我经常会遇到奇怪的连接丢失问题：目前，大约每两分钟我就无法通过 wifi 建立连接，尽管 wifi 通知不会发出任何断开连接的信号。我编写了一个脚本来记录这些连接丢失的情况（测试大约每秒运行一次，只是测试是否可以访问 google.com）。以下是部分结果：

我已经运行了journalctl --follow，但它没有显示具有观察到的频率的条目。我已停用 IPv6 和 wifi 省电功能（如下所述：Ubuntu 18.04 LTS 上的 WiFi 随机断开连接）。该系统是一个相当新且未经修改的 Xubuntu 20.04 安装。使用旧版 Xubuntu 18.04 安装时，也出现了同样的问题。您知道潜在的问题可能是什么，以及如何调试甚至解决它吗？
