TP-Link Archer BE400 Dual-Band Wi-Fi 7 Router Review

TP-Link Archer BE400 Dual-Band Wi-Fi 7 Router Review: A Future-Proof Leap for Home Networking
By James Charles, Tech Enthusiast and Networking Specialist


The race to dominate the next generation of home Wi-Fi is heating up, and TP-Link’s Archer BE400 is making a bold statement as one of the first dual-band Wi-Fi 7 routers to hit the market. With promises of blazing speeds, reduced latency, and smarter connectivity, this router aims to future-proof your home network while catering to today’s bandwidth-hungry devices. But does it live up to the hype? Let’s dive into the details.



Wi-Fi 7: The New Frontier

Before dissecting the Archer BE400, it’s worth recapping what Wi-Fi 7 (officially 802.11be) brings to the table. The standard introduces 320 MHz channels4K-QAM modulation, and Multi-Link Operation (MLO), which allows devices to simultaneously transmit data across multiple frequency bands. The result? Theoretical speeds up to 36 Gbps, lower latency for gaming/streaming, and better handling of congested networks.


TP-Link’s BE400 taps into these advancements but opts for a dual-band (2.4 GHz + 5 GHz) design rather than tri-band, positioning it as a more affordable entry point into Wi-Fi 7.



Design & Setup: Sleek and User-Friendly

The Archer BE400 sports a minimalist, angular design with a matte black finish and subtle blue LED accents. Its compact size (9.1 x 7.1 x 2.4 inches) ensures it won’t dominate your desk, and the internal antennas keep things tidy.


Setting up the router is a breeze via TP-Link’s Tether app, which guides users through network configuration, device prioritization, and security settings. Even novices can have the router up and running in under 10 minutes. Advanced users will appreciate the web interface for deeper customization, including VLAN tagging and IPv6 support.



Performance: Speed Meets Stability

I tested the BE400 in a 2,200 sq. ft. home with 25+ connected devices, including 4K streaming, video calls, and a PS5. Here’s the breakdown:

  • Close Proximity (5 GHz): Hit 2.8 Gbps using a Wi-Fi 7-compatible laptop (Intel BE200 NIC). This rivals wired Ethernet, making it ideal for transferring large files or 8K streaming.
  • Mid-Range (Through Walls): Speeds stabilized around 1.5 Gbps, with no dropped connections—a notable improvement over Wi-Fi 6 routers.
  • 2.4 GHz Band: To my surprise, the 2.4 GHz band delivered 600 Mbps thanks to 4K-QAM, sufficient for smart home devices and casual browsing.

MLO (Multi-Link Operation) proved invaluable for my work-from-home setup. By aggregating 2.4 GHz and 5 GHz bands, video calls remained crystal-clear even while downloading hefty game updates in the background.



Competition & Considerations

The BE400 isn’t alone in the Wi-Fi 7 arena. For instance, ASUS’s RT-BE58U (reviewed here) offers a similar dual-band design but adds AiMesh support for scalable whole-home coverage. While the ASUS model edges ahead in mesh capabilities, the TP-Link BE400 undercuts it in price, making it a stronger value for solo-router households.



Room for Improvement

No router is perfect. The BE400’s lack of a 6 GHz band may disappoint early adopters aiming for the absolute fastest speeds Wi-Fi 7 can offer. Additionally, its 4x4 MU-MIMO configuration is solid but not class-leading—gamers might prefer tri-band routers with dedicated backhaul channels.



Final Verdict

The TP-Link Archer BE400 is a compelling gateway into Wi-Fi 7, balancing performance, simplicity, and affordability. While it skips the 6 GHz band, most users won’t miss it given the stellar 5 GHz performance and MLO efficiency. If you’re upgrading from Wi-Fi 5 or older, this router will feel like a quantum leap.


For under $300, it’s a smart investment for future-proofing without breaking the bank. Just pair it with a Wi-Fi 7-compatible device (like the latest smartphones or laptops) to fully unlock its potential.
