The HUAWEI 5G Mobile WiFi automatically selects a Wi-Fi channel with less interference in an environment with strong interference. As a result, the channel 52–64 is selected occasionally. In this case, the Mobile WiFi needs to be silent for 1 minute according to regulations. At this time, the LCD displays a message indicating that the Wi-Fi availability is being detected to check whether radar signals exist on the current channel. During this period, the mobile phone cannot find the Wi-Fi name. After the scanning is complete, the Mobile WiFi can be used normally.
