The window10 system will always appear. It will not play for a while after booting, the wifi will be automatically disconnected, and the connection will no longer be connected. Just restart the computer.
But this is not a long-term solution after all, and the problem needs to be solved from the root cause.
Control Panel---Network and Internet---Network and Sharing Center---Change adapter settings
Find WLAN, right click-Properties-Configuration-Power Management-and then cancel the check mark below
Analysis reason: Visual inspection is that the garbage win10 has done power-saving treatment, and the wifi is automatically turned off, but it will not be turned on automatically. Just cancel this automatic shutdown here.
