High speed NBN modem requirements

Our NBN Superfast & NBN Ultrafast plans are currently supplied on a “BYO modem” basis, which means that you’ll need to supply your own modem.

Most modems in use today are technically capable of supporting speeds of approximately:

  • Up to 300Mbps over WiFi
  • Up to 600Mbps over Ethernet

Of course, actual speeds achieved will vary due to a number of factors such as technology type, modem capability, plan choice and internet traffic demand.

Faster speeds may be achieved if you choose to purchase a newer, high-end modem. Mesh networking solutions, where several devices broadcast WiFi throughout a premises, are recommended for NBN Ultrafast services in particular.

In short, your modem must support or feature:

  • PPPoE connection types
  • VLAN tagging
  • Gigabit Ethernet ports
  • AC WiFi or WiFi 6 (for WiFi connections)

Modems that do not support PPPoE or VLAN tagging cannot connect to our NBN services. If you choose to use an older modem that does not feature Gigabit Ethernet ports or AC WiFi/WiFi 6, your connection may be slower according to the constraints of your older hardware. We recommend using devices connected via Ethernet cable instead of WiFi to get the best possible experience.

Compatible modems

The following modems have been tested by our team. There may be additional models on the market that have not yet been tested by us. If your modem is not listed here, please contact the manufacturer for more information.

Note that all modems listed below (including those marked with a cross) are capable of achieving the estimated Typical Evening Speed~ of the NBN Superfast and NBN Ultrafast plans, which is 200Mbps.

^While the NBN Ultrafast Plan has a maximum theoretical off-peak download speed of 500Mbps on NBN HFC and 990Mbps on NBN FTTP, you will typically experience significantly slower speeds than this due to a range of factors, regardless of which modem you use. You should refer to the Typical Evening Speed as a more accurate estimate of likely experience. 

Incompatible modems

The following modems have been tested by our team and will not work with our high speed NBN plans.

  • Google Nest WiFi – does not support VLAN tagging
  • Amazon eero - does not support PPPoE or VLAN tagging


~Typical Evening Speeds are subject to change and are measured 7pm-11pm. Speeds are not guaranteed and may vary. The NBN Superfast and NBN Ultrafast Plans are new plans, and therefore the TES stated here is currently based on an estimate. iiNet will revise the TES once it has collected enough data on the speed performance of these plans.
