Mesh router TP-Link AC1200 Dual-band Wi-Fi 5

Deco M4 is a whole-home mesh Wi‑Fi system that provides AC1200 dual-band wireless coverage for homes up to 180 square metres. Using TP‑Link Mesh technology, multiple Deco units work together to create a single unified network with seamless roaming and improved stability. The system supports both wireless connections and optional Ethernet backhaul, and can be expanded by adding additional Deco units.

Advantages

Deco M4 eliminates Wi‑Fi dead zones and delivers faster network speeds with 802.11ac technology, supporting up to 100 connected devices. It offers seamless roaming under one Wi‑Fi name so devices automatically switch to the strongest unit as you move through the home. The unit also supports two operating modes—router and access point—allowing flexible deployment to match different network needs.
