我最近几天都遇到了这个问题 - 不用说它有多烦人！当我重新启动笔记本电脑时，连接似乎在前几秒钟（大约 < 1/2 分钟）正常工作，但随后工具栏上的 wifi 图标变为？并且所有互联网连接都断开了（我也无法访问路由器页面）。
我正在运行 Ubuntu 18.04 与 Windows 10 双启动，并且 Wi-Fi 似乎在 Windows 上运行正常，因此似乎不是某种硬件问题。
更新：输出dmesg | tail -30

更新 2：我正在使用的蓝牙设备似乎受到干扰。最近我连接了 Apple 键盘，问题就是从那时开始出现的。现在我关闭了蓝牙，重新启动了 wifi，然后又可以正常工作了。我还应该在这里指出，我的蓝牙扬声器目前已连接，但没有造成任何问题。只有 Apple 键盘会造成问题。:S
这是新日志：

答案1
如果没有任何效果，我建议阅读描述这里特别注意 Docker：Docker 网络（网桥）配置实际上可能处于冲突国家与主机网络，如这个 Docker 论坛。如果您认为这是您的情况，则可能的修复方法是打开终端并执行以下命令：
docker network prune
正如选项所暗示的那样，这将删除至少一个容器未使用的所有自定义网络。
答案2
因此，显然正如我在编辑中提到的那样，我的问题源于 Apple 蓝牙键盘和我的 wifi 之间的干扰。更改路由器的频道或频率（2.4/5GHz）没有帮助。
解决问题的方法是重新配对蓝牙键盘，但不是通过 GUI。相反，我使用了提供的指南这里现在它运行完美！
