在我们的办公室运行各种 Windows、MAC 和 Ubuntu 机器。一切运行良好，直到今天早上，其中 3 台 Ubuntu 机器都显示没有网络，但以太网电缆（和 Wifi）设置自上周五以来一直没有改变。
今天早上连接有点乱，一点也不开心。它们都显示Connection failed Activation of network connection failed。我可以理解周末有一个出现故障，但 3 个呢？而且 Wifi 和以太网都出现故障。
抓起 USB 并从全新下载的 23.04 启动并遇到了同样的问题 - 这发生在两台不同的机器上。
重新格式化了其中一台机器，安装了 23.04，问题依旧。在另一台机器上尝试了全新的“试用 Ubuntu”，问题依旧。
我已经使用 Ubuntu 10 多年了，从来没有遇到过这样的事情 - 有什么建议吗？我知道可能是更新导致了这个问题，但是 23.04 的新副本肯定可以解决这个问题？
最后 - 这可能是误报，但周末我们注意到 Synology 盒子隔离了一个标记为Unix.Malware.Kaiji-10003916-0 - prometheus
Windows 和 MAC 机器运行良好，并且 2 台运行 22.04 和 20.04 的 Ubuntu 机器运行良好......

答案1
user535733 - 我读了你的评论，然后立即继续，因为不可能是路由器的问题，因为其他机器都很好。昨天遇到了一个稍微不同的问题，重启了路由器，现在一切都正常了。唉。忙着修复这个问题，因为它一定很复杂，你知道吗？:-)
