How to Mix Different TP-Link Deco Models for Optimal Mesh Network Performance

Mixing TP-Link Deco models is completely possible, but to achieve maximum performance, you need to understand main node priority, backhaul options, and feature limitations. This guide will walk you through the process step by step.

1️⃣ Main Deco Priority: Choose the Right Unit

The Main Deco determines your network’s performance and available features. Use the following hierarchy:

2️⃣ Feature Limitations When Mixing Models

3️⃣ Powerline Backhaul (Deco P7, P9, PX50)

Key rules for Powerline-capable Decos:

1. Set a Powerline Deco as the Main Deco.

2. Powerline only works between Deco units on the same electrical circuit.

3. Non-Powerline models will connect wirelessly.

 Tip: Use the most powerful Powerline Deco as Main for maximum stability.

4️⃣ Ethernet Backhaul: Maximize Performance

Ethernet backhaul is recommended when mixing old and new models:

• Connect nodes via Ethernet cables or a network switch.

• Nodes broadcast at full speed while maintaining connectivity.

• Wireless still works but won’t reduce performance.

5️⃣ Adding a New Deco to an Existing Network

Step-by-step upgrade:

1. Update the Deco App – Make sure it’s the latest version.

2. Add the new Deco as a satellite – Open the app, tap “+”, follow instructions.

3. Update firmware – Go to “More → Update Deco”.

4. Set new Deco as Main – Use “Set Main Deco” in the app and swap physical location if needed.

 This ensures minimal downtime and preserves existing settings.

6️⃣ Key Takeaways

• Always follow the Main Deco hierarchy.

• Use Ethernet backhaul for mixed-generation units.

• Powerline backhaul works best on the same electrical circuit.

• Keep app and firmware up-to-date.

• Features may temporarily disappear but can return with firmware updates.
