Getting Wi-Fi through thick walls

In an old brick or stone house, a mesh system’s wireless link between units is the weak point: the signal that has to pass through the walls is the one that carries all the traffic.

Every system on this page supports wired backhaul, so you can link the units with Ethernet and take the walls out of the equation. Where cabling isn’t possible, favor tri-band kits, which keep a separate radio for the unit-to-unit link, and plan for more units placed closer together.

Most of these units also work well wirelessly in normal homes. See all mesh Wi-Fi systems or routers for large homes.

Frequently asked questions

Why do thick walls kill Wi-Fi?

Brick, concrete, stone, plaster on metal lath and foil-backed insulation absorb or block radio signals. 5 GHz and 6 GHz suffer most, which is where the fast speeds are.

What is wired backhaul?

Connecting your mesh units to each other with Ethernet cable instead of Wi-Fi. The link no longer has to pass through the walls, so every unit gets full speed.

I have no Ethernet cables. What can I do?

Powerline adapters or MoCA adapters (over coax TV cable) can carry the link. Otherwise, place units closer together, ideally one per room that has a thick wall between it and the next.
