TP-Link 4G+ AX1800 Whole Home Mesh WiFi 6 gateway

Deco X20-4G is a whole-home mesh gateway with a built-in 4G+ modem and Wi‑Fi 6, designed to provide internet access in locations without fixed broadband. Insert a SIM card to get online at a vacation home, farm, warehouse or any place where wired connections are impractical. The system combines TP‑Link Mesh technology, dual‑band Wi‑Fi and optional powerline links to extend stable coverage and improved network capacity across the entire property.

Advantages

Built-in 4G+ modem enables internet access via a SIM card where wired broadband is unavailable. Wi‑Fi 6 increases throughput and capacity for many devices, while TP‑Link Mesh technology offers seamless roaming, adaptive path selection and self‑healing to maintain stable connections. Powerline support helps bypass thick walls and ceilings by using the electrical circuit to link Deco units. Integrated IoT support (Wi‑Fi, Bluetooth and Zigbee) removes the need for separate smart hubs.

How to use

Recommendations

Place the primary Deco near a window or an exterior wall for better 4G signal reception. For best whole‑home coverage, distribute additional Deco units evenly, avoid placing them inside cabinets or behind large metal objects, and consider using powerline links where Wi‑Fi signals must cross thick walls or floors.
