General ADSL2 modem setup advice

This article will provide some general modem setup advice which may help you set up a third-party modem for Westnet on-net or off-net ADSL2+ broadband.

If your modem was purchased from Westnet, you'll find its setup guide in Westnet Modem Resources.

Select one of the links below to jump to a query:

  • An active on-net or off-net ADSL2+ broadband service. When your broadband service is activated, we'll send you an email with your broadband username and password. You may need these details to get online.
  • An ADSL2+ modem router. If your modem was manufactured before 2010, please make sure it supports ADSL2+.

    Similarly, older devices may simply be "modems" and not "modem routers", which means it doesn't have the ability to wirelessly broadcast your internet as a WiFi signal in your home. These days the vast majority of modems on the market are actually modem routers by default, and we just call them modems because that's the norm. If your modem doesn't have a WiFi feature, you'll need to connect computers via Ethernet cables, or purchase a WiFi router separately and connect it to your modem so it can take care of the wireless.

  • The power supply cable that came with your modem. If you buy a replacement for any reason, take care to note the Rated Input on the modem's barcode sticker (e.g. 12V/2A) and buy a matching cable.
  • An RJ11 phone cable (at least one is typically included with a modem).
  • Optional for plugging in a computer via Ethernet: An Ethernet cable (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.
  • Optional for plugging a modem and a phone/fax into the same wall socket: An ADSL2+ line filter/splitter (one might be included with your modem).
  • Important: Once you have ADSL broadband, every phone or fax device should be plugged in with a filter/splitter to stop the phone signal interfering with your broadband, even if these devices are plugged into a different telephony wall socket. See Correctly filtering your hardware for more information.


  1. Find the telephony wall socket in your home. They're most commonly found in the main living room space or bedrooms, but sometimes they're in the kitchen area. It should look something like the photo below.
    Note: If If your home has the older 600-series wall sockets (typically the plug is a yellow square with 3 prongs), you’ll need to purchase an adapter that allows you to plug in a modern RJ11 phone cable. These adapters can be bought at all good electronics and computer stores.

  2. You'll also need an available electric outlet to give your modem power. If you need to use a double-adapter, power board or extension cord this should be okay, but if your modem ever seems to have power issues the first thing you should try is plugging the power supply cable directly into the electrical outlet on the wall.
  3. Take your modem's power supply cable and use it to connect your modem's power port (example below) to an electrical outlet. You may turn the modem on now or wait until you've finished plugging in the other cables.

  4. Take your RJ11 phone cable (these are typically white/grey and thinner than Ethernet cables) and plug it into the modem's DSL port (example below). This port will typically be labelled with "ADSL" or "DSL". If you're uncertain, check the manufacturer's website for support information.

  5. The other end of the RJ11 phone cable may be plugged in one of two ways:

    - If the modem is the only thing using the telephony socket, plug the phone cable directly into the telephony wall socket

    - If you also need to plug in a landline phone or fax, plug the phone cable into the ADSL port on a line filter/splitter, and then plug the line filter into the wall socket (example below).


  6. If you have a computer nearby that you'd like to connect via Ethernet, take your Ethernet cable (this is typically yellow, blue or grey but other colours are possible) 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.


  7. 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.


  8. Your setup may look something like the example below.

  9. If you haven't already done so, turn your modem on and let it sit for 10-15 minutes. If you have an on-net ADSL2+ service, your modem should use this time to retrieve your broadband settings automatically via our network.

    If you have an off-net ADSL1 service, you'll need to enter the settings as per the advice below. If you have ADSL2+, you may still need to do this if you can't get online.


  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. You'll find most of the settings you need in iiNet Group Broadband Settings.

    Your broadband username and password are unique to your broadband service and they are always required for a manual modem configuration. You chose your username and password when you applied for your broadband service, and these details would have been emailed to you when your service was activated. If you can't remember your username and password, please call us on 1300 786 068 for a hand.

    If there are any broadband settings in your modem's Setup Wizard that aren't covered in iiNet Group Broadband Settings (e.g. MTU) then 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, consider trying our troubleshooting guide for ADSL No Connection or No Authentication as one of these issues may be affecting you.

  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 you hit a Westnet webpage saying that you've got an incorrect username or password, you may need to return to your modem settings and re-enter these details. Remember that they're case-sensitive, so all capitals and lower case letters must be copied exactly and they should not include any extra spaces.
