TP-Link Archer BE400 is a dual-band wireless router supporting the Wi-Fi 7 (802.11be) standard. It can simultaneously transmit wireless networks in the 2.4 GHz and 5 GHz bands, using IEEE 802.11 b/g/n/ax/be protocols in 2.4 GHz and IEEE 802.11 a/n/ac/ax/be protocols in 5 GHz. The maximum theoretical throughput is 574 Mbps in 2.4 GHz and 5760 Mbps in 5 GHz, for a combined BE6500 class.
The router is equipped with multi-gigabit Ethernet ports, including a 2.5G (WAN/LAN) port and gigabit LAN ports, enabling the creation of a high-capacity wired network. With Wi-Fi 7 technologies such as 320 MHz channel width, 4K-QAM, and Multi-Link Operation (MLO), the device delivers higher performance, lower latency, and more stable connections – essential for online gaming, streaming, and tasks that require low latency.
The Archer BE400 is designed for home and office users who need a reliable, high-capacity network. With support for multiple simultaneous connections, it performs well in environments with many active devices, ensuring fast and stable wired and wireless connectivity.

WiFi 7, WiFi Like Never Before

TP-Link Archer BE400 is a dual-band wireless router based on the Wi-Fi 7 (802.11be) standard. The device operates in two frequency bands, 2.4 GHz and 5 GHz, achieving a combined BE6500 class throughput – up to 574 Mbps in 2.4 GHz and 5760 Mbps in 5 GHz.

Wi-Fi 7 introduces a range of technologies that enhance performance and connection stability:
320 MHz channel width – channels twice as wide compared to Wi-Fi 6/6E, significantly increasing throughput.
4K-QAM – higher modulation enabling more data to be transmitted within the same band.
Multi-Link Operation (MLO) – simultaneous transmission across multiple bands, reducing latency and improving connection stability.

The router is equipped with multi-gigabit Ethernet ports, including a 2.5G (WAN/LAN) and gigabit LAN ports, allowing the creation of a high-capacity wired network. With these features, the Archer BE400 ensures fast and stable connections, low latency, and high reliability – particularly important for online gaming, streaming, and environments with many active devices.
