How Many Deco Units Do I Need for My Deco Mesh Network?

How many Deco units your network needs depends on two things: the Deco model you have and the type of backhaul connection you're using. Whether you're planning a new Deco mesh network or expanding an existing one, this guide covers recommended unit counts for both Wi-Fi and Ethernet backhaul setups.

Key Takeaways

• For most Deco models using Wi-Fi or PLC backhaul, TP-Link recommends up to six units in a single Deco mesh network.
• For select Wi-Fi 6, 6E, and 7 models (such as the Deco X68, X90, XE75, BE95, and BE85), more than six units may be added to a Wi-Fi or PLC backhaul network if needed.
• For Deco mesh networks using Ethernet backhaul, or a hybrid of Ethernet and Wi-Fi backhaul, there is theoretically no unit limit. However, TP-Link recommends up to six units for Wi-Fi 5 models (such as the Deco E4, M4, and P9) to maintain a smooth Deco app experience.
• Adding more Deco units does not always improve wireless throughput or stability. If there are no dead zones, additional units may not be necessary.
• Actual performance can vary based on home layout, physical obstacles, and the distance between Deco units.

Deco Units for Wi-Fi and PLC Backhaul Networks

For most Deco models, TP-Link recommends using up to six units in a single Deco mesh network. This applies to networks running on Wi-Fi or PLC backhaul.

If you have a Wi-Fi 6, 6E, or 7 model, such as the Deco X68, X90, XE75, BE95, BE85, or similar, you can add more than six Deco units to your network if your coverage needs call for it.

Deco Units for Ethernet Backhaul and Hybrid Networks

For Deco mesh networks using Ethernet backhaul, or a hybrid setup combining Ethernet and Wi-Fi backhaul, there is theoretically no limit on the number of units you can add.

That said, for Wi-Fi 5 models like the Deco E4, M4, and P9, TP-Link recommends staying at six units or fewer per network to keep the Deco app running smoothly. For Wi-Fi 6 and 6E models on Ethernet backhaul, you can add more units as needed.

Tips

• Wireless throughput and stability do not always improve as you add more Deco units. If your current setup has no dead zones, more units may not be necessary.
• The recommendations above are for reference only. Actual performance can vary depending on your home layout, obstacles, and the distances between Deco units.
• For a personalized recommendation, contact TP-Link support with your house layout plan for more accurate guidance on how many units to add.
