Verdict

The TP-Link RE815XE is a high-performance AXE5400 tri-band Wi-Fi 6E range extender that delivers combined speeds of up to 5,400 Mbps, distributed as 2,402 Mbps on both the 6 GHz and 5 GHz bands, and 574 Mbps on the 2.4 GHz band. Its standout features include a dedicated 6 GHz band to eliminate interference from legacy devices, 160 MHz channel bandwidth for doubled data throughput, and four external antennas supported by Beamforming and 6x high-power FEM for broad coverage. Major pros include its seamless roaming capability through TP-Link OneMesh, a versatile Gigabit Ethernet port for wired devices or Access Point mode, and easy setup via the Tether app. However, its significant physical size can block adjacent power outlets, and it has a relatively high idle power consumption of approximately 6.1W.
