What Materials Can Block WiFi Connection?

The purpose of my project is to find out what is interfering with my WiFi work and why it is always off.

A man named George majoring in science conducted experiments, they took a remote control and a car and covered it with a material to see if the remote control could keep moving the car. They see metal like copper reflects and absorbs radio waves

The boy named Tomas wondered if the result would change depending on the amount of material I used to block WiFi. He discovered that radio waves can pass through or bypass objects regardless of the number of radio waves.

My argument is to prevent the material of iron from greatly influencing the radio waves. There is evidence that aluminum foil and steel pan are most effective in my experiment. Among all other materials, their DBM average is the lowest. This proves that my argument is correct. My other argument is that paper items like cardboard do not affect the radio waves connecting the router to the equipment. During the experiment, I found that my words are wrong. DBM is affected even if it is not so big, but it has the least impact.

My statement is correct, as the iron material used in the experiment caused the greatest difference.

This can be a physical obstacle. The radio waves pass most of the material, but it may be blocked or absorbed by the conductive material. Water is conductive. In other words, our bodies may actually interfere with WiFi. But do not panic, radio waves will not damage cells. It can also be interference. Because WiFi uses radio waves (and there are many radio sources including space), these radio waves may collide with each other and interfere with the signal. In fact, your microwave oven will operate in the 2.4 GHz band. That is, it interferes with WiFi depending on the type of WiFi used (2.4 GHz or 5 GHz).

Can you imagine broadcasting a WiFi signal in the air that broadcasts on radio to make your WiFi device work? This is the truth! The problem is that WiFi signals are sometimes blocked by various things no matter where you are. This is because the WiFi signal received by your device is always weaker than the intrinsic strength you should have. We usually have a lot of furniture at home: usually sofas, wardrobes, cabinets, tables, chairs, beds etc. Usually, most are not obstacles, but if they are big enough and the WiFi router is nearby , The signal becomes significantly weaker. Therefore, please do not hide the router behind large furniture such as sofa and bed, or place it between furniture and wall.

In the garage, the phone can still connect to the wireless network inside the house, but this is a weak signal. It will take several blocks before switching to cellular connection. I have been to this doctor enough to know the point of how to get there, but like we said, we ran very late. Anyway, I called a passenger seat and started driving, waiting for instructions. So after a few blocks, I think I had a heart attack. However, there is palpitations on my right wrist, there is no pain in my left arm. I found that AppleWatch works with your mobile phone map application. As you turn, the watch signals; this is clearly for my heartbeat
