TP-Link Deco X55 AX3000 Whole-Home Mesh Wi-Fi 6 System (3-Pack)
Whole-Home Wi-Fi 6 Coverage for Large and Multi-Storey Homes
The TP-Link Deco X55 3-Pack delivers seamless Wi-Fi 6 coverage across your entire home — up to approximately 690m² — with no dead zones and no compromises. Whether you have a large single-storey home, a multi-level property, or a layout with thick walls and long corridors, three Deco X55 units work together as an intelligent mesh to keep every device connected at AX3000 speeds. Setup takes minutes via the Deco app, and the system manages itself from there.

Frequently Asked Questions
How much coverage does the Deco X55 3-Pack provide?
The 3-pack covers approximately 690m² in typical home environments. Actual coverage may vary depending on building materials, layout, and interference sources. Homes with thick concrete or brick walls may require units to be placed closer together.
Can I mix the Deco X55 with other Deco models?
Yes. The Deco X55 is compatible with other Deco models and can be combined within the same mesh network, all managed through the Deco app.
Do all three units need to be plugged into my modem?
No. Only one Deco unit connects to your modem or NBN gateway. The remaining units connect wirelessly (or via Ethernet backhaul) to form the mesh network.
What is the best placement for the three Deco units?
Place the primary unit near your modem, then position the other two units roughly halfway between the primary unit and the areas with the weakest signal. The Deco app includes a signal strength indicator to help you find the optimal placement.
Does the Deco X55 3-Pack work with NBN?
Yes. The Deco X55 is compatible with all Australian NBN connection types, including FTTP, FTTN, FTTB, FTTC, and HFC, when connected to your NBN modem or gateway.
Is wired backhaul supported?
Yes. Connecting Deco units via Ethernet cable provides the most stable and highest-performance backhaul connection between units, which is recommended for large homes or demanding network environments.
What is TP-Link HomeShield?
HomeShield is TP-Link’s built-in network security suite powered by Trend Micro. It provides real-time threat detection, IoT device protection, parental controls with content filtering, and network health reports. Basic features are free; advanced features require a HomeShield Pro subscription.
