linux系统 BCM43142的网卡 安装

检查网卡驱动：

[paul@localhost ~]$ lspci |    grep Network
09:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43142 802.11b   /g/n (rev 01)

 安装依赖：

#e17
yum group  install 'Development Tools'
yum  install redhat-lsb kernel-abi-whitelists
yum  install -y kernel-headers kernel-devel
yum  install -y  gcc

建立rpmbuild目录 ：

mkdir -p ~ /rpmbuild/ {BUILD,RPMS,SPECS,SOURCES,SRPMS}
echo -e  "%_topdir $(echo $HOME)/rpmbuild\n%dist .el$(lsb_release -s -r|cut -d" . " -f1).local" >> ~/.rpmmacros

下载对应驱动：

wget http://elrepo.org/linux/elrepo/el7/SRPMS/wl-kmod-6_30_223_271-5.el7.elrepo.nosrc.rpm

 

编译：

#cp to rpmbuild/SOURCES/下
cp hybrid-v35_64-nodebug-pcoem-6_30_223_271. tar .gz ~ /rpmbuild/SOURCES/hybrid-v35_64-nodebug-pcoem-6_30_223_271 . tar .gz
#~/rpmbuild/RPMS文件夹下生成rpm文件
rpmbuild --rebuild --target=` uname -m` ~ /wl-kmod-6_30_223_271-5 .el7.elrepo.nosrc.rpm
#安装rpmbuild/RPMS/下kmod-wl包
yum remove \*ndiswrapper\*
sudo rpm -Uvh  ~ /rpmbuild/RPMS/x86_64/kmod-wl-6_30_223_271-5 .el7. local .x86_64.rpm
sudo modprobe wl   #加载驱动至内核
rm -rf rpmbuild   #删除包

最后安装：

yum   install -y NetworkManager   #网络管理工具
yum -y  install wpa_supplicant  #
