Ubuntu 22.04 激活网络连接失败

Question

我已经尝试了所有我发现的方法，但没有任何效果。

\n

我尝试使用的连接是有线以太网，电缆连接到墙壁插座，返回到 tp-link tl-sg108，它从 TIM HUB+ ZTE H388X 获取连接。\n该系统是双启动系统， Windows 10，它在那里工作得很好，不过，不确定这是否只是巧合，当我在 Ubuntu Steam 上停止工作后第一次切换回来时，警告它的服务没有运行，我必须将其设置为自动加载启动时。之后我回到 Ubuntu，尝试了一系列修复，但没有任何效果，我恢复了更改，重新启动，它再次工作，直到我切换回 Windows 并回到 Ubuntu，从那以后就没有工作了。\n每次我去回到Windows，时间倒退了2小时，我需要禁用并重新启用自动时间，Ubuntu自行管理它，除了现在它没有连接，所以例如在grep中syslog有一些比后来的一些条目提前了 2 小时，因为我注意到晚上 11 点后的某个时间点时间已经关闭。\n主板是 Asus Sabertooth Z87，因此网卡是 I217-V。\n连接在 Ubuntu 上工作了几周，工作正常，今天才开始不工作。

\n

在路由器上我尝试过：

\n

\n
• 重新启动，以便重置 DHCP 租约，以防租约仅适用于 Windows（如果是在 Windows 中获得的）
\n

\n

在 Windows 上我：

\n

\n
• 禁用快速启动；
\n
• 禁用网络唤醒；
\n

\n

在 Ubuntu 上我尝试过：

\n

\n
• 通过设置为 true 告诉 NetworkManager 管理所有连接\n在/etc/NetworkManager/NerworkManager.conf;
\n
• 在同一文件中设置 dhcp 客户端，包括内部、dhclient、dhcpcd；
\n
• netplan 有一行告诉它让 NetworkManaged 处理它的事情 in\n /etc/netplan/01-network-manager-all.yaml；
\n
• 使用sudo service NetworkManager restart和重新启动 NetworkManagessudo systemctl restart NetworkManager
\n
• 在\n处创建一个空文件/etc/NetworkManager/conf.d/10-globally-managed-devices.conf；
\n
• 手动设置IP、掩码、网关；
\n
• /var/lib/dhcp/dhclient.leases是空的;
\n
• /var/lib/dhcpcd只有无线 dhcp 租用文件和\nsecret文件；
\n

\n

通过运行，sudo dhcpcd -T eno1我有时看到它成功地获取了 IPv6，它实际上用于连接，但只不过是说它已连接。Ping 没有得到回复，并且在 ping 后检查 arp 只显示<incomplete>在地址中，这意味着它没有得到回复。\ndhclient 也挂起。

\n

我还没有尝试过：这个家伙没有明确解释他做了什么Can't get IP via DHCP in 19.04, but can't get IP via DHCP in 19.04, buttaining if I use Windows

\n

现在是常用的命令输出

\n

sudo lshw -C network

systemctl status NetworkManager（我最后手动禁用了连接，以免干扰 USB wifi）
