Wi-Fi 7 router for high-density homes

The Archer BE400 is a dual-band Wi-Fi 7 router built for households that run many devices at once. It supports up to 90 concurrent connections and covers up to 2400 sq ft, making it suited for families streaming 4K or 8K video, gaming online or using VR and AR applications. A quad-core processor handles the traffic load without bottlenecking the wireless throughput.

Dual 2.5 Gbps ports and USB 3.0 for wired

One 2.5 Gbps WAN/LAN port and one 2.5 Gbps LAN port let you connect a multi-gig internet line and a high-speed NAS or desktop directly. Three additional 1 Gbps LAN ports serve other wired devices such as consoles, printers or access points. The USB 3.0 port adds network storage or printer sharing without extra hardware.

Wi-Fi 7 throughput ceiling and client dependence

Maximum wireless throughput reaches 6452 Mbps using 4K-QAM, Multi-Link Operation and Multi-RUs across the 2.5 GHz and 5 GHz bands. Real-world speed depends on client devices that also support Wi-Fi 7 and on environmental interference. The router is EasyMesh compatible for whole-home expansion, but mesh performance will vary with node placement and backhaul quality.
