TP-Link Deco M4 AC1200 Whole Home Mesh Wi-Fi System

The TP-Link Deco M4 is an AC1200 dual-band mesh WiFi unit, built on the older but still capable Wi-Fi 5 (802.11ac Wave 2) standard, and sold individually as a 1-pack for smaller homes or as an add-on to an existing Deco M4 system.

Dual-Band Speed And Mesh Coverage

It delivers combined wireless speeds up to 1167 Mbps 867 Mbps on the 5GHz band and 300 Mbps on the 2.4GHz band — using 2×2 MU-MIMO technology to handle multiple devices at once, supporting up to 100 connected devices. TP-Link Mesh Technology includes Auto Path Selection, Self-Healing, AP Steering, Band Steering, and Beamforming to keep the network stable and automatically route traffic through the best-performing unit as more Decos are added.

Ports, Security And Setup

Each unit includes 2 Gigabit Ethernet ports (WAN/LAN auto-sensing) for wired connections, and can be set up in Router or Access Point mode depending on your setup. It supports optional Ethernet backhaul between units, a guest network, parental controls, QoS, and an SPI firewall with blacklist-based access control. It’s compatible with every other Deco model, so coverage can be expanded later just by adding more units, and setup and management run through the TP-Link Deco app.
