Overview

The TP-Link Archer BE400 is a dual-band router that carries Wi-Fi 7 into more approachable territory. Its calling card is Multi-Link Operation, which transfers data across frequency bands at once for higher throughput, lower latency, and steadier connections. Add Multi-RUs and 4K-QAM, and the BE400 is built to reward the latest laptops and phones. TP-Link rates it as a BE6500 device, meaning up to 5764 Mbps on the 5GHz band and 688 Mbps on 2.4GHz with six streams. It suits remote workers, gamers, and students who already own Wi-Fi 7 gear and want the newer standard without stepping up to a tri-band model.

On the hardware side, a quad-core CPU anchors the router, and six high-performance antennas with Beamforming are meant to hold reliable signal for as many as 90 devices across up to 2,400 sq. ft. Wired options are where it stands out for the class: dual 2.5 Gbps ports plus three gigabit LAN jacks and USB 3.0. Setup runs through the Tether app or a web interface, and EasyMesh lets you pair it with compatible units for whole-home coverage. HomeShield, robust parental controls, and Private IoT protection round out the security story, and TP-Link notes it is built under CISA's Secure-by-Design pledge. This listing ships as a pack of six.
