How to boost Wi-Fi signal at home and in the office

Wi-Fi is radio, and everything a building is made of interferes: reinforced concrete walls eat the signal most, followed by mirrors, metal doors and heated floors. Few routers push confidently through two concrete walls, and practically none through three.

The second reason is the neighbors. In an apartment block, dozens of networks share the same 2.4 GHz channels at once. Speed drops not because the signal is weak, but because the air is busy.

Placement first: the router belongs in the center of the home, up high, not in a cabinet or behind the TV. Every meter from the center toward a corner costs coverage in the opposite corner.

Then the channel: switch automatic channel selection to a specific free one (1, 6 or 11 for 2.4 GHz). A free analyzer app shows channel congestion. And check the band: if your devices support 5 GHz, move them there — it is faster and less crowded.

A repeater catches the router's signal and passes it on — but halves the speed and adds latency. Fine for a TV or a camera in a far room; annoying for work and games.

The classic mistake is placing the repeater where the signal is already poor: it amplifies and relays a poor signal. It belongs halfway, where the router's signal is still solid.

What solves the problem radically is not amplification but a second distribution point: a network cable runs to the far part of the building and an access point sits on it. Cable loses no speed to obstacles, and the AP serves full Wi-Fi in its zone.

In offices this is the only right way: PoE-powered ceiling access points, one network with seamless roaming — the phone switches to the nearest AP by itself, and a call survives the walk between rooms.

Mesh is several nodes that build one network themselves and hand devices from node to node. It installs in an evening without cables, looks neat and clearly beats a repeater — the nodes talk over a dedicated radio link.

An honest caveat: radio mesh still trails wired access points. The ideal scheme is mesh nodes linked by cable (Ethernet backhaul): mesh simplicity plus wire speed.

An apartment up to three rooms — a well-placed modern router, one mesh node if needed. A large apartment or house — a 2–3 node mesh, ideally cabled between floors. An office — wired PoE access points with a controller, calculated from the floor plan.
