我第一次设置 ubuntu 服务器，遇到了一个奇怪的问题。
基本上，当我插入以太网电缆时，对终端命令的响应会变得非常慢。
例如：插入电缆时“sudo nano /etc/ufw/before.rules”命令需要几秒钟才能打开，但拔下电缆时会立即打开。
这种延迟几乎在任何命令中都会发生，但当我断开以太网电缆时就会得到修复。
我已启用 ufw，并将其配置为拒绝除我的 SSH 端口之外的所有传入连接，同时允许所有传出连接。
该机器本身曾经是一台 Windows 机器，但我只在连接的新驱动器上安装了全新安装的 ubuntu 服务器。我使用的是直接插入塔式机的键盘。
有人知道我该如何解决这个问题吗？我尝试用谷歌搜索，但没有找到与此延迟相关的任何内容，因为延迟与我输入的单个字符无关。
感谢所有的帮助！
编辑 1：即使我禁用 ufw，问题仍然存在。

编辑4：我正在努力从英特尔网站获取以太网驱动程序（https://downloadcenter.intel.com/download/13663），但我无法使用apt-get install linux-headers-$(uname -r)该页面的命令（https://www.intel.ca/content/www/ca/en/support/articles/000005480/network-and-io/ethernet-products.html）有什么提示或文件可以帮助我更好地理解这一点吗？
编辑 5：我已经下载了驱动程序，但现在正在尝试解压它，但收效甚微
编辑 6：原来我正在将 html 下载到重定向到下载链接的页面。以防将来有人需要知道，命令“文件”会告诉您文件类型指定的文件$ file filename.tar
我正在按照此处的说明进行操作：https://www.intel.ca/content/www/ca/en/support/articles/000005480/network-and-io/ethernet-products.html
编辑 7：好吧，我想我按照说明安装了英特尔以太网驱动程序，但系统的行为没有任何区别。启动终端命令后仍有 5-10 秒的延迟
编辑 8：我暂时放弃了，刚刚切换到 Ubuntu 桌面。一旦我完成所有设置并从那里开始，我将禁用 GUI 驱动程序
