我有一个非常奇怪的行为,在早上的某个时刻,即使连接符号亮着,我的 wifi 连接也会停止工作。如果我尝试重新连接到任何网络,我都无法做到这一点。我需要重新启动我的电脑才能使我的 WIFI 再次工作。奇怪的是,这种情况每天发生一次,通常发生在相同的时间左右。我真的不知道会是什么!我的笔记本电脑是 HP ZBook。
谢谢

根据@waltinator 和@karel 的建议,我所看到的是sudo journalctl

这看起来太像你的 ISP 在干扰你的路由器了,我很难相信这与 Ubuntu 有什么关系,但你的 ISP 为什么要干扰你的路由器呢?也许你的 ISP 已经注意到你的路由器存在奇怪的性能问题,这表明你的路由器可能有缺陷,所以他们干扰你的路由器是为了给你一个微妙的暗示,也许是时候换一个路由器了。
查看网络日志,看看还能找到什么。
sudo journalctl -b 0 -u NetworkManager
