我使用千兆字节 b550 游戏 x 主板构建了我的 detain 11 家庭服务器。该板上有一个 Realtek RTL8111/8168/8411 Lan 芯片。我家里到处都是 6A 类电缆，到处都可以使用 1000Mb/s 的互联网速度。
但是当我将服务器连接到以太网时，速度测试显示我的互联网速度为 +/- 95 Mb/s。即使我使用与 Windows 计算机相同的互联网电缆，速度通常为 +/- 800 Mb/s。
看起来速度被限制在100Mb/s。
我尝试直接使用安装固件-realtek 和 realtek 来安装驱动程序。
sudo apt-get list firmware-realtek
我已经做了一些谷歌搜索，这不是一个新问题。但我无法找到任何解决方案。有人为我应该运行这个命令而感到难过。但在该命令之后，我的服务器无法连接到网络。

人们可能知道我该如何解决这个问题吗？
