Fedora BCM43142 无线网卡驱动安装

OS：Fedora 25 KDE

系统内核：4.10.16-200.fc25.x86_64 #1

网卡：BCM43142

1、识别自己的网卡型号：
命令：lspci | grep -i broadcom

或者 lspci | grep -i Network

03:00.0 Network controller: Broadcom Limited BCM43142 802.11b/g/n (rev 01)

2、添加源：添加RPM Fusion源 安装需要的包
yum install --nogpgcheckhttp://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-25.noarch.rpm

3、安装

$ yum search kmod-wl
Redirecting to '/usr/bin/dnf search kmod-wl' (see 'man yum2dnf')

====================================== N/S 匹配：kmod-wl =======================================

kmod-wl.x86_64 : Metapackage which tracks in wl kernel module for newest kernel

akmod-wl.x86_64 : Akmod package for wl kernel module(s)

kmod-wl-4.10.16-200.fc25.x86_64.x86_64 : wl kernel module(s) for 4.10.16-200.fc25.x86_64

$ yum install akmod-wl kmod-wl  
sudo dnf install kernel-devel akmod-wl 　　   　　重新编译内核模块
sudo akmods 　　　　　　　　　　　　　　　　加载内核代码
sudo modprobe wl 　　　　　　　　　　　　　　重启网络管理器
sudo systemctl restart NetworkManager

如果源里也没有，只能自己下载安装，这里可以到http://rpmfind.net去搜索下载，或者：http://pan.baidu.com/s/1eSKEEDc，是rpm包，下下来安装，然后又会报这个akmods包依赖rpmdev-vercmp 和kmodtool，那就安装：
yum install rpmdevtools -y

去http://rpmfind.net搜索kmodtool下载安装，或者：http://pan.baidu.com/s/1jI8vnHs
完成后再安装akmods，这回应该就过了。过了以后就可以运行：
yum install kmod-wl -y
