Plug a cable between two mesh nodes and the halving stops. It is the single biggest improvement available to a mesh network, and on most systems it needs no settings at all.

Run an Ethernet cable from a port on your main mesh unit to a port on a satellite, and the satellite stops relaying over the air. The usual halving of speed at the far node disappears, and on Deco, eero and ASUS systems there is no setting to change — the system detects the wire and uses it.
What backhaul is and why wiring it matters so much
A mesh satellite has to receive your data and then send it on again. That uses the air twice for one delivery, so on a dual-band system the far node passes along roughly half of what it receives — and a node relaying through another node halves it again. A tri-band system reduces the penalty by giving the nodes their own band. A cable removes it completely.
That is why the order of value in a mesh purchase is node count, then backhaul, then everything else, and why a cheap wired system beats an expensive wireless one. The full mechanism is on backhaul explained, and does mesh Wi-Fi slow your internet covers the numbers.

How to set it up
The physical job is the same on every system: a cable from any LAN port on the main unit to any LAN port on the satellite. Not the WAN port on the satellite — that port is for the connection coming from your modem, and on most systems using it will either do nothing or create a conflict.
TP-Link Deco. Plug the cable in and the Deco switches to the wired path automatically. TP-Link's own support material documents Ethernet backhaul as supported across the Deco range, and the app shows the connection type per node so you can confirm it took.
eero. Also automatic. With five ports on a Pro 7 there is no shortage of sockets, and the app reports each eero as wired or wireless.
ASUS AiMesh. Automatic by default, with the option to force a wired or wireless backhaul per node if you want to override the decision.
Netgear Orbi. Plug satellite LAN to router LAN; the Orbi app reports the backhaul state.
Verify it worked rather than assuming. Check the app for the per-node connection type, then run a speed test standing next to the wired satellite: it should now be close to what you get next to the main unit, rather than roughly half. The room-by-room method is the reliable way to measure the before and after.
This usually backfires
Do not daisy-chain a cable and a second router
Two mistakes cause almost every failed wired backhaul. The first is plugging the cable into the satellite's internet or WAN port instead of a LAN port. The second is leaving a switch or an old router in the path with DHCP still enabled, which puts a second network inside your network and produces a loop or double NAT. Use a plain unmanaged switch if you need one, and put any old router into access-point or bridge mode first — adding mesh to an existing router covers that properly.
What cable, and does the category matter
Cat 5e carries gigabit over any run length you will find in a house, and Cat 6 carries 2.5 Gbps and 10 Gbps over normal domestic distances. If you are buying new cable, buy Cat 6 — the price difference is trivial and it matches the 2.5 Gbps ports on current hardware. If you already have Cat 5e in the walls, use it; it is almost certainly not your bottleneck.
Flat cable along a baseboard, a short run through a doorway, or an existing telephone or television chase are all legitimate routes. If your plan is above a gigabit and you want the ports to match, multi-gig ports explained covers what 2.5 Gbps and 10 Gbps actually buy you.
If you genuinely cannot run a cable
You have two wired options that need no new cable at all:
MoCA over coax. Most US houses have coaxial outlets behind the televisions, which is often exactly where a mesh node wants to be. Two adapters turn any pair of them into a shielded gigabit-class Ethernet link that the mesh system treats as a cable — how MoCA works.
If no wire of any kind is possible, pay for a tri-band system with a dedicated backhaul band and place the nodes carefully — 20 to 30 feet apart, never in the dead zone. Mesh systems with the most Ethernet ports is the roundup for people planning to wire later, and node placement covers the wireless case.
How we picked
We do not run a test lab. Rankings here are built from the manufacturers' published specifications, measurements taken by independent outlets that do have labs, and the structural reasoning on this site about what a given house or job actually needs. Every product was checked as currently sold before it was included. Where a figure appears it is attributed and linked in Sources; where we have no basis for a claim, it is left out. Our methodology sets out exactly what we will and will not assert.

eero Pro 7Five Ethernet ports on every unit including a 10 Gbps WAN, and the software detects a wired node and switches to it with no setting to find.
TP-Link Deco X55Three nodes with three gigabit ports each. Wired, this dual-band system beats an unwired tri-band one that costs twice as much — which is the whole argument of this page.
goCoax MA2500DMoCA 2.5 in the 2.5 Gbps class over the coax already in the walls. It presents as Ethernet to the mesh node, so the system treats it as a wired backhaul.
TP-Link TL-PA9020P KITAV2000-rated powerline with two gigabit ports per adapter. Throughput depends entirely on your house wiring, but even a mediocre result usually beats a long wireless hop.

What it gets right
+Five Ethernet ports per unit is unusually generous, and it makes wired backhaul easy in a house with any cabling at all
+The 6 GHz band gives the nodes a fast, uncongested lane to talk to each other on
+Setup and node placement guidance in the app are the least frustrating of any system in this category
+Acts as a Thread, Matter and Zigbee hub, which can replace a separate smart-home bridge
What to watch for
−Some network controls people expect are behind eero's optional subscription
−Tri-band, not quad-band — a very large house on a multi-gig plan may prefer more radio capacity
−Amazon account linkage is part of the experience whether you want it or not

Common questions
What is Ethernet backhaul on a mesh Wi-Fi system?+−
It is a cable between two mesh units that carries the traffic normally relayed over the air. Because the satellite no longer has to receive and retransmit wirelessly, the usual halving of speed at the far node disappears and you get effectively full throughput there.
How do I set up Ethernet backhaul on a mesh system?+−
Run a cable from any LAN port on the main unit to any LAN port on the satellite — not the satellite's WAN or internet port. On Deco, eero, ASUS AiMesh and Orbi the system detects the wire and switches to it automatically; the app will show each node as wired or wireless so you can confirm it took.
Is Ethernet backhaul better than a tri-band mesh?+−
Yes. A dedicated backhaul band reduces the wireless penalty; a cable removes it. That is why a cheap dual-band system wired with Ethernet usually beats a more expensive tri-band one running wirelessly — and why it is worth checking for a cable route before you pay the tri-band premium.
Can I use MoCA or powerline as mesh backhaul?+−
Yes — both present as Ethernet to the mesh node, so the system treats them as a wired backhaul. MoCA over existing coax is the better of the two and gets close to a real cable; powerline varies with your house wiring but still usually beats a long wireless hop. Buy either with a returns policy.
