The network in the dormitory building has suddenly become very weak in the past two weeks. I called the telecom and said that someone might have opened the signal jammer and asked me to find the property management. It is impossible for students to turn on any signal jammers. What should I do and the network will be restored as soon as they leave the dormitory building?

Check for yourself whether only the signal of Telecom has become weak, or the signals of China Mobile, China Unicom, and Telecom are all weak. If only one of them becomes weak, it may be a problem for the operator. The current wifi jammer is full frequency bands, which can block all 2G 3G 4G signals, and 2.4G WIFI signals under the three operators of China Mobile, China Unicom, and China Telecom. If the Wi-Fi and the mobile phone signals of the three major operators are all weakened, it may be that a wifi signal jammer is installed. If this is the case, only install a mobile phone signal amplifier near the place where the signal blocker is used to increase the mobile phone signal. When the mobile phone signal becomes stronger, the blocker is more difficult to block.
