Aluminum foil, the simplest trick to improve the WiFi signal at home: how to do it step by step

Poor WiFi connectivity often causes headaches in almost every home. In a context where cell phones, computers, video game consoles and even televisions need a fluid Internet connection, the signal strength It is decisive to have The best experience.

An effective homemade trick can help improve service. Home WiFi routers use their antennas to send the signal generally 360 degrees around them. Anyone who in a certain environment does not receive the right signal to enjoy their devices connected to the Internet can appeal to the foil or some reflective material near the antennas.

According to researchers at Dartmouth University, surround the router antennas with aluminum foil or a can It serves to improve the signal, reduce interference and create barriers to increase the security of the connection.

“This improves the efficiency of wireless infrastructure in buildings by mitigating the impact of insulation, partitions and interior layouts,” say Dartmouth engineers, as reproduced in the BBC.

By putting an aluminum foil barrier on it, the signal becomes directional, that is, it points in only one direction. Thus, in an apartment you can put a sheet of aluminum foil on the router that only points towards one place. The other spaces will lose connectivity, but this will be concentrated in the most necessary place.

The Dartmouth researchers took this homemade trick to a more sophisticated level, creating a system that prints 3D models that point the signal wherever you want. After the figure is printed in plastic, it is covered in aluminum foil, and that’s it.

Aluminum, the ideal partner for the WiFi router: how to install it step by step

This material, which can be used in different ways at home, especially for cooking, is also an ideal ally to improve Wi-Fi connectivity in certain situations.

A common way to use aluminum in this sense is build a reflector antenna using typical roll paper that you get in any supermarket or sheets. Due to its conformation, it is a malleable material that fulfills this specific task.

To direct the signals towards a certain part of the home, simply create a “C” shape with the aluminum foil and place it behind the Wi-Fi modem: The concave part should hug it facing the area where you want to improve the signal intensity.

Now, if the router is in the center of the home and the Wi-Fi signal loss occurs in two different directions, you will simply have to use an “S” shaped antenna and follow the same steps.

This satellite dish is placed behind the WiFi router antenna, and its shape helps to direct the signal in a specific direction. This can be useful to focus the signal in a specific direction and increase the signal strength in that area.

The option of building homemade aluminum antennas can be a good option. These antennas can be useful to extend the range of the WiFi network or to direct the signal towards a particular area.

In some cases, placing aluminum sheets near a WiFi router’s antenna can help reflect the signal in a desired direction. For example, someone who searches extend WiFi coverage to a specific roomyou can place a sheet of aluminum behind the antenna and point it towards that room.

Aluminum can sometimes help prevent electromagnetic interference that affects the WiFi signal. For example, if you have appliances or other electronic devices that interfere with the WiFi signal, you can use aluminum sheets to block those interferences and improve the signal.

Although aluminum can be useful in certain situations to improve WiFi connectivity, those who lean towards the aluminum option should keep in mind that its effectiveness may vary depending on your network configuration and the environment you are in.

Another thing to keep in mind when assembling this home satellite dish is to be careful not to completely block the signal or damage the router antenna. It is always advisable to experiment with caution and consider other solutions, such as placing the device in an optimal location or using Wi-Fi repeaters, before resorting to aluminum.
