Mercusys MR47BE BE9300 Tri-Band Wifi 7 Router

The MERCUSYS MR47BE is the router at the top of this guide. It is a tri-band Wi-Fi 7 model at £149.52 with a 4.3-star average from 10,093 ratings, four 2.5 Gbps ports, and support for 320 MHz channels, 4K-QAM, MLO and the 6 GHz band. On paper it looks fast; the question is which of its numbers a single device can actually reach.

The big figure is the one in the name. The MR47BE is sold as BE9300 and "Blazing-Fast 9.3Gbps", but the same listing states a maximum upstream data transfer rate of 3,000 Mbps and a LAN port bandwidth of 2,500 Mbps. The 9.3 Gbps is the three bands added together, so one device tops out at 3,000 Mbps rather than 9.3 Gbps. The four 2.5 Gbps ports come to 10 Gbps of wired capacity in total, yet each port is listed at 2,500 Mbps, so nothing wired runs above 2.5 Gbps. One buyer on a 1 Gbps full-fibre line reports Wi-Fi rising from roughly 520 Mbps to 930-950 Mbps, which is the limit of that connection, not of the router's headline. Another five-star review praises "WiFi 6" on a router sold on Wi-Fi 7. Coverage is the vaguest part of the listing: "Extensive Wireless Coverage", with no square-metre figure attached. Everything on this page comes from the Amazon listing for this router, not from our own testing.
