Best mesh for thick walls
The short answer
Thick walls are beaten by putting a box on the other side of them, ideally joined by a cable — not by a bigger router.
For this one job we'd pick the NETGEAR Orbi. Its overall WiFiXpert Index score is 79/100 — which is not the same thing as being top of the overall table, and doesn't change it.

Why each one landed where it did
eero mesh
- Coverage: 8/10 — Extra units are cheap and easy to add, which is how coverage problems get solved.
- Wired backhaul support: 8/10 — Wired backhaul is supported and needs no special setting.
Ubiquiti UniFi
- Coverage: 9/10 — Coverage is limited only by how many access points you cable in.
- Wired backhaul support: 10/10 — Designed around wired links from the ground up.
TP-Link Deco
- Coverage: 8/10 — Three-packs are affordable, which is usually what fixes coverage.
- Wired backhaul support: 8/10 — Wired backhaul supported across the range.
What we're assuming
- We do not calculate radio loss through your specific walls. We weight reach and the ability to wire boxes together, because that is what fixes solid walls in practice.
- Try the free fixes first — moving the router, or moving one box — before buying anything. Common problems and free fixes.
