答案1

这可能是驱动程序问题。您是否安装了r8168 RealTek 驱动程序？

sudo apt-get update

sudo apt-get install r8168-dkms

** 编辑 **

请注意，此驱动程序仅应用于内核驱动程序 r8169 尚不支持的设备。安装 r8168-dkms 软件包将禁用内核 r8169 模块。要重新启用 r8169，必须清除 r8168-dkms 软件包。

答案2

感谢所有回答我的问题的人，我用这个方法解决了我的问题：

如果安装了 r8168-dkms，请先删除：

user@linux:~$ sudo apt purge r8168-dkms

确保安装build-essential：

user@linux:~$ sudo apt-get install build-essential linux-headers-$(uname -r)

将 r8169 驱动程序列入黑名单：

user@linux:~$ sudo sh -c 'echo blacklist r8169 >> /etc/modprobe.d/blacklist.conf'

我用GBE 以太网 LINUX 驱动程序 r8168 适用于内核 5.6 及以上版本 (Unix(Linux))对于驱动程序，下载驱动程序后打开终端并找到文件：

user@linux:~$ cd /path/to/file

user@linux:~$ tar xfvj r8168-8.048.03.tar.bz2

user@linux:~$ cd r8168-8.048.03

最后一步：

user@linux:~$ sudo ./autorun.sh

lsmod | grep r8使用或检查驱动程序是否正常工作ethtool：

user@linux:~$ cd ethtool -i <your_logical_name>

为我：

user@linux:~$ cd ethtool -i enp3s0

输出：

driver: r8168
version: 8.048.03-NAPI
firmware-version: 
expansion-rom-version: 
bus-info: 0000:03:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no

然后重新启动。
