The TP-Link Deco X55 2-pack is an AX3000 Wi-Fi 6 mesh system that replaces a single router with two matching units, giving seamless whole-home coverage of up to about 4,500 sq ft, which TP-Link rates for a typical 3-4 bedroom house. Each unit is dual-band, with up to 2402 Mbps on 5 GHz (160 MHz channels) and 574 Mbps on 2.4 GHz, and supports OFDMA and MU-MIMO so busy households with over 150 connected devices stay responsive. Every Deco has three Gigabit ports with WAN/LAN auto-sensing, so you can plug in a fibre ONT, a desktop PC or a smart TV, or link the units with a cable for wired (Ethernet) backhaul. Devices roam between units on a single network name, and TP-Link's AI-Driven Mesh learns your home to pick the best paths. Setup and management run through the Deco app, which also provides HomeShield security, parental controls, QoS by device and guest networks. In the box: two Deco X55 units, two power adapters, one Ethernet cable and a quick installation guide.
