    如题，电脑不操作待机或者睡眠一段时间后，唤醒就会提示Wifi 该设备已删除，网络显示没有连接，Wifi无法使用

    唤醒后

    此时尝试查看网络状态，是开启的，但是感觉网卡跟无线难道是分开的？

    猜测这是系统休眠前networkmanager释放网络资源的地方.

    /usr/lib/systemd/system-sleep

    https://wiki.archlinux.org/title/Power_management#Hooks_in_/usr/lib/systemd/system-sleep
    休眠和返回的时候,会执行这个目录下的脚本,调用时会传递 pre 和 post 参数的样子.

    参考https://wiki.archlinux.org/title/Power_management#Hooks_in_/usr/lib/systemd/system-sleep ,编个脚本塞这里post 时让networkmanager重连网络,应该就能解决问题.

    当然不知道问题是怎么产生的.
