    Installing a PLC is one of the best ways to bring the Internet to any home. Interference become minimal obstacles and no longer represent a problem, this is because the signal travels through the wires, but how to properly configure a PLC? While it may sound complicated, it isn't at all.

    How a PLC works

    PLC stands for Power Line Communications. Powerline is a technology that uses the electrical wiring of a house to transmit the data signal. In this way, Powerline technology converts a conventional power line into a digital broadband line, through which we can connect to the Internet or connect computers in a local network.

    How was it made? I don't want to overload you with technicalities, and maybe you just need to know that Powerline networks modulate that signal so electricity and data don't get in the way of each other. This is why electricity continues to function normally after installing a PLC.

    Therefore, Powerline networks only use existing power lines to transmit data, in this case an Internet connection or a local network. This has the obvious and immediate advantage of not having to lay new cables around the house, which is a relief and comfort, as well as a cost saving.

    How to properly install a PLC at home

    In this PLC installation tutorial we will explain how to do it step by step. PLCs are usually adapters that plug into one socket and send the Internet signal to another card located in another socket. Both devices have an Ethernet port so you can connect the modem on one side and the computer on the other. However, since the PLC occupies one socket, some are already equipped with an additional socket.

    Some even create a Wi-Fi hotspot, so you don't necessarily have to connect via cable.

    1. Connect the router to the input PLC

    The first step for install a PLC at home is plugging the device into an outlet. It is obvious, since there must be an access point for the Internet to travel across the power grid.

    Of course, very important: connect the PLC directly to the socket, not to a terminal where several other electrical devices have been connected. If you don't follow this advice, your connection will be unstable and of poor quality.

    When you have the device plugged in, connect the modem to the PLC using an Ethernet cable, preferably a high-speed Gigabit, although these are usually included in the package.

    2. Connect the device to the output PLC

    Have you already completed the first step? Well, now there is the Internet in your home's electrical current - to put it simply - but there is no receiving device connected to it.

    Therefore, you need to take the laptop or device that you want to connect to the Internet and go to the room where you want to get the Internet signal. Let's say, your office.

    When you are there, take the other PLC, let's call it out and plug it into a socket. Once again, we repeat the warning: you need to plug it into an exclusive power outlet, with no other devices connected.

    If it has already been connected, repeat the procedure performed with the modem: connect the computer to the PLC via an Ethernet cable. That should be enough for instant connection.

    3. Do you have the Internet?

    There is a very simple way to check if you have correctly installed a PLC: turn on your computer and connect to the web. If it doesn't open, you haven't read our guide well.

    Or perhaps it is due to interference of the electrical network with the Internet signal, or because you have not followed all the steps as we have said, especially that of connecting the PLC to an outlet with only the device connected or because the electrical system of your home is defective.

    4. My PLC is not working: what did I do wrong?

    You have connected everything as explained in this tutorial to configure a PLC, but it does not work.

    There are many things that may have gone wrong with these devices, even if they work perfectly fine. It should be borne in mind that when the signal travels through the electrical network, it is very sensitive to interference of all kinds. As already mentioned, the state of the wiring can adversely affect the strength and quality of the signal.

    If your house is of old construction, this is certainly a problem. Cables have deteriorated over time, and while they carry electricity properly, they're not exactly good for connecting to the internet.

    Another possible problem for which the PLC does not work is that there is a high-power device near the plug where it was placed. Air conditioning, washing machine or dishwasher are the suspects.
