The TP-Link RE605X AX1800 WiFi 6 Extender is pretty fast. According to the manufacturer's description, it can hit speeds up to 1.8Gbps, with 574Mbps on the 2.4GHz band and 1201Mbps on the 5GHz band. It should handle things like 4K streaming, online gaming, and several devices all at once without any major slowdowns.
It also supports TP-Link's OneMesh technology, which lets it work seamlessly with OneMesh routers like the Archer AX21. This creates a unified network across your home, so as you move around, your devices automatically stay connected to the best signal.
However, our research indicates that while OneMesh generally works well, a few folks ran into hiccups. Some had to update the firmware on both the extender and their router for everything to work smoothly. Others mentioned needing to tweak network settings, like disabling DHCP on the extender.
But once these issues were sorted out, it worked great.
So, if you make sure your firmware is up-to-date and handle any initial setup issues, the RE605X should give your home WiFi a solid boost in speed and reliability.
