Some people joked that the basic needs of people nowadays are water, food and wireless WiFi. As a habit of playing mobile phones before going to bed, I am naturally no exception, but because of all the rooms, the room where I sleep is the furthest away from the room where the router is installed, and there are several walls in between. Therefore, I have been stuck with the problem of poor router signal. If the signal strength to my room can be enhanced directionally, the problem will naturally be solved. Is there any good way?
If your router can disassemble the antenna, you can naturally replace it with a better directional antenna, but because many cheap routers cannot disassemble the antenna, many people choose to work with existing antennas, including making parabolic reflectors with cans. The way. Although this method can make the antenna have a certain directivity, it is necessary to adjust the cans in order to achieve the best effect, so that the antenna can be located at the focus position of the parabola. Is there a simpler and better way to adjust?
Considering the principle of another directional antenna, we can use the principle of Yagi antenna to make another small thing. Yagi antennas use reflectors and directors to direct most of the signal energy to the front of the antenna. Use the original rubber antenna of the router as an active vibrator to directionally emit part of the energy.
You can use all non-conductive objects to make this fixed frame, such as this one cut out of a yogurt box, and open several holes for the copper wire and antenna to be inserted. The reflector and director are made of thick copper wire, 5.7 cm long and 5.08 cm long, respectively, and cut off with pliers. It is installed at a distance of 3.96 cm and 0.93 cm from the antenna on both sides of the original antenna. When in use, point one end of the short-spaced director to the direction where you want to improve the coverage effect, and use it normally. Generally speaking, this can improve the effect of the signal, so give it a try.
