BCM43228 自内核 3.15.xx 起不再工作

BCM43228 自内核 3.15.xx 起不再工作

从那时起yum update，我的 WiFi 就断开了。该命令rfkill list返回：

0: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no

我发现我必须这样做，rmmod hp-wmi并且我做到了，并且在执行此操作后软（在上面的输出中看到）没有被阻止，但问题仍然存在。

细节：

我需要去做ifconfig wlo1 up。不管怎样都行不通。

该命令dmesg | grep wl返回：

[    7.751232] wl: module license 'MIXED/Proprietary' taints kernel.
[    7.801938] systemd-udevd[494]: renamed network interface eth0 to wlo1

想法#1

我首先尝试获取最新的 Broadcom 驱动程序，可在此处获取：

想法#2

也许这篇博文是您的问题？标题：Broadcom Wireless 无法在 Fedora 20 Kernel 3.15 上运行。它详细介绍了 2 个错误，详细信息请参见此处：

以及 Gentoo bug tracker 中详细介绍的补丁：

$ curl https://513156.bugs.gentoo.org/attachment.cgi?id=378836 -o patch.txt

本博客文章的其余步骤如下：

摘抄

我抓住了机会，将其直接应用到/tmp/wifi.补丁成功并且模块编译。

$ sudo yum install patch
$ cd /tmp/wifi && patch -p1 < patch.txt

接下来，我需要将模块复制到 . 搜索的默认模块文件夹中modprobe。

$ sudo mkdir /lib/modules/`uname -r`/extra/net/wireless
$ sudo cp wl.ko /lib/modules/`uname -r`/extra/net/wireless
$ sudo depmod -a

接下来删除可能与此冲突的任何其他软件和驱动程序。就我而言，这意味着删除 Broadcom OpenFWWF 软件包并删除 bcma 内核模块并将其列入黑名单。

$ sudo rmmod bcma
$ sudo echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf
$ sudo yum remove b43-openfwwf.noarch

要使用安装新模块modprobe

$ sudo modprobe wl

为了在启动时加载模块，我只需运行

$ sudo echo modprobe wl >> /etc/rc.local

最后使用 NetworkManager 配置新设备。哦，还要感谢我的前同事 Steve 提供的笔记本电脑；-)
