18.04 版有线连接速度慢(10 Mb/s)

我在使用 Intel I211 千兆网络连接的 Ubuntu 18.04 上遇到了非常慢的以太网连接。使用不同的 Ubuntu PC(具有不同的以太网控制器),相同的端口/电缆可以达到 100 Mb/s。输出为lspci -knn | grep Eth -A3

    Subsystem: Gigabyte Technology Co., Ltd I211 Gigabit Network Connection [1458:e000]
    Kernel driver in use: igb
    Kernel modules: igb

输出自ethtool enp4s0

当我将自动协商设置为开启时,它默认为半双工,速度约为 7 Mb/s(上传),将自动协商设置为关闭并全双工,我得到 12 Mb/s

我不知道如何解决这个问题,非常感谢任何帮助。
