA-PSK", etc.) which you can use to identify and connect to the WiFi. These details may printed on a separate card included with the modem, but they will also be printed on the barcode sticker on the back or underside of the modem (example below).

    If you're not sure how to connect your device using the default WiFi network name and password, see Connecting to a WiFi Network.


  9. Your setup should look something like the example below. The next step is to configure the modem settings by following the instructions below.


Note: If you're using a modem purchased from Westnet, please download its setup guide from Westnet Modem Resources instead of following the steps below.

  1. To access the modem settings, you'll need a computer, laptop, tablet or smartphone that's connected to your modem via Ethernet cable (recommended) or WiFi.
  2. Open your web browser and go to your modem's default gateway. Some of the most common addresses are, and

    If these addresses don't work for you, the easiest way to find the modem's default gateway address is to check the manufacturer's website for support information. Alternatively, if you have a desktop PC or Mac you can follow the advice in this article to find the gateway address.

  3. You'll see a login page. If there's a username field, the default username will almost always be admin (it may even already be filled in). The default password is typically admin or password.

    If you can't log in with these settings, please check the manufacturer's website for your modem's default login settings. If the modem is secondhand or you've used it previously, it may already have custom login details set. If you need to, you can factory reset the modem to return it to the default settings.

  4. Important: From here, it gets a little tricky to offer general advice for all modems. The layout of modem settings pages can vary greatly for each different modem. If you get stuck or it's not clear where you should enter your broadband settings, you need to check the manufacturer's website for support information.
  5. Ideally, your modem will have a Setup Wizard or Quick Setup that will run automatically the first time you log in to the settings, or there'll be a fairly obvious button to launch it. Some modems may include a Setup CD that will run this Setup Wizard for you and then send the settings to your modem.
  6. The Setup Wizard should run you through entering the required broadband settings, step by step.

    - Any Mode/Modulation/Interface setting should be set to Ethernet or WAN.
    - The WAN Type/Connection Type/Encapsulation setting should be set to PPPoE. You'll also need to enter your broadband username and password which can be found on the email we sent you when your service activated. Be sure to include the domain with your username, e.g.
    - The VLAN or VLAN ID setting must be set to 2. In some modem settings, you may need to select the VLAN networking standard, 802.1q.
    If there are any broadband settings in your modem's Setup Wizard that aren't specified above, it should be fine to leave it as the default setting.

  7. Most Setup Wizards will run you through the WiFi settings as well as your broadband settings. This will give you the opportunity to change the default WiFi network name (SSID) and WiFi password (WPA/WPA2-PSK) to something you'd prefer.

    You should write down your custom WiFi details for easy reference in the future, but you should not set your WiFi to have no password as this is a security risk.

    Note: If you're accessing the modem settings over WiFi and you've changed the WiFi settings, your device will disconnect once the new settings have saved. You'll need to reconnect using the new WiFi details. If your device appears to remain connected to the WiFi but you can't get online, you may need to go into the device's WiFi settings and select "Forget this network" before reconnecting.

  8. After completing the Setup Wizard and saving your settings, give the modem some time. Some modems reboot automatically after every new configuration, while others simply need a few minutes to apply the settings and get online.
  9. Take a look at the lights on your modem. Most should now be green, blue, purple or another "positive" colour. Many modems have lights that flash to indicate connection activity, so you shouldn't be concerned if any lights are flashing unless the manufacturer's support information specifically advises that flashing lights indicate a problem.

    If any status lights appear red, orange or another "negative" colour, and you are unable to get online and browse websites, please check the manufacturer's website for support information. Remember that third-party modems are not supported for NBN™ HFC so if you need to call us on 1300 786 068 for assistance, we can only help you set up the modem supplied by us. Similarly, if the ONLINE light on your Connection Box is off, please call us.

  10. Hop on one of your computers or WiFi devices and try to visit a website. If it works, your broadband is up and running!


If the ONLINE light on your NBN™ Connection Box is not lit, please give our friendly Support Team a call on 1300 786 068 and we'll be happy to help.
