We are going to explain what a WiFi repeater is and how it works. It is one of the main alternatives to the PLC that you have when it comes to improving the WiFi signal in your home and getting it to reach the corners where you have less coverage. Hence, especially if you want to choose a repeater to buy, it is important to know how they work.
A WiFi repeater is a straightforward device, so you will immediately understand how it works. But so that no one is left with any doubt, we are going to try to explain everything simply, first what it is and then how it works and how you can make sure you get the most out of it.
What is a WiFi repeater?
A WiFi repeater, also called a WiFi amplifier or adapter, is one of the devices you can find to expand the coverage of your home network. Yes, wired connections are the best from a speed point of view, but it is not always possible due to the distance and number of devices to connect. And even the range of your router has its limits too.
And it is precisely at this time that WiFi repeaters come into use as the cheapest alternative to expand the coverage of your network. What they do is capture the signal of the WiFi network that you already have in your home, and expand it to go further. The signal is the same, with the same name for the WiFi and the same password.
Therefore, what we have is a device that acts as a bridge between the area where you have good WiFi coverage and the area to which you want to extend it due to having a weaker signal. It does this by capturing the WiFi signal that reaches it, and then amplifying it with its antennas.
This kind of “bridge” works in both directions. This means that it not only takes the data from your router to an area where its original coverage does not reach but also collects the data from the devices that are in that same area and sends it back to the router so that there can be a smooth connection. , and the experience is the same as if the router were there.
In some cases, in addition to extending existing networks, some extenders also create their own completely independent WiFi network, with a different name and password. This has the downside that you’ll have to reconfigure your devices to connect, though if you’re always going to have those devices connected to the extender, it’s a lesser evil for better performance.
