Okay, I understand that you are concerned about losing certain advanced features, such as MU-MIMO and OFDMA, when mixing different Deco Mesh models in your network. You are wondering if it is better to use the exact same Deco model for all nodes to ensure you get full access to the features you paid for.

When you mix different Deco models in one mesh network, not all features are guaranteed to be available—even if your main Deco supports them. Some features, like MU-MIMO/OFDMA, WPA3 encryption, IoT network, and Reboot Schedule, will only be available if all Deco units in your network support them. If you add a Deco model that does not support these features, they may disappear from your Deco app and cannot be configured, even if your main unit supports them.

On the other hand, features such as VPN Server/Client, Static Routing, Changing WAN MTU, and HomeShield (Parental Control) are available as long as the main Deco supports them, regardless of the other models in the network.

Key points to consider:
• If you want to keep access to advanced features like MU-MIMO/OFDMA, it is recommended to use the same Deco model (and ideally the same hardware version) for all units in your network.
• Mixing different models may result in losing the ability to configure certain features via the Deco app, even if they are technically still available on supported units.
• If you are missing a specific feature, it does not always mean it is completely unavailable—it may just be inaccessible for configuration in the app.

If you want to maximize your network's capabilities and ensure you have access to all the features you paid for, it is worth considering using identical Deco models throughout your mesh network. If you need further clarification or want to confirm feature availability for your specific setup, please contact TP-Link support.
