Why the WiFi router at home loses signal and what solutions to adopt

Reasons for Wi-Fi going bad

If you see that your Wi-Fi loses signal, that it is not working as well as you would like, it is most likely due to one of the causes that we are going to see. There are different options that we are going to be able to take into account to solve it. Usually, just by carrying out a few simple steps we can achieve greater stability in the wireless network.


The first reason why Wi-Fi loses signal is due to distance. This technology is limited in this sense and as soon as we move away from the router or access point we begin to lose coverage. It is not the same to be connected a meter from the router than to do it from another room that is 20 meters away.

What can we do to save this problem? Something very useful is to use devices that enhance the Wi-Fi signal or allow take the connection further. For example we can install Wi-Fi repeaters. These devices act as a bridge between the router and the equipment that we connect and thus enhance the signal.

But there are other alternatives, such as Wi-Fi Mesh systems or PLCs. The latter, moreover, are interesting for long distances when using electrical wiring. A way to be able to take the connection to a place that is far from the router and that the signal loss is minimal.


Another reason why the Wi-Fi network does not arrive well is because of the obstacles that may exist. For example a wall, a wall, a piece of furniture… All this will influence and can block signal. There are things that affect much more, such as an iron plate. It is in these cases when we must be more careful.

Ideally, to avoid problems of this type, or at least reduce them, is to keep the router or access point isolated from anything that can block the signal. The freer you are, the better. In this way you can send a signal to a higher range and have no speed or stability issues.

Once again, in order to improve the connection, something we can do is have devices such as repeaters, Mesh systems or PLC. In this way we will be able to take the signal further, despite the obstacles that may exist.


Wi-Fi can also be affected by having other devices or appliances nearby. For example, something that can damage the signal a lot is that there is a microwave close to the router. The 2.4 GHz band, especially, could be severely limited. These interferences will affect the speed and stability of the Internet.

The solution is simple: move the router away from any device that can create interference. This includes appliances, but also any device that works over Wi-Fi. All this can affect the quality of the signal and cause continuous dropouts.

Wrong Band Usage

Are you using the most optimal Wi-Fi band? There are two options: the band of 2.4 GHz and 5 GHz. Each of them is better according to the circumstances. For example, the first one is ideal when we connect far from the router, although it does not offer as much speed. On the other hand, the second is faster, but more sensitive to distance and possible obstacles.

It is essential to choose at all times which band are we going to use to optimize the connection. The Wi-Fi may lose a signal because we are using the one that is not convenient for us and that hinders its proper functioning.

In short, these are the main reasons why Wi-Fi can go wrong. It is essential to know the causes to, later, try to find a solution that helps us to have the best possible connection and always maintain a good speed.
