A budget kit has less margin for error than an expensive one, which makes setup worth more here than anywhere else. Eight steps, in the order that matters.

The single highest-value setup step on a cheap mesh system is to link two of the nodes with a wire — Ethernet, coax or mains — because a budget system relays everything over the same band your devices are using and loses about half of it each time. Everything else on this page helps, and nothing else helps as much.
That is also why setup matters more on a cheap system than an expensive one. A tri-band system has a reserved lane for the nodes and so tolerates a mediocre layout; a dual-band three-pack does not, and the difference between a careless install and a careful one can be the whole reason someone concludes that cheap mesh does not work.
1. Wire any two nodes you can, before anything else
On nearly every current system this needs no settings at all: plug an Ethernet cable between the router node and a satellite and the system detects it and stops relaying over the air. If there is no cable route, look for a coax outlet in both rooms and use MoCA adapters; if there is no coax, try powerline, which is variable by house but still a wire. The full method is in Ethernet backhaul for mesh Wi-Fi.
2. Deal with your provider's box before you place anything
Two routers running two networks in one building is the most common self-inflicted problem in home Wi-Fi. Put the ISP gateway into bridge mode, or at minimum turn its Wi-Fi off, so the mesh system is the only thing handing out addresses and the only thing broadcasting. Replacing your ISP's router covers how that works per provider, and adding mesh to an existing router covers the case where the box has to stay.
3. Space the nodes for the link, not for the floor plan
eero's own guidance is a sensible rule for any brand: 20 to 30 feet between units, and no more than about 50 feet when the link is wireless. Place each node roughly halfway between the previous one and the area you are trying to cover — never in the dead zone itself, because a node can only pass on what it receives. Where to put mesh nodes has the room-by-room version.
4. Never daisy-chain a cheap system
If node three connects through node two rather than directly to the router, its traffic crosses the air twice more. On a dual-band system that leaves roughly a quarter of the original throughput. Arrange the nodes in a star around the router rather than a line down the house, and if the house shape forces a line, that is precisely the house that needs a wire.

5. Get the nodes out of cabinets, off floors and away from metal
Radio does not like being enclosed. Waist height or higher, out in the open, not inside a media cabinet, not behind a television, not on the floor next to a radiator. This costs nothing and routinely changes the signal in the next room more than a hardware upgrade would — where to put your router applies to every node, not just the first one.
6. Update the firmware on day one, then leave it on automatic
Cheap systems ship from the warehouse with old firmware more often than expensive ones, and early firmware on a budget platform is where the roaming and stability bugs live. Update before you judge the hardware. Then leave automatic updates on — our maintenance routine is the rest of that story.
7. Leave the defaults alone, with two exceptions
Band steering, channel selection and roaming thresholds are better left on automatic than tuned by hand on a budget system. The two exceptions worth making: if neighbors are dense, check what the 2.4 GHz channel has landed on, because the automatic choice is sometimes poor in an apartment building (how to check); and if you have smart-home devices that will only join 2.4 GHz, make sure the system lets them, which on some platforms means a temporary separate network name.
8. Measure before and after, in writing
One test per room, same device, same spot, written down — before the mesh system arrives and again after it is placed. It takes ten minutes, it is the only way to know whether the second node is earning its socket, and it tells you whether to return the kit or add to it. How to test Wi-Fi speed in each room is the method.
This usually backfires
Do not add a third node to fix a slow first node
If the speed is poor standing next to the router node, the problem is upstream of the mesh system — your plan, your modem or your provider — and extra nodes rebroadcast the same slow connection to more rooms. Internet fast but Wi-Fi slow separates those two cases in about five minutes.
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.

Common questions
How do I make a cheap mesh Wi-Fi system faster?+−
Wire two of the nodes together. A budget mesh system is usually dual-band, which means it relays your traffic over the same band your devices use and delivers roughly half of it at the far node. An Ethernet cable, a pair of MoCA adapters over existing coax or a powerline pair removes that penalty for far less than the price of a better system.
How far apart should cheap mesh nodes be?+−
About 20 to 30 feet, and no more than roughly 50 feet when the link between them is wireless — eero publishes those figures and they are a reasonable rule for any brand. Place each node between the router and the weak area rather than in the weak area, because a node can only rebroadcast the signal it receives.
Should I turn off my ISP router's Wi-Fi when I install mesh?+−
Yes. Two sets of radios in one building compete for the same airtime, and two routers handing out addresses creates double NAT, which breaks port forwarding and upsets some games and VPNs. Bridge mode is better than switching the radios off, where your provider offers it.
Can you daisy-chain mesh nodes?+−
Most systems allow it and you should avoid it on a cheap one. Each extra wireless hop halves throughput again, so a node relaying through another node can end up with about a quarter of what the router node has. Arrange nodes in a star around the router, or wire the far one.
