Ethernet Backhaul for Mesh Wi-Fi: My Speed Test
I connected a Deco satellite with Ethernet and compared it with its weak wireless backhaul. The result explains why a cable between mesh units can matter more than buying a faster internet plan.
The main takeaway
My wired-backhaul demonstration was over five times faster. The lesson is to fix the connection between nodes when that's the bottleneck, rather than expect wireless coverage alone to solve it.

What wired backhaul means
Backhaul is the route carrying traffic between a mesh satellite and the main network. Your phone can have a good connection to the satellite while that satellite has a poor route back. In this March 2023 video I replaced that wireless hop with an Ethernet connection. It's a different job from wiring a laptop directly: the benefit can reach wireless devices using that satellite too.
The connection change I watched in the app
Before plugging in the cable, my Deco app showed a weak Wi-Fi connection between units. After connecting Ethernet and waiting for detection, the indicator changed to a wired connection. That confirmation is important. Don't assume a cable has become the active backhaul simply because it is plugged in. Follow the model's required wiring topology and check the app or management interface.
What the test actually showed
The new speed demonstration was over five times faster than the earlier wireless result in my setup. That is evidence that the backhaul had been holding this connection back. It isn't a promise that every mesh network improves by that amount, especially if the original wireless link was already strong or a slower port limits the wired path. Repeat the test using the same device and location so the comparison stays useful.
Options when the house lacks Ethernet
I also discussed MoCA adapters as a way to use compatible existing coax to supply a wired route. Those need a suitable coax path, correct installation and power at the endpoints. If wiring isn't practical, placing the node where it has a better upstream signal is still worth trying. The original video includes a VPN sponsor segment; that segment isn't the cause of the backhaul improvement or a prerequisite for the setup.

Will Ethernet backhaul make every mesh system five times faster?
No. That was the result of my particular weak-wireless-link comparison.
Can Wi-Fi clients benefit from wired backhaul?
Yes. Their traffic can use the improved wired route from the satellite back to the network.
