Compatibility Guide

This router requires an au 5G service plan. It supports Japanese 5G NR bands (n77/n78) and LTE bands. International use is not guaranteed. For wired connections, a 2.5GbE-capable LAN cable is recommended. Best performance is achieved with Wi-Fi 6 compatible devices.

Ideal Use Cases

  • Households in rental apartments where fiber optic installation is difficult
  • Users in 5G coverage areas seeking quick and easy high-speed internet
  • Teleworkers and online gamers who need stable connectivity
  • Families with multiple smartphones and tablets connecting simultaneously

Upgrade Considerations

Since this router relies on 5G signals, placement significantly affects speed. Position it near a window or in an area with strong reception. Outside 5G coverage, it will fall back to LTE, resulting in lower speeds. Be aware of data caps in your plan if you frequently use large amounts of data.
