在CentOS7.6上为网卡BCM43228安装驱动

Posted on 2019-05-02 In Linux , CentoS

前言

前段时间给笔记本换了一块网卡，随便买了一块博通的BCM43228，然后在装centos的时候就翻车了，网上找的教程有不完善的地方，反复弄了好几次，终于弄好了，在这里整理一下过程。

参考

CentOS7 Broadcom无线网卡驱动安装
 安装CentOS 7双系统（四）——解决博通无线网卡问题
 以 Broadcom Corporation BCM4311, BCM4312, BCM4313, BCM4321, BCM4322, BCM43224, BCM43225, BCM43227 和 BCM43228 为基础的无线网络卡

环境

系统：centos7.6
内核：3.10.0-957.el7.x86_64

准备工作

安装编译器

yum install kernel-headers kernel-devel gcc

下载驱动

从博通官网的驱动中找到Linux® STA 64-bit driver下载

下载改代码脚本

由于这个驱动里面有不适配centos7.6的地方，所以需要通过脚本改一部分代码。将这个链接中的全部脚本下载待用（虽然有一个并不会用到）

编译

执行以下命令

tar -xvf hybrid-v35_64-nodebug-pcoem-6_30_223_271.tar.gz
patch -p1 < ./wl-kmod-fix-ioctl-handling.patch
patch -p1 < ./wl-kmod-01_kernel_4.7_IEEE80211_BAND_to_NL80211_BAND.patch
patch -p1 < ./wl-kmod-02_kernel_4.8_add_cfg80211_scan_info_struct.patch
patch -p1 < ./wl-kmod-03_fix_kernel_warnings.patch
patch -p1 < ./wl-kmod-04_kernel_4.11_remove_last_rx_in_net_device_struct.patch
patch -p1 < ./wl-kmod-05_kernel_4.12_add_cfg80211_roam_info_struct.patch

如果执行正确，输出大致如下：

注意Hunk的数量以及是否succeed
在执行以下命令

然后再make就好，正常输入大致如下，会有一个warning

将驱动模块装入内核中

先卸载一些模块

modprobe -r bcm43xx
modprobe -r b43
modprobe -r b43legacy
modprobe -r ssb
modprobe -r bcma
modprobe -r brcmsmac
modprobe -r ndiswrapper

将驱动模块的文件复制到一个可以让内核找到它的地方：

cp -vi /usr/local/src/hybrid-wl/wl.ko /lib/modules/`uname -r`/extra/

这样做是为了与其它已经／将会从 kmod 组件安装的外置模块（例如：fuse、ntfs-3g、等）保持一贯性。
按著，执行：

depmod $(uname -r)

以便能创建一个模块的互赖性清单。现在我们装入驱动模块：

insmod wl.ko

假如这一步失败了并伴有如下提示信息：

insmod: error inserting 'wl.ko': -1 Unknown symbol in module

首先尝试创建模块依赖：

depmod `uname -r`

然后装入驱动模块：

modprobe wl

检查

iw dev

应该就有网卡出来了

设置开机时将驱动模块装入内核中

这一步使用参考资料中的方法似乎对于我的环境无用，所以我改成了鞋开机启动脚本的形式，开机启动脚本如下

modprobe -r bcma # 因为我的centos只有这一个碍事的脚本
modprobe -r wl # 不知道为啥必须要先卸载掉
depmod `uname -r`
modprobe wl

开机自动连接wifi

再在启动脚本中添加如下内容

ip link set dev wlp3s0 up
systemctl start network-manager.service
nmcli dev wifi connect "WIFI SSID" password "WIFI PASSWORD"
dhclient wlp3s0 up

非常迷的是，貌似是因为network-manager升级了之后，就无法使用了，即使命令变成了systemctl start NetworkManager.service
会出现内核级别的网卡报错wlp3s0 scan_results error -22
我屈服了……放弃了……
