几个星期以来，我无法连接到 wifi 网络。当我尝试连接到任何 wifi 网络时，屏幕顶部的图标可以工作，但不会要求输入安全密钥；但是，当我连接到在 Firefox 中要求输入安全密钥的 wifi 网络时，它可以工作！......
我尝试了 Journalctl -f 命令，输出是
enter code Activation: (wifi) access point 'Livebox-0b18' has security, but secrets are required.

我也尝试重新启动 wpasupplicant 并得到以下结果：
wpa_supplicant[3276]: Successfully initialized wpa_supplicant
wpa_supplicant[3276]: dbus: wpa_dbus_get_object_properties: failed to get object properties: (none) none
wpa_supplicant[3276]: dbus: Failed to construct signal
wpa_supplicant[3276]: Could not read interface p2p-dev-wlan0 flags: No such device``
当我编辑连接时，它有效了！.....
