Computer WiFi is sometimes disconnected and sometimes not? How to solve the problem of unstable computer WiFi

Some time ago, I bought a new computer at home, and I often encountered some minor problems during use. Take the wireless network for example. Once the system goes into sleep mode and then recovers, it will definitely not be able to connect. Due to work reasons, the author uses the sleep mode very frequently, so this problem also made me very puzzled. After some troubles, I finally found a trick to solve this problem. It's super simple!

2. In the Device Manager panel, find and open "Network Adapters", then find your wireless network card (usually with the words Wireless or WIFI, such as the one used in my computer is Intel(R) Wireless WiFi Link 496***GN), double-click it to open its properties panel;
