Best Wi-Fi extenders 2021

Today, it has become much easier and cheaper to enchase a Wi-Fi signal than a few years ago. In this article, we will talk about the types of Wi-Fi signal extenders, including Wi-Fi booster amazon options, and the criteria for selecting these devices.

What is a Wi-Fi extender?

The Wi-Fi signal extender can be in several variations. First of all, you can amplify the signal at the expense of the transmitter itself, that is, the router. This can be done with a more powerful antenna. The second way is to amplify the receiver signal. But it must be borne in mind that when the signal is amplified, the radio wave becomes narrowly directed, so the amplifier must be clearly directed to the receiver or transmitter.

A Wi-Fi booster is an electrical device designed to amplify the signal transmitted over wireless Internet networks. It is a separate device that complements the router. Its principle of operation is quite simple – it must be installed at the boundary of the propagation of a wireless signal from a base station (router) in order to transmit this signal further. Such properties of the repeater allow you to organize continuous wireless network coverage in hard-to-reach or remote locations.

A wireless signal is a compact device capable of spreading a Wi-Fi network under the same network name as the base station. Thus, the user, moving around the territory, will be provided with access to the Internet, and his device will automatically switch between the base station and the repeater, choosing a source of a stronger signal. If the router operates in dual-band mode, you should select a repeater with the same properties.

The device does not create new networks. The device copies it with all the information that is transmitted, and simply expands it. The name and password of the network will not change.

When choosing repeaters, you should pay attention to their main characteristics, which include:

  • Wi-Fi network speed;
  • frequency range (frequencies at which the repeater receives / transmits wireless signals);
  • the number of built-in antennas (the degree of expansion of the signal receiving area will depend on this);
  • availability of required ports.

The best alternatives of Wi-Fi repeaters

There are the following devices:

  • TP-Link TL-WA850RE

This is a convenient repeater for your router that will quickly and easily increase the coverage area of the Wi-Fi signal. It is very easy to connect and configure the device. It will provide the most complete coverage in your apartment and eliminate dead spots. The signal transmission speed can reach 300 Mbps, which will be enough for games, videos, and movies.


Signal extender with 2 built-in antennas. It saves the profile so there is no need to reconfigure upon reconnection. The device is built using a dual band layout. It supports up to 300Mbps bandwidth, sufficient for watching videos, playing online, working with cloud storage, and more.

  • Asus RP-AC68U

The main task of this device is to increase the coverage of the Wi-Fi network. It copes with this task 100% because it provides uninterrupted connection on two bands: up to 1300 Mbps in the 5 GHz range and up to 600 Mbps in the 2.4 GHz range. Four internal antennas provide a large coverage area. The device can operate in several modes: amplifier, bridge, wireless access point.
