TP-Link Archer BE400

Manufacturer: TP-Link

The TP-Link Archer BE400 is a dual-band router designed to bring Wi-Fi 7 connectivity to home and small-office networks. It supports multiple wireless generations — from Wi-Fi 4 through to Wi-Fi 7 (802.11be) — allowing it to communicate with a wide range of client devices. Six external antennas contribute to its signal distribution, and the unit can also participate in a mesh Wi-Fi setup for broader coverage across larger spaces.

On the technical side, the Archer BE400 delivers a combined wireless throughput of 5764 Mb/s and includes MU-MIMO and beamforming to help manage simultaneous connections more efficiently. Security is well covered, with WPA2 and WPA3 support, SPI intrusion protection, DoS protection, MAC address filtering, URL filtering, and parental controls all present. The router also supports IPv6, VLAN tagging, Inter-VLAN routing, dynamic and static routing, QoS, and UPnP, alongside a USB port with external memory slot support and a dedicated smartphone app for management.

Pros
  • Supports Wi-Fi 7 (802.11be) alongside Wi-Fi 4, 5, and 6, making it compatible with a wide range of wireless devices
  • Comprehensive security suite includes SPI intrusion protection, DoS protection, WPA3, MAC filtering, URL filtering, port filtering, and parental controls all in one device
  • Mesh Wi-Fi support allows the router to be expanded into a wider coverage network with compatible units
  • MU-MIMO and beamforming help distribute wireless signal more efficiently across multiple connected devices simultaneously
  • VLAN tagging with Inter-VLAN routing provides meaningful network segmentation options for users who need to separate traffic
  • Supports Matter, making it compatible with a growing ecosystem of smart home devices
Cons
  • Only a single USB port is available, limiting simultaneous external device connections
  • The one-year warranty period is relatively short for a networking device intended for long-term home use
  • Antennas are fixed and non-removable, so users cannot upgrade or replace them if signal output degrades
  • Not DLNA-certified, which limits its usefulness for users who rely on media streaming to DLNA-compatible devices
  • Dual-band configuration means there is no dedicated third band, which can affect performance when many devices are connected at once
  • No outdoor capability, restricting installation to indoor environments only
Who is this for?

This router is a solid fit for households or small offices that want to future-proof their network with Wi-Fi 7 support, particularly those already investing in newer client devices capable of taking advantage of the latest wireless standard. Its mesh Wi-Fi compatibility makes it well-suited for users looking to extend coverage across a multi-room environment without running additional cabling. The broad security toolkit — covering WPA3, SPI protection, parental controls, and traffic filtering — also makes it a practical choice for users who need granular control over network access, such as families or small teams managing shared internet connections. Those who work with segmented networks will appreciate the VLAN tagging and Inter-VLAN routing capabilities.

Who is this NOT for?

Users who need to cover outdoor spaces will find this router unsuitable, as it has no outdoor capability and is strictly designed for indoor deployment. The dual-band configuration, while sufficient for typical home use, may fall short for environments with a very high density of simultaneously connected devices, where a tri-band setup would better distribute the load. Additionally, users who rely on DLNA-based media streaming to compatible TVs or players will need to look elsewhere, as the router lacks DLNA certification. Those requiring longer hardware coverage may also find the one-year warranty limiting for a device expected to handle continuous network traffic over several years.

The Archer BE400 comes with a thorough set of security capabilities built in. At its core, it includes a built-in network firewall with SPI intrusion protection and DoS protection, helping guard against common network-level threats. Wi-Fi connections are secured through WPA, WPA2, and WPA3 protocols, while MAC address filtering, URL filtering, port filtering, and a Network Services Filter give administrators additional control over what traffic is permitted. VPN passthrough is supported for L2TP, IPsec, and PPTP, and a PPTP server is also available on the device itself. On the IP management side, the router handles both automatic and static IP addressing, and NAT is supported alongside parental controls for household-level access management.
