我在 2015 年初使用 Broadcom BCM43602 wifi 芯片在 Macbook Pro 上安装了 CentOS 7。我已经通过挖掘有关 wifi 设置的 CentOS 文档尝试了所有其他方法。我终于意识到一个潜在的解决方案是为brcmfmac内核模块编译反向移植。
运行内核
Linux centos7.localdomain 3.10.0-327.13.1.el7.x86_64 #1 SMP Thu Mar 31 16:04:38 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
我做了什么
- 从https://www.kernel.org/pub/linux/kernel/projects/backports/stable/下载并解压后端口
- 阅读反向移植文档

make defconfig-brcmfmac跑
