Single-unit mesh node

The Deco X20 is a Wi-Fi 6 mesh node sold as a single unit that can function as a router or access point. It targets homes up to 2,200 square feet where a single device can replace an older standalone router and extender combo. The Qualcomm quad-core CPU handles traffic for multiple simultaneous connections.

AX1800 dual-band limits

The node delivers 1,201 Mbps on the 5 GHz band and 574 Mbps on the 2.4 GHz band using 1024-QAM and OFDMA. Two Gigabit Ethernet ports serve as configurable WAN or LAN links, capping wired throughput at 1 Gbps. Transmit power follows FCC and CE limits, and the unit operates between 0 °C and 40 °C with up to 90 % humidity.

Upgrade from single-router setups

This unit replaces a traditional router plus separate extender by creating a unified mesh that supports seamless roaming and self-healing paths. Adding further Deco X20 nodes expands coverage without reconfiguration. The jump is worth it when dead zones persist despite a centrally placed legacy router.

Questions sur cet article

Should I choose the 1-pack Deco X20 or add more units for my home size?

The 1-pack covers up to 2,200 sq. ft. with a single unit; add more Deco X20 units to extend coverage beyond that area.

What does the AX1800 rating mean for everyday speeds on the 5 GHz and 2.4 GHz bands?

The AX1800 label combines 1201 Mbps on 5 GHz and 574 Mbps on 2.4 GHz; real-world throughput will be lower due to overhead and interference.

How do the two Gigabit Ethernet ports limit my wired backhaul or WAN connection?

Both ports are 1 Gbps LAN/WAN, so wired backhaul and ISP links are capped at 1 Gbps per port.
