WiFi Repeater: what it is, how they work and what you should keep in mind

A WiFi repeater is a network device connected to a socket. That can extend the reach of our Internet connection so completely wireless. Although there are models that can connect to our router so wired through an Ethernet port.

Its usefulness is beyond doubt because a WiFi repeater allows us to cover dead zones. Those in which the signal from our router does not arrive and therefore there is no Internet connection. And also helps us improve the quality and stability of the signal in other areas where the WiFi connection is very weak.

WiFi repeaters have two great advantages: they are very easy to use. Since they do not require complicated configurations and allow us to clone the settings of our network (router settings). And they are very economical (we can find very good models for about 20 euros ).

Usually to use a WiFi repeater just plug it in and carry out the synchronization process with our router. We can do it automatically through WPS or manually, two very simple and fast processes to complete.

What possibilities do they offer?WiFi Repeater

A WiFi repeater is responsible for repeating the Internet connection of our router extending the scope of it wirelessly. That is its most important difference compared to a traditional PLC based on cable.

The most basic models work under the WiFi N standard, operate in the 2.4 GHz band and reach maximum speeds of 300 Mbps. There are also models compatible with the WiFi AC standard that operate simultaneously in the 2.4 GHz and 5 GHz bands, either real or “simulated” (when the router does not work in the 5 GHz band but the repeater does).

As we have indicated at the beginning of the article a WiFi repeater allows us to extend the signal range of our WiFi connection to eliminate dead zones and to improve the speed and stability of the signal in a simple, economical and reliable way.

However, we must bear in mind that not all repeaters are equal and that we will have to choose a specific model based on our basic needs, making a short and medium term assessment.

Tips to choose and to use them correctlyWiFi Repeater

As we have already said, the WiFi repeaters are very easy to use. But we must bear in mind that their scope is limited and that therefore we do not have to hurry distances since getting out of the optimal level trying to speed up a few meters can end up being counterproductive.

Most repeaters come with a signal indicator that helps us find the optimal placement point. So we just have to let ourselves be guided by it. And avoid placing it at such a large distance that it reduces the intensity of the signal reflected by that indicator. In this sense, the ideal is not to sacrifice any line of the indicator.

When choosing a repeater it is important to take into account our needs and our budget. The most basic models with WiFi N at 300 Mbps that only work in the 2.4 GHz band can be a good option to extend the reach of our connection with a minimum cost. But if we want to enjoy greater performance and benefits offered by the 5 GHz band. The idea is to go for a model that works with both simultaneously. And that is compatible with WiFi N and WiFi AC.

There are WiFi repeaters with extendable antennas that can also be oriented in certain directions. They are not essential as most WiFi repeaters with integrated antennas work without the problem. But can be helpful in some specific cases.

Finally, it is important to take into account the configuration possibilities offered by a Wi-Fi repeater at the software level. Both in terms of security and network management and the possibility of configuring it as an access point.
