MLO backhaul connection between nodes

[cniedzi]

Hi,

I've built mesh system as in the attached picture. Is it possible to get MLO backhaul connection between nodes or it is impossible by design?

Seems like no response on this. I had exactly the same question and could not find an answer anywhere.

response from Chat G..

Yes, MLO (Multi-Link Operation) backhaul between nodes is possible, but it depends on both hardware and software implementation by the router manufacturer. It is not impossible by design, but not all routers support it yet.

MLO Backhaul – How It Works​

MLO allows simultaneous data transmission across multiple bands (2.4 GHz, 5 GHz, and 6 GHz) to improve speed, reduce latency, and enhance reliability. For a mesh system, this means:

• Traditional backhaul: Uses a single band (typically 5 GHz or 6 GHz).
• MLO backhaul: Uses multiple bands at the same time for increased throughput and stability.

Is MLO Backhaul Supported?​

• Some Wi-Fi 7 mesh systems will support MLO for backhaul, but it's not guaranteed on all routers.
• Many early Wi-Fi 7 routers (like the Asus RT-BE6800) do not support MLO backhaul yet, as the feature is still rolling out.
• Firmware updates may enable it later, depending on vendor support.

Potential Limitations​

• Router/Node Support: Both the main router and mesh nodes must support MLO backhaul.
• No 6 GHz Band? If your router lacks 6 GHz (like the RT-BE6800), MLO backhaul would be limited to 2.4 GHz + 5 GHz, which is less ideal.
• Firmware Implementation: Even if the hardware allows it, the manufacturer needs to enable and optimize it via software.

Verdict​

Yes, MLO backhaul is possible and is a key feature of Wi-Fi 7, but not all routers currently support it. If you're looking for MLO-enabled mesh systems, check models like:

• TP-Link Deco BE95
• Asus ROG Rapture GT-BE98 (likely via future update)
• Netgear Orbi BE27000 (potential MLO support)

So I guess the answer NOW is no, maybe in the future? Only issue with the BE86U is it is dual band, they may only be working on MLO for tri band units...
