我并没有真正尝试重现该问题，但它似乎在某种形式的流媒体发生时发生。最终我通过 Realtek RTL8723AE 失去了无线连接。这可能需要几个小时。
启用/禁用 WiFi 和/或网络并重新连接失败。我收到以下警告sudo service network-manager status：
错误：无法打开/run/network/ifstate
重新启动network-manager服务没有影响。我通常只是重新启动，但想确定问题的根本原因。我读了一些资料，但还没有从我的搜索中找到解决方案。
我也尝试过sudo iplink set wlp4s0 up，结果
RTNETLINK 回答：由于 RF-kill，无法进行操作
nmcli networking on; nmcli radio wifi on没有效果...操作系统继续尝试连接然后说连接丢失。
我在 Ubuntu 16.0.4 和我的新 Lubuntu 安装 19.0.4（同一台笔记本电脑）上遇到了同样的问题。从 Windows 启动时，WiFi 适配器 Realtek RTL8723AE 没有任何问题。

我确实在网上看到了一些东西，但还没有尝试过，因为我不确定这些选项的工作原理：
