In today's digital era, home internet is no longer limited to entertainment only. Many essential activities like studying, office meetings, online banking, video calls, smart TV and streaming are now dependent on a stable Wi-Fi connection. Despite this, internet speed is not the same in every part of the house. The signal is strong near the router, but it may lose strength as it reaches another room, corridor or balcony. In such a situation, some easy home remedies can be tried before buying a new expensive router.
Why is aluminum foil useful?
The metallic surface of aluminum foil has the ability to reflect radio waves. This same property can be used to focus the Wi-Fi signal in a particular direction. If the foil is placed behind the router's antenna in a properly curved shape, it can help send the signal more effectively in the direction where connectivity is weak. However, its effect will not be the same in every home, because the position of walls, furniture, routers and nearby electronic devices also affect the network.
use of parabolic reflector
A parabolic reflector made of foil can reflect radio signals in a limited direction. Dartmouth College's WiPrint study reported significant improvements in wireless signal strength in some circumstances using such reflectors. However, this cannot be considered a universal solution. This can be beneficial in the direction where the user wants better coverage.
Easy solution with cardboard and foil
A simple reflector can also be made from empty tissue or paper rolls available at home. Cardboard can be covered with aluminum foil and placed behind the antenna in such a way that the reflected waves go in the required direction. This is a low-cost experiment, but it is important to take care not to damage the antenna and router while installing it.
Soft drink can also option
A semicircular reflector can be made by carefully cutting an empty aluminum can. Placing it behind the router can help reflect radio waves in one direction. However, the cans may have sharp edges, so for safety's sake they should not be left open.
Don't depend only on foil
Correct location of the router is also important for better Wi-Fi. It should be kept in a relatively central part of the house, in an open and high place. It is helpful to maintain distance from microwaves, thick walls, metal shelves and large electronic devices. The 5GHz band can be used as needed, while for longer distances 2.4GHz sometimes provides better coverage.
Use strong passwords and WPA2 or WPA3 encryption for network security. Keep updating the firmware of the router from time to time. In this way, the correct position of the router, suitable band and use of aluminum reflector as per requirement can together improve the home Wi-Fi experience.
