How to help optimise your nbn™ FTTC connection at home*

When connecting to the nbn™ broadband access network, the following advice may enhance your in-home internet experience.

We want to help you get the most out of your nbn™ Fibre to the Curb (FTTC) connection, which is why we’ve created a short guide that explores frequently asked questions and provides easy-to-follow advice regarding the positioning of your equipment - whether you're setting up for the first time or optimising your connection.

There are a few things to keep in mind when installing and using your nbn™ connection.
Wi-Fi router/modem location
  • We recommend plugging your nbn™ connection box into the telephone wall socket located closest to where the cabling enters your home. Typically, this will be near the street-front. We also recommend testing other wall sockets throughout your property, as we’ve found that connecting to other outlets may reduce the performance of your service.
  • If you choose to relocate your telephone wall socket and require assistance, please contact your service provider or a registered cabling organisation for a quote.
  • We recommend positioning your Wi-Fi router/modem in the centre of your home or central to your internet-connected devices. This will help to ensure you receive the best connection possible.
  • When using Wi-Fi enabled devices, double check there’s nothing blocking your Wi-Fi router/modem, as this may interfere with the connection.
  • Try to avoid placing your Wi-Fi router/modem behind the TV or thick walls. This can affect your Wi-Fi connection speed levels. 
Check your cables
  • If there’s more than one connected telephone wall socket in your home this may significantly weaken the performance and stability of your service. To discuss improving your connection performance, please speak to your cabling organisation.
  • In the case of multiple connected telephone wall sockets, please ensure these are isolated from the main socket. This can help improve the performance of your FTTC service. Please speak to your service provider or a registered cabler if you need additional assistance.
  • Any previously installed ADSL filters or line splitters will need to be removed. If they remain connected, they will likely affect your service performance. For more information, please refer to our nbn™ Troubleshooting Guide below.
  • Keep in mind that some older homes may have time worn wiring that may also impact service performance.

Some existing services may be affected

The rollout of the nbn™ access network involves new technologies, which some existing devices may not be compatible with such as medical alarms, autodiallers or emergency call buttons. Contact your device provider to find out if your alarm or device will work when connected to the nbn™ access network, and what alternative solutions are available.

Make sure you also register your devices with nbn. Registering helps nbn identify premises where support may be needed to help minimise a break in service.

Landline phone calls using the nbn™ access network use Voice over Internet Protocol (VoIP) technology instead of the standard copper phone networks. This means audio signals get converted into digital data before being sent over the internet to other landline phones.

VoIP-compatible phones

  • VoIP-compatible phones let you make voice calls over the internet. Your telephone provider can tell you whether your existing landline phone will be VoIP-compatible and can also supply you with a new VoIP-compatible phone if necessary.
  • If you have a phone-only connection, your telephone provider will supply you with additional equipment so you can connect your VoIP-compatible phone to your nbn™ compatible Wi-Fi router/modem.

Switching a phone service can take a few days after ordering an nbn™ powered plan from a phone provider.

For more information regarding wait times, please speak to your phone provider.

nbn™ compatible wall outlets
  • If you have multiple telephones located within your premises that you would like to continue using, we recommend engaging with a registered cabler to assess and reconfigure your in-home wiring.
  • Alternatively, cordless phones can be connected to the back of your modem and used anywhere in the house without the need to change any wiring.

An end user’s experience, including the speeds actually achieved over the nbn™ broadband access network, depends on the nbn™ access network technology and configuration over which services are delivered to their premises, whether they are using the internet during the busy period, and some factors outside of nbn’s control (like their equipment quality, software, chosen broadband plan, signal reception, or how their provider designs its network).
Discuss your nbn™ set up with your phone and internet provider. They'll be able to provide you with more information on optimising your in-home setup.
