如何在Ubuntu 16.04上使用4.15.0-xx内核修复Broadcom驱动程序Wifi
我在Windows上为Broadcom网络适配器重新安装了一个驱动程序，之后我的WiFi完全停止在Ubuntu（16.04）上运行。
我尝试使用以下命令重新安装驱动程序：
1. sudo apt-get purge bcmwl-kernel-source 2. sudo apt-get install bcmwl-kernel-source 但它没有帮助
输出第二个命令（安装bcmwl-kernel-source）：
Unpacking bcmwl-kernel-source (6.30.223.271+bdcom-0ubuntu1~1.2) ... Setting up bcmwl-kernel-source (6.30.223.271+bdcom-0ubuntu1~1.2) ... Loading new bcmwl-6.30.223.271+bdcom DKMS files...

这个命令lspci -nn -d 14e4输出：
08:00.0 Network controller [0280]: Broadcom Limited BCM43142 802.11b/g/n [14e4:4365] (rev 01)
你能告诉我如何解决我的问题吗？

Canonical将Ubuntu 16.04的HWE堆栈更新到4.15内核。 但他们忘记更新Broadcom无线驱动程序，因此可以构建它。 这是一个关键且非常愚蠢的错误，会给许多使用LTS的人带来麻烦。
现在问题正在解决，并且已经构建了兼容的驱动程序版本
这个问题可以通过安装应该在4.15内核上构建的兼容版本的bcmwl-kernel-source来解决。
下载http://archive.ubuntu.com/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu1~1.3_amd64.deb
并使用dkpg安装它。
这可以通过
wget http://archive.ubuntu.com/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu1~1.3_amd64.deb sudo dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu1~1.3_amd64.deb
Windows根本不相关。
问题是你有一个与驱动程序不兼容的内核。
重要提示：如果除了Broadcom Wi-Fi之外没有任何其他网络连接，则可以使用grub菜单使用以前的内核启动并安装驱动程序。 它应该为所有内核构建。
Pilot6对这个问题很好的答案，它看起来像是xenial的官方修复（即不需要一个人从bionic安装包）已经发布（如果你使用包broadcom-sta ），或者已经提交（如果你使用包bcmwl它提供了bcmwl-kernel-source ）。
