There are several ways to improve the performance of WiFi networks at home, such as moving the location of the router, finding out where in the house there is interference with neighbors, choosing the most appropriate channel or placing WiFi repeaters that allow us to improve the quality of our wireless network.
Keep reading this article to learn all about WiFi repeaters, how they work, where it is best to place it, what are their advantages and what to pay attention to when buying one. Let’s go!
What to keep in mind about WIFI repeaters?
As I’m sure you’ve experienced at one time or another, you don’t have the same wireless coverage in all parts of your home. With a single router, WiFi may not be able to reach all rooms in a house or office. This is why a WiFi repeater may be a partial solution.
An amplifier, as its name suggests, extends the coverage and reaches more spaces and improves the signal, preventing coverage saturation.
How does a WIFI repeater work?
As for the operation of a WiFi repeater, it is quite simple. These devices contain two wireless routers. One of them has the function of picking up the WiFi signal that already exists in your home. When it is received, it is transferred to the second router to transmit it again, boosted so that it has more range and covers the areas of the home that the main router does not reach.
That is, imagine that you have a router installed in your living room, but your bedroom does not have enough signal to connect your computer to the network. Then, the process would be to connect the WiFi repeater at an intermediate point between the living room and your bedroom so that the WiFi signal from the living room can reach you and the repeater can emit an amplified signal to reach your bedroom.
The key is the place where the repeater is placed, for its correct operation the ideal area is the intermediate between the main router and the area where you want the coverage to reach.

Types of antennas
- Directional antennas: As the name implies, these antennas direct the signal in a very specific direction. They are able to pick up the signal from distant WiFi networks. They can be used to capture your own home router. But the most common is to install it outdoors to capture WiFi networks located in another building, or even in a distant place in a mountain or on the other side of the city. The most professional antennas have a range of up to 1 kilometer.
- Omnidirectional antennas: This type of antenna is the most common in WiFi Access Points, especially for indoor use and transmitting in all directions. However, the coverage radius is not completely spherical so it must be taken into account that there will be points where the signal does not reach, for example just below the antenna could be a blind spot. Omnidirectional antennas theoretically send information at 360 degrees, i.e. no orientation is required. However, the range of these antennas is less than that of directional antennas.
- Sectorial antennas: They are capable of radiating horizontally at certain degrees, such as 45º, 60º, 90º or even 180º antennas. They are capable of reaching farther and are typically used by WISP operators to provide coverage to several customers at once.
Advantages of WiFi repeaters
The main advantage of the wifi repeaters is their easy installation and use of the devices. All you need to do is plug the adapter into the power supply at an intermediate point between the router and the farthest place you want the coverage to reach you.
On the other hand, in most cases the configuration is done automatically, by pressing some synchronization button or having to change some parameter if we want to, such as the password.
Installation and startup is usually done in a simple way through LED codes, which indicate the optimal point where you plug the amplifier, then pressing the WPS button or through a mobile application.
In addition, the cost of WiFi repeaters is not very high, not exceeding €100.
What to consider when buying a WiFi repeater?
After seeing what you are looking for in purchasing a Wifi repeater and knowing how it works, it is important that you know what aspects you should pay attention to when buying one.
- Type and quantity of antennas: You must see if they are external, orientable, if they have a good performance, or if you need an internal antenna.
- Supported frequency bands: The most basic repeaters work with 2.4 GHz, but if we want a future-proof equipment it should also be 5GHz.
- Power indicator: This is a simple but useful function. Some models have LED lights that indicate how strong the WiFi signal reaches that particular point. This information helps us to locate the repeater in the best possible area of your home.
- Transmission speed: The higher the number the better, although you should know that it is difficult to reach the number set by the manufacturer. However, it is advisable that the figure is at least equal to or higher than that offered by the home router in order not to lose speed in the network as a whole. red.
