What factors can affect the speed of my nbn™ internet connection?

When connected on a service with (for example) a 100 Mbps interface speed, you should not expect that everything that you download from the Internet will be received by you at 100 Mbps!

There are many factors that will affect your actual speeds (what you will see on a speed test). These include:

  • The type and source of the content being downloaded; i.e. the website, server and protocols in use
  • The performance of infrastructure not operated by Aussie Broadband; this includes the parts of the nbn™ network or wholesale infrastructure
  • How your device is connecting to the internet; if using WiFi you may experience slower speeds than if you are connected via an Ethernet cable
  • Any service impacting faults that have or have not been reported to Aussie Broadband
  • Any limitations of the end user’s local network that may or may not have been reported to Aussie Broadband; this includes, but is not limited to, data cabling, bridged networks and number of locally connected devices
  • The technical limitations of your nbn™ connection type;
    • FTTB/N customers will be affected by their speed potential (see below)
    • Fixed Wireless customers may be affected by cell congestion
    • HFC customers may be affected by network segmentation

    For Home Ultrafast customers:
    We currently do not have any data on typical evening speeds, as soon as we do, we will update our FAQ with that information. There are a few factors that can impact users on fast speed plans.

    • Hardware issues: Many routers/modems are not designed for top speeds over WiFi connections. To obtain the most out of your high speed connection, we recommend using an ethernet cable for your devices. If that is not possible, our recommended router is Google’s Nest. Speak to our sales team if you’d like to purchase the from us.
    • Typical evening speeds are dependent on CVC capacity. We are currently estimating them to be around 215Mbps. This measure is based on a lower speed tier and will be updated when more data is collected.
    • This plan is available to all FTTP and a limited number of HFC customers.

    For FTTN and FTTB customers there is a theoretical maximum speed known as your speed potential. This is determined by several factors as outlined below:

    • Distance to the node
    • Quality of the copper path including internal cabling
    • Number of phone points at your premises
    • Other devices connected to your phone points (ie. back to base alarms)
    • Legacy copper services still active in your area ie ADSL, Fixed Phones, etc. (Co-existence)

    Upon connection of a new FTTN/B service we will notify customers via email of their current speed potential and offer for them to adjust their plan without financial penalty if maximum speeds are unobtainable on their selected speed tier.
