出于某种原因，只要我持续 ping 到 Google 或 Bing 之类的东西，甚至是我的网络网关，就不会出现问题whoopsie，并且可以继续按预期使用我的设备。当我关闭 ping 时，网络连接会在大约 30 分钟后断开，情况会有很大变化。

我不确定还要搜索或显示什么信息，所以请告诉我，我会进行编辑。

答案1

根据参考：https://gist.github.com/okapies/de0d08f9e3c8bcb2b76a33b68f62a48c

这可能是内核问题：

尝试重新安装当前的 linux-header

我希望这能解决你的问题。

答案2

无线网卡进入睡眠状态

为了节省电量，许多 wifi 卡会进入睡眠状态以节省电量。在某些情况下，卡不会从睡眠状态唤醒：16.04 LTS wifi 连接问题

总结一下已接受的答案中的解决方案：

  1. 运行以下命令获取 PCI 无线网卡的详细信息sudo lshw -class network

  2. 根据产品线获取您的卡型号信息。例如，正如您在问题描述中看到的， product: RTL8723BE PCIe Wireless Network Adapter我的卡型号是RTL8723BE

    或产品：RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller 所以我的卡的型号是RTL8101/2/6E

  3. 给予许可sudo chmod 755 /etc/pm/config.d/

  4. 打开或创建config并添加SUSPEND_MODULES="rtl8723be"（替换rtl8723be为您自己的型号）

  5. 然后运行 echo "options rtl8723be fwlps=N" | sudo tee /etc/modprobe.d/rtl8723be.conf

  6. 最后重新启动系统。
