经常、间歇性断网。网络管理员似乎对此负有责任

每隔几分钟（范围从 5 到 30 分钟），我就会失去互联网连接。这似乎与以下 journalctl 条目相吻合：

manager: NetworkManager state is now CONNECTED_SITE

重新启动 NM 可暂时修复连接，并反映在 journalctl 中：

manager: NetworkManager state is now CONNECTED_GLOBAL

有时 NM 会自行修复，但随后不久就会中断，如以下 journalctl 条目所示，这是迄今为止我发现的有关此问题的唯一日志。

我已经按照相关帖子中的说明在 /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf 中调整了省电模式，但没有成功。
