TP-Link RE605X: What to Know
The RE605X is a dual-band WiFi 6 extender. Per the listing's own feature bullets, it uses two high-gain antennas to extend a router's signal into weak areas and eliminate dead zones, with dual-band speeds up to 1.8 Gbps - 1201 Mbps on the 5 GHz band and 574 Mbps on the 2.4 GHz band. That is the kind of throughput claim that matters most for streaming, gaming and downloads on devices that sit far from the router.
On capacity, the listing says it connects up to 30 devices that are out of range from the main router, and it includes a Gigabit Ethernet port for wired connections to a PC, smart TV or gaming console. That wired port is a practical differentiator if you have one device - a console or desktop - that you would rather not run over WiFi at all.
Per TP-Link's own description, the RE605X also supports OneMesh, which lets it form a single-network mesh with a compatible OneMesh router rather than appearing as a separate network name. If you own a OneMesh-capable TP-Link router, that is the cleanest way to use this unit; with other routers it still works as a standard extender.
