Frequently Asked Questions
Can I use just one Deco M4 unit, or do I need multiple?
A single Deco M4 unit covers up to 180m² and works as a standalone router. If your home is larger or has areas with weak signal, you can add additional Deco units at any time to extend coverage — they all work together as one seamless network.
Does the Deco M4 work with my Australian ISP?
Yes. The Deco M4 is compatible with all major Australian internet service providers including Telstra, Optus, TPG, Aussie Broadband, and others. It works with standard NBN modems and routers in both router and access point modes.
What is the difference between router mode and access point mode?
In router mode, the Deco M4 connects directly to your modem and manages your home network including DHCP and NAT. In access point mode, it connects to an existing router and extends Wi-Fi coverage without replacing your current network setup. Both modes are configured via the Deco app.
Can I mix Deco M4 units with other Deco models?
Yes. The Deco M4 is compatible with all other Deco models, so you can mix and match units to build or expand your mesh network as needed.
Does the Deco M4 support wired backhaul between units?
Yes. While Deco units connect wirelessly by default, you can use Ethernet cables between units for a wired backhaul connection, which provides faster and more reliable inter-unit speeds — particularly useful in larger homes or multi-storey installations.
How do I set up the Deco M4?
Download the free Deco app on iOS or Android and follow the step-by-step guided setup. Most users are up and running in under 10 minutes. No technical knowledge is required.
Installation Tip: For the best mesh performance in a multi-unit setup, position each Deco unit within a reasonable range of the next — not too close (overlapping coverage) and not too far (weak backhaul signal). A general guide is one unit per floor or one unit per 180m² of floor space.
