What is the cause of frequent disconnection from mac connection to Wi-Fi network?

How to solve the problem that the mac connection to the Wi-Fi network is not smooth:

Apple comes with a "wireless diagnosis" tool on Mac devices.

"Wireless Diagnostics" can help Mac users detect some common Wi-Fi connection problems, and monitor the WiFi connection to find out the cause of intermittent connection failure, and then report the problem to us.

On the page, click "continue" and then we find the "wireless diagnosis" system that will automatically check. Of course, this will automatically check the WiFi configuration settings.

After checking, click "continue"-"summary" and then click "additional information". You can enter the description of the Wi-Fi network or the location of the router. The information attached here will be stored in the log file.

Click "continue"-"vro Information. Users can enter information such as the brand, model, and firmware version used by the Wi-Fi base station or router, which will also be stored in the log file.

Click "continue" to view "Wireless Diagnostics". Then, the faulty network will be found and I will be notified of the fix. After the fix is complete, click "close ".
