2025年Ubuntu 18.04 安装网卡驱动（有线连接）

大家好，我是讯享网，很高兴认识大家。

之前一直用小米的驱动，但是感觉太慢了，所以还是决定使用有线连接。

但是之前进入Linux系统后，有线连接没有，所以需要安装驱动。

01 查询网卡类型（Windows）

进入windows系统，进入CMD命令行，输入systeminfo
查询网卡类型

网卡: 安装了 2 个 NIC。 [01]: Realtek PCIe 2.5GbE Family Controller 连接名: 以太网 2 启用 DHCP: 是 DHCP 服务器: 10.193.0.1 IP 地址 [01]: 10.193.194.9 [02]: fe80::9b6:1e28:e575:69cd [03]: 2001:da8:1002:8040::2:939c [02]: Xiaomi 802.11n USB Wireless Adapter 连接名: WLAN 2 状态: 媒体连接已中断

02 查询网卡驱动（Ubuntu）

在 Ubuntu打开终端，输入lspci -v 查看网卡驱动

如果末尾显示：Kernel driver in use:r8169

说明驱动版本不符，需要重新安装驱动，要安装RTL8125

选择安装RTL8125，是根据windows查询到的网卡类型选择的

查询结果如下：

在这里插入图片描述

03 Ubuntu下安装驱动

进入官网

https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software

选择Linux下的 r8125 进行安装
在这里插入图片描述

下载下来的文件名为：r8125-9.007.01.tar.bz2

将此文件右键解压缩，然后把压缩文件复制到想要安装的位置

然后进入此目录下，运行以下指令

cd ~/software/r8125-9.007.01 sudo chmod +x autorun.sh sudo ./autorun.sh

运行结果如下：

讯享网guyue@guyue:~/software/r8125-9.007.01$ sudo chmod +x autorun.sh [sudo] guyue 的密码： guyue@guyue:~/software/r8125-9.007.01$ sudo ./autorun.sh Check old driver and unload it. rmmod r8169 Build the module and install At main.c:160: - SSL error:0:system library:fopen:No such file or directory: ../crypto/bio/bss_file.c:72 - SSL error:2006D080:BIO routines:BIO_new_file:no such file: ../crypto/bio/bss_file.c:79 sign-file: certs/signing_key.pem: No such file or directory Warning: modules_install: missing 'System.map' file. Skipping depmod. Backup r8169.ko rename r8169.ko to r8169.bak DEPMOD 5.4.0-90-generic load module r8125 Updating initramfs. Please wait. update-initramfs: Generating /boot/initrd.img-5.4.0-90-generic Completed.

安装完后运行以下指令，更新软件

sudo apt-get update sudo apt-get install ubuntu-make

04 后续问题解决

电脑重启以后，网络有线连接又没有了，然后重新运行下述代码，网络有限连接就又有了

讯享网cd ~/software/r8125-9.007.01 sudo chmod +x autorun.sh sudo ./autorun.sh
