安装CentOS7后网卡不能识别

悬赏园豆：10 [待解决问题]

新安装了个CentOS，结果装完了之后网卡不能识别，使用lspci命令查看能输出主板信息，ifconfig -a 命令却不能看到主板的网卡，只能看到我的USB无线网卡信息。怎么半呢？

看样子应该是能识别网卡的啊，怎么就是不能用呢？

请发下 lspci -vvv 和 lsmod 的标准输出

Kimmin | 园豆：88 (初学一级) | 2015-10-21 00:29

已经补充了下问题，把lspci -vvv 和 lsmod 的标准输出的标准输出打印出来了，大神给看看，先谢了。

@fengbohello: 没有驱动模块你的这网卡应该是安装CENT的时候还没有插入PCI槽（总之没有被主板BIOS识别）所以没有安装网卡驱动，办法:

1. 换台主机在官方网站可以下载对口的网卡驱动，具体按照请参考包中的makefile文件

2. 确认lspci有识别网卡后，重新安装操作系统

@Kimmin: 我目前的机器是win7和centos双系统，切换到win7可以正常识别网卡。网卡是集成的，应该不存在没有插入pci槽的情况。我重新安装系统试试吧。

@Kimmin: 我下载了CENTOS7的everything版，用U盘启动，在U盘启动后查看网络设置，依然无法发现网络设备。上次的系统是64位的ubuntu，是可以发现网卡设备的。所以应该是centos7目前没有设个网卡设备可用的驱动。唉……

如果是192.168.10.136这个网卡，应该是正常的，其RX TX都在传送包了，估计是系统防火墙啥的开了吧,造成访问不了这个机器

2012 | 园豆：21645 (高人七级) | 2015-10-26 10:36

10.136是我的无线网卡。我的主板上的网卡没有识别。

@fengbohello: 现在windows下用驱动之家等看看内置网卡的芯片型号，一般都是intel的，在对应的官网下载网卡驱动，自己安装一下看看【需要编译安装的】

从你的pci上可以看到，并没有识别wifi设备。

可以在dmesg 查看是否有intel wifi相关设备信息。

首先、intel iwl系列的无线网卡驱动分为两部分：驱动+固件。

看到你lsusb，请问是USB网卡还是PCIe的无线网卡？
首先保证硬件设备被检测到，再解决驱动是否存在的问题。

Centos 7 发行版默认包含iwl驱动的，固件也应该包含，请提供你网卡型号。

你可以从两个部分部分入手：第一、确认是否包含驱动（应该以模块的方式存在b/moudle/kernel_version/deriver/的按个目录下）；第二：是否包含固件（在/firmware/目录下）
