Key Features

  • Wi-Fi 6E support: Uses the 6GHz band for less interference and more stable connections
  • Tri-band 12-stream: Simultaneous operation on 2.4GHz (1147 Mbps), 5GHz (4803 Mbps), and 6GHz (4803 Mbps)
  • 10Gbps wired LAN port: Sufficient bandwidth for fiber internet and high-speed NAS
  • Eco packaging: Environmentally friendly simplified packaging
  • Broad device compatibility: Tested with latest smartphones and game consoles

Compatibility Guide

This router delivers maximum performance with Wi-Fi 6E compatible devices. The 6GHz band is only available on supported devices (iPhone 17 series, select Android flagships, latest PCs). The 5GHz and 2.4GHz bands remain compatible with legacy Wi-Fi 5/6 devices. The 10Gbps port is ideal for 10Gbps-capable NAS or PCs, but works fine with 1Gbps equipment.

Ideal Setup

  • Creators and NAS users who transfer large files frequently
  • Gamers who need high-speed connections for multiple devices simultaneously
  • eSports players who want to minimize latency using the 6GHz band
  • Can be used as a mesh network parent (child units sold separately)

Upgrade Considerations

To fully benefit from the 6GHz band, you need compatible client devices. The 10Gbps port requires matching switches or NAS to utilize its full speed. This model is an Amazon.co.jp exclusive, so purchase is limited to Amazon.
