请问 Win11 手动关闭无线网络后如何通过命令行开启

参考提问：Windows11 手动关闭无线网络后无法通过命令行开启


PS C:\Users\ms> Get-NetAdapter

手动关闭 WLAN 后通过终端执行：

没有响应


Enable-NetAdapter -Name "WLAN" -Confirm:$false

提示网络不存在


netsh interface set interface name="WLAN" admin=enable

运行日志


PS C:\Users\ms> netsh interface set interface name="WLAN" admin=enable  

此网络连接不存在。

什么逻辑呢，WLAN 开启状态下，打开终端管理员,可以通过命令，启动和关闭命令。

netsh interface set interface name="WLAN" admin=disable
netsh interface set interface name="WLAN" admin=enable

Disable-NetAdapter -Name "WLAN" -Confirm:$false
Enable-NetAdapter -Name "WLAN" -Confirm:$false

以上命令在无线网络开启状态下正常启动和关闭 wifi

但是手动关闭 WLAN 后

就不能同命令行开启 WLAN

希望有技术的大佬，交流交流经验。感谢大佬了~
