Overview

The TP-Link RE605X is a Wi-Fi 6 range extender designed to extend an existing Wi-Fi network. It supports dual-band operation (2.4 + 5 GHz), has one Ethernet port rated up to 1 Gbps, and plugs directly into a wall socket.

Who it suits

This suits users who want to extend coverage of an existing dual-band Wi-Fi 6 network without adding 6 GHz support. It is also suited to those who want to wire a single nearby device via the Ethernet port while using the extender in access point mode.

Reasons to consider it

It supports both Range Extender and Access Point modes, giving some flexibility in how it's deployed. The single Gigabit Ethernet port allows one wired connection, and the wall-plug design means no separate power adapter is needed.

Limitations and compatibility checks

There is no 6 GHz band support, so it is limited to 2.4 and 5 GHz. It has only one Ethernet port and no wired backhaul support, which may limit wired setups or multi-device wiring. No ecosystem is specified, so compatibility with other TP-Link mesh systems is unclear.
