打開蓋子時WiFi切換，忽略設置

每當我打開筆記型電腦的蓋子時，WiFi 就會切換。我正在使用 Manjaro KDE。在節能設置中設置“什麼都不做”沒有幫助。它發生在交流電源和電池上。藍牙不受影響。

這是關於journalctl開蓋事件的輸出。

當我把它放在 Manjaro 論壇上時，這個問題就解決了。解決方案如下：

/etc/NetworkManager/conf.d/90-disable-randomization.conf使用以下內容製作配置文件 ：

[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

然後重啟 NetworkManager.service

systemctl restart NetworkManager.service

（儘管我必須重新啟動才能使其工作。）
