Centos编译安装博通无线网卡BCM43XX驱动

https://wiki.centos.org/HowTos/Laptops/Wireless/Broadcom

前言

CentOS 7本身可以支持很多常见的无线网卡，但如果你不幸使用了博通公司的BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM43224, BCM43225, BCM43227 and BCM43228这些型号的无线网卡，就需要进行一些配置了。

注：本文所记录的方法主要针对EL6 and EL7

目录

  • 步骤一：确定无线网卡型号，并安装依赖包
  • 步骤二：下载、解压博通无线网卡驱动压缩包
  • 步骤三：编译博通芯片驱动模块
  • 步骤四：将驱动载入内核
  • 步骤五：将驱动载入程序加入开机启动

步骤一：确定无线网卡型号，并安装依赖包

**

[user@host ~]$ /sbin/lspci | grep Broadcom  
0b:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 01)

注：博主自己电脑网卡的型号是BCM43142，虽然原帖中没有列出来，也是没有关系的，方法完全适用

另外确定你在之后编译阶段没有缺失必要的宏包

**

[root@host ~]# yum install kernel-headers kernel-devel gcc

当然啦，如果你用的是服务器，要编译 Xen kernel (i.e. kernel-xen)，那你需要下载 kernel-xen-devel 而不是 kernel-devel。

步骤二：下载、解压博通无线网卡驱动压缩包

从博通官网下载BCM43xx linux驱动包，并且解压到 /usr/local/src/hybrid-wl

64位：

https://docs.broadcom.com/docs-and-downloads/docs/linux_sta/hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz

32位：

https://docs.broadcom.com/docs-and-downloads/docs/linux_sta/hybrid-v35-nodebug-pcoem-6_30_223_271.tar.gz

更新：这里直接将所有需要下载的文件都打包上传上来：

bcm4352src.zip

列了这么多，其实只需要根据情况下载第一个或者第二个就可以了。

**

[root@host ~]# mkdir -p /usr/local/src/hybrid-wl  
[root@host hybrid-wl]# cd /usr/local/src/hybrid-wl  
[root@host hybrid-wl]# tar xvfz /path/to/the/tarball/hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz  
[root@host hybrid-wl]# chown -R someuser.somegroup /usr/local/src/hybrid-wl

步骤三：编译博通芯片驱动模块

**

[user@host hybrid-wl]$ make -C /lib/modules/`uname -r`/build/ M=`pwd`

根据目前这个版本的驱动，几乎可以肯定所有人都会编译出错，在CentOS 6上你会看到如下的情况：

**

make: Leaving directory `/usr/src/kernels/2.6.32-573.7.1.el6.x86_64'

接下来就是el6和el7步骤不同的地方

EL6

在EL6上，因为内核中 if-then-els语句会搜寻**wl_cfg80211_hybrid.**这个文件，为了修正这个问题，我们运行以下语句：

**

[user@host hybrid-wl]$ sed -i 's/[ >][>=] KERNEL_VERSION(2, 6, 3.)/>= KERNEL_VERSION(2, 6, 32)/' src/wl/sys/wl_cfg80211_hybrid.c  
[user@host hybrid-wl]$ sed -i 's/[ >][>=] KERNEL_VERSION(3, ., .)/>= KERNEL_VERSION(2, 6, 32)/' src/wl/sys/wl_cfg80211_hybrid.c  
[user@host hybrid-wl]$ sed -i 's/[ >][>=] KERNEL_VERSION(3, 11, .)/>= KERNEL_VERSION(2, 6, 32)/' src/wl/sys/wl_cfg80211_hybrid.c  
[user@host hybrid-wl]$ sed -i 's/< KERNEL_VERSION(3, 18, .)/< KERNEL_VERSION(2, 6, 30)/' src/wl/sys/wl_cfg80211_hybrid.c  
[user@host hybrid-wl]$ sed -i 's/[ >][>=] KERNEL_VERSION(3, 15, .)/>= KERNEL_VERSION(2, 6, 32)/' src/wl/sys/wl_cfg80211_hybrid.c  
[user@host hybrid-wl]$ sed -i 's/[ >][>=] KERNEL_VERSION(4, 0, 0)/>= KERNEL_VERSION(2, 6, 32)/' src/wl/sys/wl_cfg80211_hybrid.c  
[user@host hybrid-wl]$ sed -i 's/< KERNEL_VERSION(4,2,0)/< KERNEL_VERSION(2, 6, 30)/' src/wl/sys/wl_cfg80211_hybrid.c

EL7

而在EL7上，需要运行的是以下语句：

**

[user@host hybrid-wl]$ sed -i 's/ >= KERNEL_VERSION(3, 11, 0)/ >= KERNEL_VERSION(3, 10, 0)/' src/wl/sys/wl_cfg80211_hybrid.c
[user@host hybrid-wl]$ sed -i 's/ >= KERNEL_VERSION(3, 15, 0)/ >= KERNEL_VERSION(3, 10, 0)/' src/wl/sys/wl_cfg80211_hybrid.c

[user@host hybrid-wl]$ sed -i 's/ < KERNEL_VERSION(3, 18, 0)/ < KERNEL_VERSION(3, 9, 0)/' src/wl/sys/wl_cfg80211_hybrid.c
[user@host hybrid-wl]$ sed -i 's/ >= KERNEL_VERSION(4, 0, 0)/ >= KERNEL_VERSION(3, 10, 0)/' src/wl/sys/wl_cfg80211_hybrid.c

[user@host hybrid-wl]$ sed -i 's/ < KERNEL_VERSION(4,2,0)/ < KERNEL_VERSION(3, 9, 0)/' src/wl/sys/wl_cfg80211_hybrid.c
[user@host hybrid-wl]$ sed -i 's/ >= KERNEL_VERSION(4, 7, 0)/ >= KERNEL_VERSION(3, 10, 0)/' src/wl/sys/wl_cfg80211_hybrid.c

[user@host hybrid-wl]$ sed -i 's/ >= KERNEL_VERSION(4, 8, 0)/ >= KERNEL_VERSION(3, 10, 0)/' src/wl/sys/wl_cfg80211_hybrid.c

[user@host hybrid-wl]$ sed -i 's/ >= KERNEL_VERSION(4, 11, 0)/ >= KERNEL_VERSION(3, 10, 0)/' src/wl/sys/wl_cfg80211_hybrid.c
[user@host hybrid-wl]$ sed -i 's/ < KERNEL_VERSION(4, 12, 0)/ < KERNEL_VERSION(3, 9, 0)/' src/wl/sys/wl_cfg80211_hybrid.c
[user@host hybrid-wl]$ sed -i 's/ >= KERNEL_VERSION(4, 12, 0)/ >= KERNEL_VERSION(3, 10, 0)/' src/wl/sys/wl_cfg80211_hybrid.c
[user@host hybrid-wl]$ sed -i 's/ <= KERNEL_VERSION(4, 10, 0)/ < KERNEL_VERSION(3, 9, 0)/' src/wl/sys/wl_linux.c

Hunk #3 succeeded at 2450 (offset 3 lines).
Hunk #4 succeeded at 2466 (offset 3 lines).

打补丁，再次编译

以下步骤在EL6和EL7上相同。

下载wl-kmod-fix-ioctl-handling.patch到 /usr/local/sr并运行

**

[user@host hybrid-wl]$ patch -p1 < ../wl-kmod-fix-ioctl-handling.patch  
patching file src/wl/sys/wl_cfg80211_hybrid.c  
Hunk #1 succeeded at 1467 (offset 17 lines).  
patching file src/wl/sys/wl_linux.c  
Hunk #1 succeeded at 1659 (offset 8 lines).

现在再次编译

**

[user@host hybrid-wl]$ make -C /lib/modules/`uname -r`/build/ M=`pwd`

这次我们得到的输出应该是这样：

**

make: Entering directory `/usr/src/kernels/2.6.32-573.7.1.el6.x86_64'

make: Leaving directory `/usr/src/kernels/2.6.32-573.7.1.el6.x86_64'

之后可以去掉一些不必要的符号

**

[user@host hybrid-wl]$ strip --strip-debug wl.ko

至此，驱动已经编译完成，可以使用。

步骤四：将驱动载入内核

首先，移除已经存在的一些不可用的无线网卡驱动，这样才能载入新的。

**

[root@host ~]# modprobe -r bcm43xx  
[root@host ~]# modprobe -r b43  
[root@host ~]# modprobe -r b43legacy  
[root@host ~]# modprobe -r ssb  
[root@host ~]# modprobe -r bcma  
[root@host ~]# modprobe -r brcmsmac  
[root@host ~]# modprobe -r ndiswrapper

把驱动模块放在kernel能找到的地方

**

[root@host hybrid-wl]# cp -vi /usr/local/src/hybrid-wl/wl.ko /lib/modules/`uname -r`/extra/

然后运行

**

[root@host ~]# depmod $(uname -r)  
[root@host hybrid-wl]# modprobe wl

如果没有报错就可以用啦。

步骤五：将驱动载入程序加入开机启动

编辑 /etc/modprobe.d/blacklist.conf添加以下语句

**

blacklist bcm43xx  
blacklist b43  
blacklist b43legacy  
blacklist bcma  
blacklist brcmsmac  
blacklist ssb  
blacklist ndiswrapper

编辑 /etc/sysconfig/modules/kmod-wl.modules写入以下内容

**

#!/bin/bash  
for M in lib80211 cfg80211 wl; do   
  modprobe $M &>/dev/null  
done

这样，驱动就会开机启动啦！
