Overview

The TP-Link Deco X90 is a tri-band mesh WiFi 6 system engineered to deliver comprehensive wireless coverage without the dead zones and speed drops that plague single-router setups. Operating across three bands — 2.4 GHz at 574 Mbps, a primary 5 GHz band at 4804 Mbps, and a secondary 5 GHz band at 1201 Mbps — it achieves combined theoretical speeds of up to 6600 Mbps. The key advantage of this tri-band architecture is the ability to reserve one 5 GHz band exclusively for backhaul communication between Deco units, ensuring that your devices get the full speed of the remaining bands without contention.

TP-Link's AI-driven mesh technology sets the Deco X90 apart from basic mesh systems by continuously analyzing network conditions and automatically adjusting client steering, band selection, and routing paths. The smart antenna system further enhances performance by dynamically focusing wireless signals toward active devices rather than radiating equally in all directions. Each unit includes a 2.5 Gbps Ethernet port alongside a standard Gigabit port, supporting wired backhaul for those who want the absolute best inter-node performance. This renewed unit has been inspected and tested to meet functional standards, making it an accessible entry point into high-performance mesh networking.

Pros & Cons

👍 Pros

  • Tri-band design with dedicated wireless backhaul prevents speed loss between mesh nodes
  • AI-driven mesh technology automatically optimizes routing and band steering for each device
  • 2.5 Gbps Ethernet port on each unit supports wired backhaul and high-speed wired connections
  • Combined speeds up to 6600 Mbps across all three bands handle heavy network loads
  • Smart antenna technology focuses signal toward connected devices for stronger, more reliable coverage

👎 Cons

  • Only two Ethernet ports per unit limits the number of devices you can hardwire without a switch
  • Renewed condition means potential cosmetic imperfections and typically a shorter warranty than new
  • Large physical size of each Deco X90 unit compared to some competing mesh systems
  • No WiFi 6E support, which newer mesh systems now offer for even faster speeds on the 6 GHz band

Frequently Asked Questions

The Deco X90 uses AI-driven mesh technology that intelligently learns your network environment and automatically optimizes routing, band selection, and client placement. It also features smart antennas that focus signal strength toward connected devices rather than broadcasting uniformly.
The three bands — one 2.4 GHz and two separate 5 GHz bands — allow the Deco X90 to dedicate one 5 GHz band as a wireless backhaul link between mesh units while keeping the other bands free for your devices. This prevents the common mesh problem of halved speeds at each hop.
Yes. Each Deco X90 unit has Ethernet ports, including a 2.5 Gbps port, that support wired Ethernet backhaul. This provides the most stable and fastest connection between units if you have Ethernet cabling available.
Renewed means the unit has been inspected, tested, and restored to working condition by a qualified refurbisher. It may show minor cosmetic wear but should function like new.
Each unit has two Ethernet ports: one 2.5 Gbps port and one standard Gigabit port, allowing you to hardwire devices like gaming consoles or desktop computers.
