In order to have a good Internet connection we can make use of some devices that help improve the signal. An example is the PLC, which are very useful devices to bring the connection from one place to another in the house. However, they can sometimes malfunction. In this article we are going to explain what can cause interference in PLC devices and in this way prevent this from happening and keep your connection in good condition.
What causes interference in PLCs
The PLCs are going to work through the electrical wiring . Therefore, if there is interference or something that causes problems, the connection will start to go worse. That can affect whether you connect via LAN cable or via Wi-Fi. Preventing this from happening is the objective of this article and you must take into account some points.
Electronics devices
The first cause for interference in PLCs is when you have electronic devices nearby . For example a computer, a television, etc. These devices can negatively affect the operation of PLC devices and cause them to perform poorly, not offering good speed and stability.
Our advice is to place them as isolated as possible. You should always keep them away from other electronic devices, whatever they may be. In this way you will avoid problems if you need to take the connection from one place to another in the house.
Use a ruler
When we connect the PLCs to the electrical network, one option is to plug them into a power strip . A clear reason is not having free sockets and wanting to connect other devices. But this is actually a mistake. It can cause them to not work properly and have trouble achieving good speed.
In this case, what you have to do is connect the PLCs directly to the wall. Avoid connecting them through power strips or any plug that is not directly on the wall. Only in this way will you get the connection to go directly to the electrical network, without there being interference that affects the quality of the signal.
Several outlets nearby
Something similar can happen when you connect the PLCs to a socket and you have others nearby. In those plugs you may have other devices connected, so there will be interference. This is common in some homes where we can see two or more plugs that are practically next to each other.
If this is your case, it is best not to connect the PLCs when there are several outlets nearby. At the very least, avoid plugging them in if you already have any devices plugged into these other outlets. The more isolated they are, the better.
Use the integrated plug
Although it may seem like an advantage, the fact that PLCs have an integrated socket is a problem. They are used to connect other devices and not do without a plug, but it is a mistake to use them. What you are going to achieve is that there is interference and the connection works worse, similar to when you connect it to a power strip.
Therefore, once again, the ideal is that these PLCs are connected directly to the wall and if they have an integrated plug, do not use it. You can connect several PLCs to have Internet, but always avoid using these plugs.
