我在用有线（以太网）在 ZFS 根目录上安装的 Ubuntu 22.04 LTS 上连接。需要说明的是，我的网卡根本不支持无线连接。当我启动 Ubuntu 或尝试使用命令“sudo shutdown now”或使用集成界面（在我的情况下是 KDE Plasma）上的关机按钮关机时 - 其他设备（如平板电脑、手机、笔记本电脑）会立即断开与我的 Wi-Fi 网络的连接，并且无法重新连接，直到我的机器上建立以太网为止。
（如果我尝试，sudo shutdown --poweroff now其他设备的 Wi-Fi 不会掉线）
这真的很奇怪，因为我已经尝试了一切方法来解决这个问题，绝对的一切，我已经重新安装了系统五次，现在我在这里问这个问题。
首先我想解释一下，用于使用 ZFS 文件系统进行系统安装我已经关注官方说明openZFS 文档。一切都应该没问题吧？其实不是，我注意到在重新安装系统后，出于某种原因一切都很好，直到你运行命令 apt dist-upgrade之后就会出现这个问题...
好吧，如果在处理后出现问题apt dist-upgrade 然后问题就出现了，因为升级了一些软件包？ 我试过列出并降级所有软件包在处理此命令后已升级，并且还是同样的问题。
我在故障排除时尝试过的解决方案：
- 22.04，wifi经常断线几秒钟| NetworkManager 中已禁用 powersave。
- https://ubuntuforums.org/showthread.php?t=2452472| 在 BIOS 电源管理中 - 设置“控制 WWAN 无线电”和“控制 WLAN 无线电”被禁用。
- 除非我先启动 Windows，否则 Wifi 会在重启后停止工作| 我没有双启动，但无论如何我已经检查过快速启动、安全启动（CSM）已被禁用。
一开始我以为这是 DHCP4 的问题，我尝试将我的网络服务从内部 DHCP 更改为 dhcpclient，结果仍然相同。然后我尝试设置静态 IP 而不是 DHCP 的动态 IP，结果仍然相同。
我也认为问题可能出在 NetworkManager 上，但即使转移到网络后问题仍然存在。
我也在 journalctl 中注意到了这条消息，我的网速是 100mbps 而不是 1gbps也许这就是问题所在？：
Generic FE-GE Realtek PHY r8169-0-200:00: Downshift occurred from negotiated speed 1Gbps to actual speed 100Mbps, check cabling!
8169 0000:02:00.0 enp2s0: Link is Up - 100Mbps/Full (downshifted) - flow control rx
我尝试通过关闭 rc.local 中的自动协商来修复此问题，但没有帮助。
当网络服务尝试建立我的以太网连接时，我还注意到 avahi-daemon 发出了这些奇怪的消息：
Jul 10 00:25:31 localhost avahi-daemon[1024]: Leaving mDNS multicast group on interface enp2s0.IPv6 with address fe80::c23f:d5ff:feaf:>
Jul 10 00:25:31 localhost avahi-daemon[1024]: Joining mDNS multicast group on interface enp2s0.IPv6 with address 2001:12:34:45:1:2:3:6.

Jul 10 00:25:31 localhost avahi-daemon[1024]: Withdrawing address record for fe80::c23f:d5ff:feaf:6ebd on enp2s0.
我尝试通过 * 来修复它关闭 avahi-daemon，因为我不想使用
在尝试修复此问题失败后，我想查看 journactl 在第二次启动（因为第一次启动是系统配置）和出现此问题的最新启动之间的差异。因此这里是：
第二次启动： https://pastebin.com/EpaByGpY
最新启动（有问题，并启用 networkd 的调试日志记录)： https://pastebin.com/jWkzEb2E
这真的很有趣，因为最新的启动日志中有消息：

这真的很奇怪。不仅仅是因为我已经禁用了 LLDP 客户端，而且由于某种原因它仍然启用，还因为 networkd 出于某种原因 3 次忘记了路由和 IP 地址，然后重试记住它们，为什么 networkd 会这样做？NetworkManager 也会发生这种情况。
我还注意到在 etc/systemd/network/ 中没有 .network 文件，也许这就是问题所在？我应该自己创建.network 文件吗？systemd-network-generator.service 不应该生成 .network 文件吗？
然后我发现了这篇文章：https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2024327 askubuntu.com 上有这个：Ubuntu 22.04LTS 中的 wifi 问题 以及其他有关 Wi-Fi 问题的帖子，其中唯一的解决方案就是安装另一个版本的内核：如何将我的内核更新到最新版本？ 22.04，wifi经常断线几秒钟 所以我认为问题出在我的内核上，我尝试了不同版本的主线内核，这是列表：
- 5.18（遇到同样的问题）
- 5.17.5（遇到同样的问题）
- 5.16（遇到相同问题）
- 5.15.20（遇到同样的问题）
- 5.15.0-76（已安装，遇到相同问题）
如果我尝试从 Ubuntu 22.04 LiveCD 启动有Wi-Fi 连接没有问题，Wi-Fi 不会在开机时关闭，一切正常。
如果我尝试从 Ubuntu 22.04 LiveCD 全新安装会有Wi-Fi 连接没有问题，所以也许你们会想——这是解决方案，只需重新安装系统从默认安装程序但没有遵循 openzfs 的文档，使用默认安装程序与通过默认安装程序安装系统相同。
我还注意到Ubuntu 22.04 LiveCD 使用内核版本 5.19，所以现在我正在考虑安装内核 5.19，我听说内核 5.19 发布，包含新的重大网络调整，那么也许我的问题有解决办法吗？最痛苦的是我可能会升级我的 zfs 文件系统版本以及我该如何做到这一点，这是另一个问题，因为没有关于此的文档或教程。 （我的 zfs 版本是 2.1.5，不支持内核 5.19 及更高版本）
我对此感到厌倦，实际上我已经尝试了一切，任何答案都将不胜感激。

答案1
您的网络配置看上去相当糟糕。
我们看到您的其他网络设备需要你的 Ubuntu 电脑为了获得互联网连接（尽管没有理由这样做）。您应该检查这些设备的配置。（我建议使用笔记本电脑，因为从那里收集信息可能更容易）
查看他们被分配了哪些 IP 地址、他们的网关、他们的 DNS 服务器以及跟踪路由显示的内容......
我怀疑您的计算机充当了 dhcp 服务器，可能将自己伪装成网关，并将流量重定向到路由器。这可以解释为什么计算机停机时其他设备会失去互联网连接。
至于直到才出现的错误apt dist-upgrade，那一定是在更新某个 dhcp 包，而该包要么最终以错误的方式进行自我配置，要么只是重新加载以以这种方式应用现有配置。
