The ASUS RT-BE90U sits at number nine in this guide. It is a tri-band Wi-Fi 7 (802.11be) router at £150.29, with 320 MHz channels, 4096-QAM, four ports that can be configured as WAN or LAN, and AiMesh support for extending coverage across the home. The first bullet on the listing promises "speed to 9400Mbps".

The specification fields on that same listing do not go that high. They give a data transfer rate of 5,764 Mbps and a maximum upstream data transfer rate of 5,764 Mbps, with LAN port bandwidth stated as 2,500 Mbps. So the 9,400 figure is the tri-band total rather than a rate any single connection is quoted at reaching. The ratings do not quite line up either: the listing quotes 47 ratings, while the histogram underneath it counts 100, 71 of them five-star. Everything on this page is taken from the Amazon listing for this router; none of it comes from testing we carried out ourselves.
