TP-Link RE605X AX1800 Wi-Fi 6 Range Extender | 1201Mbps 5GHz + 574Mbps 2.4GHz, Gigabit Ethernet

TP-Link RE605X is an AX1800 Wi-Fi 6 Range Extender designed to expand the coverage of an existing wireless network and improve connectivity in areas where the main router’s Wi-Fi signal is weak. It supports dual-band Wi-Fi 6 with a theoretical wireless rate of up to 574Mbps on 2.4GHz and 1201Mbps on 5GHz.

The RE605X can operate as a Range Extender or as an Access Point. Its Gigabit Ethernet port allows compatible wired devices to connect to the network, or it can be used in AP mode to turn an existing wired Ethernet connection into a dual-band Wi-Fi 6 access point.

AX1800 Dual-Band Wi-Fi 6

RE605X uses Wi-Fi 6 technology to provide dual-band wireless connectivity. The manufacturer specifies a theoretical wireless rate of 574Mbps at 2.4GHz and 1201Mbps at 5GHz.

The combined AX1800 class rating should not be interpreted as a single-device internet speed. It represents the theoretical PHY rates of the two wireless bands. Actual throughput depends on the source router, client device, distance, interference, channel conditions and the quality of the wireless backhaul between the extender and router.

Wi-Fi 6 Technology

The RE605X supports IEEE 802.11ax Wi-Fi 6 on both 2.4GHz and 5GHz. It is also backward compatible with earlier 802.11 wireless standards.

Wi-Fi 6 technologies such as OFDMA and MU-MIMO can improve wireless network efficiency when multiple compatible devices are connected. TP-Link’s current V3.8 firmware documentation also lists advanced AX feature controls for OFDMA, MU-MIMO and TWT.

2.4GHz and 5GHz Wireless Bands

The 2.4GHz band generally provides better coverage and wall penetration, while the 5GHz band can provide higher wireless speeds under suitable signal conditions. The best band for a particular device depends on distance, obstacles, interference and client compatibility.

Wi-Fi Range Extension

In Range Extender mode, the RE605X connects wirelessly to an existing router and retransmits the network into areas where the original Wi-Fi signal is weaker.

The Intelligent Signal Light helps users identify an appropriate location for the extender by indicating the signal strength between the extender and the host network.

For better performance, the extender should normally be positioned where it still receives a strong and stable signal from the main router rather than directly inside the dead zone.

Access Point Mode

RE605X can also operate as an Access Point. In this mode, an Ethernet cable connects the extender to the existing wired network, and the RE605X creates a dual-band Wi-Fi network.

This can be particularly useful when Ethernet cabling is already available. Because the wired connection becomes the network backhaul, AP mode can avoid the wireless backhaul limitations that can occur when using the device purely as a range extender.

Gigabit Ethernet Port

The RE605X includes 1× Gigabit Ethernet port. The port can be used for connecting compatible wired devices or for providing the Ethernet connection required by Access Point mode.

Compatible devices such as smart TVs, desktop PCs, gaming consoles, network printers and other Ethernet-enabled equipment can therefore connect to the extended network through the Gigabit port.

EasyMesh Compatibility

TP-Link currently lists the RE605X as EasyMesh-compatible. Compatible firmware and hardware combinations can be used with supported EasyMesh routers to create a mesh network with seamless coverage.

TP-Link’s India firmware documentation for RE605X V3.8 states that firmware version 1.2.10 added EasyMesh R2/R3 support, including traffic separation and DPP, as well as EasyMesh Ethernet backhaul.

OneMesh Support

RE605X also supports TP-Link OneMesh with compatible TP-Link routers. OneMesh-compatible configurations can provide a more unified wireless network experience across the supported router and extender.

OneMesh and EasyMesh are separate technologies, so compatibility should be checked against the exact router model and firmware being used.

TP-Link Tether App

The TP-Link Tether App can be used to set up and manage the RE605X from a compatible smartphone. TP-Link provides Tether support for Android and iOS devices.

Users can configure the extender, check its network status and manage supported wireless settings without requiring a traditional desktop-only setup process.

WPS Easy Setup

The RE605X includes a WPS button for quick setup with compatible routers. When supported by the host router, WPS can simplify the process of joining the extender to an existing wireless network.

A reset button is also provided for restoring the device to its factory configuration when required.

Wireless Security

TP-Link lists support for several wireless security options, including 64/128-bit WEP, WPA/WPA2-PSK and WPA3. The exact security options available can depend on the selected wireless mode and firmware version.

For modern deployments, WPA2 or WPA3 should generally be preferred over legacy WEP where compatible with the connected devices.

Smart Signal Indicator

The RE605X includes a Smart Signal Indicator designed to help determine where the extender should be placed. A suitable placement balances the distance to the main router with the coverage area that needs improvement.

Installing the extender too far from the main router can result in a weak wireless backhaul, while placing it too close may not provide meaningful additional coverage.

Technical Specifications

TP-Link RE605X for Home Wi-Fi

The RE605X can extend Wi-Fi coverage in homes where the main router does not provide sufficient signal in bedrooms, upper floors, living areas or other distant locations.

Its dual-band Wi-Fi 6 capability allows compatible clients to use either the 2.4GHz or 5GHz network according to their coverage and performance requirements.

TP-Link RE605X for Smart TVs and Wired Devices

The Gigabit Ethernet port allows devices without suitable Wi-Fi connectivity to access the network through Ethernet. It can also provide a wired connection for devices such as smart TVs, PCs and gaming consoles.

TP-Link specifically highlights wired connectivity for devices such as smart TVs, computers and gaming consoles.

TP-Link RE605X as a Wi-Fi 6 Access Point

When an Ethernet cable is available at the required location, the RE605X can be configured in Access Point mode. This converts the wired network connection into a dual-band Wi-Fi 6 wireless network.

This is useful for offices, homes, shops and other installations where Ethernet cabling is available but additional wireless coverage is required.
