问题描述
因此，我尝试使用 dual-boot OS X 10.8.5(本机操作系统)和 Ubuntu 14.04。\n我安装了 Ubuntu(万岁！)，但启动到 Ubuntu 后，我发现操作系统没有网络连接。我对 Linux 很陌生。
我注意到了一些 similar posts ，但是到目前为止我见过的唯一 “solution” 是拧紧无线连接并购买 USB-ethernet 适配器。如果我在家用这台电脑就好了。但这是在办公室里，而且只有 WiFi。
有什么办法可以让无线适配器正常工作吗？
Mac Book Pro，视网膜，13 英寸，2012 年末\nCPU 2.5 Ghz Intel Core i5\n内存 8GB

最佳思路
请执行以下操作：
sudo apt-get update
sudo apt-get install firmware-b43-installer
如果未连接，请重新启动并从脚本发布新文件。
没有互联网：
将 b43updated.zip 文件下载到 USB 闪存驱动器，然后将该文件拖放到 ubuntu 桌面。右键单击它并选择在此处提取。
打开终端并执行以下操作：
sudo mkdir /lib/firmware/b43
sudo cp Desktop/b43/* /lib/firmware/b43
sudo modprobe -rv b43
sudo modprobe -v b43
如果重新启动后没有出现。
次佳思路
我在 macMini 上也遇到了同样的问题
>lspci -nn
02:00.0 Network controller [0280]: Broadcom Corporation BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)
这对我有用：
sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source
sudo apt-get install linux-firmware-nonfree b43-fwcutter firmware-b43-installer
然后重新启动
