获取Broadcom Wifi卡上class

Wifi无法正常工作，我无法在网络设置中创建新的（wifi）连接。

正如在这个答案中提到的，我应该问一个新的问题，如果我的PCI ID没有列出，而且很遗憾我有一个：14e4：43ae。 我正在运行最新版本的Ubuntu。 uname -r返回4.2.0-18-generic 。

sudo lspci -vnn

sudo lshw | grep wireless的输出 sudo lshw | grep wireless是空的。

编辑：我现在真的被这个Broadcom芯片烦恼了！ 无论如何，我订购了一个英特尔Wifi芯片，我将用它取代我的电流。
