Mesh Wi-Fi or wired access points?
Mesh is fine for smaller, open homes where the units can see each other clearly. Wired access points are better in larger homes, multi-level homes and homes with plaster, brick or foil-backed insulation, because every wireless hop costs throughput and adds latency.
When mesh is the right call
Under roughly 2,000 square feet on one or two open levels, with no practical way to run cable. Two or three nodes placed in the open will cover it well.
When wired wins
Larger homes, long narrow floorplans, three levels, detached structures, or dense construction. Each access point gets full backhaul speed, roaming between them is cleaner, and performance does not degrade as you add coverage.
Homes with many devices — cameras, TVs, tablets, smart home gear — also benefit, because wiring the stationary equipment frees up airtime for everything else.
The middle path
You do not need a cable to every access point. Wiring even one additional location, centrally placed, changes the shape of coverage more than adding two more wireless nodes.
