The apartment I live in has a 4G signal in the corridor. As soon as I enter the room, the signal on the bed is one bar or no signal. Is the apartment installed with a wifi jammer device or something? What should I do?

Answer
Can you try if the mobile phone signals of China Mobile, China Unicom, and China Telecom are all missing? Or just one of the signals is not good. If the signal of one of them, such as mobile, is not good, you can call the mobile operator for consultation. If all of them are not good, a wifi jammer may be installed. In this case, you can only install it. The signal amplifier is used to amplify the signal, and the signal becomes stronger, and it is difficult for the shielding device to shield it.
