每当我打开笔记本电脑的盖子时，WiFi就会切换。我正在使用 Manjaro KDE。在节能设置中设置“不执行任何操作”没有帮助。交流电源和电池都会发生这种情况。蓝牙不受影响。
这是journalctl盖子打开事件的输出。

另外，还有一些有关我的系统的其他信息。

答案1
当我把它放到Manjaro论坛上时，问题就解决了。解决方案如下：
/etc/NetworkManager/conf.d/90-disable-randomization.conf使用以下内容制作配置文件 ：[device-mac-randomization] wifi.scan-rand-mac-address=no [connection-mac-randomization] ## FOR ETHERNET, OPTIONAL IF YOU USE ONLY WLAN #ethernet.cloned-mac-address=permanent wifi.cloned-mac-address=permanent然后重启NetworkManager.service
systemctl restart NetworkManager.service
（尽管我必须重新启动才能使其工作。）
