The TP-Link TL-WA850RE is a compact 300Mbps Wireless N Wi-Fi Range Extender designed to improve wireless coverage and eliminate Wi-Fi dead zones in homes, offices, apartments, shops and other small environments. It receives the existing wireless signal from your router and extends it to areas where the original Wi-Fi signal is weak or unavailable.

Operating on the 2.4GHz band, the TL-WA850RE supports wireless speeds of up to 300Mbps under 802.11n conditions. It is compatible with IEEE 802.11b/g/n wireless standards, making it suitable for extending many existing 2.4GHz wireless networks.

Its compact wall-mounted design makes installation simple and flexible. You can place the extender between your router and the area experiencing weak Wi-Fi coverage. The built-in signal indicator helps you identify a suitable location by showing the strength of the signal received from the main router. TP-Link recommends positioning the extender where at least three signal lights indicate a good connection.

The TP-Link TL-WA850RE also features a 10/100Mbps Ethernet port, allowing it to operate as a wireless adapter for Ethernet-enabled devices such as smart TVs, desktop computers, game consoles and other network equipment.

Setup can be performed using the extender button and your router’s WPS function, while compatible versions can also be managed through the TP-Link Tether app. This makes it easier to configure and monitor the device from a mobile device.

The extender includes features such as WMM, wireless MAC address filtering, wireless statistics, LED control and power scheduling, depending on the hardware/firmware version. Wireless security includes WEP as well as WPA/WPA2-PSK options.

Technical Specifications

Wireless Performance

The TL-WA850RE supports up to 300Mbps wireless signaling using 802.11n on 2.4GHz. It also supports older 802.11g and 802.11b devices, with maximum signaling rates of 54Mbps and 11Mbps respectively.

The advertised 300Mbps is the maximum physical wireless link rate, rather than a guaranteed real-world internet speed. Actual performance depends on factors such as distance, walls, interference, router performance, connected devices and network traffic.

Ethernet Port

The built-in 10/100Mbps RJ45 Ethernet port gives the TL-WA850RE an additional function beyond basic Wi-Fi extension.

It can receive the wireless connection and provide network connectivity to an Ethernet-enabled device. This can be useful for devices such as:

• Smart TVs
• Desktop computers
• Gaming consoles
• Blu-ray players
• DVRs
• Set-top boxes
• Other Ethernet-enabled equipment

Important: The Ethernet port is 10/100Mbps, so it does not provide Gigabit Ethernet speeds.

Easy Installation

The TL-WA850RE is designed for straightforward installation.

WPS Setup

1. Plug the TL-WA850RE into a suitable power outlet near your router.
2. Press the WPS button on the router.
3. Press the Range Extender/WPS button on the TL-WA850RE.
4. Allow the devices to establish the connection.
5. Move the extender to a suitable location between the router and the Wi-Fi dead zone.

The built-in signal indicators can then help you determine whether the extender is receiving a sufficiently strong signal from the router.

Signal Strength Indicator

One of the useful features of the TL-WA850RE is its signal indicator system.

The LEDs indicate the strength of the wireless signal being received from the main router. This makes it easier to find a practical position for the extender instead of simply placing it wherever a power socket is available.

TP-Link recommends choosing a location where at least three signal lights indicate a good connection.

Compact Wall-Mounted Design

The TL-WA850RE uses a small plug-in design measuring approximately 110 × 65.8 × 75.2mm. Its wall-mounted form factor helps keep installation tidy while making it easy to reposition when necessary.

It is particularly useful in areas where a larger standalone networking device would take up unnecessary space.

Management and Control

Compatible versions of the TL-WA850RE can be managed through the TP-Link Tether app, providing mobile-based access to supported configuration and control features.

Supported management features may include:

• Wireless configuration
• LED control
• Night Mode
• Power scheduling
• Access control
• Wireless statistics
• Wireless radio control

Feature availability can depend on the hardware revision and firmware.

Wireless Security

The TL-WA850RE supports several wireless security options, including:

• 64-bit WEP
• 128-bit WEP
• 152-bit WEP
• WPA-PSK
• WPA2-PSK

For modern networks, the supported WPA/WPA2 options are generally preferable to older WEP security.
