TP-Link Deco X90 AX6600 Mesh System

The TP-Link Deco X90 is a tri-band Wi-Fi 6 mesh system sold as a two-pack. It replaces a traditional router and range extenders to deliver whole-home coverage up to 6000 square feet. The system supports up to 200 connected devices and uses AI-driven mesh technology to optimise traffic paths. It is suited for households that want seamless roaming without managing separate network names.

Tri-band Wi-Fi 6 practical limits

The system operates on one 2.4 GHz band and two 5 GHz bands with a combined data rate of 6600 Mbps. Real-world throughput is lower due to overhead, interference and client capabilities. Each unit provides one 2.5 Gbps Ethernet port and one Gigabit port for wired backhaul or device connections. The 2.4 GHz band is limited to 574 Mbps and the second 5 GHz band to 1201 Mbps.

Compatibility checks before ordering

Verify that your internet modem has an available Ethernet port for the primary Deco unit. Ensure you have power outlets near the desired unit locations. The Deco app requires a smartphone or tablet for setup and management. Wired backhaul needs Ethernet cabling between units. HomeShield Pro features require a subscription after the trial period.

How fast is the 2.5 Gbps Ethernet port in real use?

The 2.5 Gbps port caps wired backhaul or a single device at 2.5 Gbps; the second port on each unit is limited to 1 Gbps.
