很多人/很多地方都在谈论如何让这张卡发挥作用。但对我来说，这些方法都不管用。
其中大部分都是从 repo 中获取一些 broadcom 的东西，然后你的驱动程序将出现在附加驱动程序页面中。
sudo apt-get install bcmwl-kernel-source
sudo modprobe wl
可悲的是，这是我记得尝试过的唯一一种方法（抱歉，进出医院，吃了很多止痛药。现在我很难了解细节）但所有的办法都没有结果。
Ubuntu 17.10 64 位 budgie 环境。
在此先感谢所有能帮助我的人，让我不需要这条 200 英尺长的电缆，只需上网即可。
好吧，首先更新一下我的问题...我花了一些时间做了进一步的研究，PCI ID 14e4:42a0 和 BCM4360 适用于我的卡，并揭示了大量的信息，最值得注意的是，我一直在查看安装 Broadcom 无线驱动程序 系统无法读取该卡。不过 Windows 可以正常读取，所以我知道它确实可以正常工作。

答案1
在 BIOS 中禁用安全启动，然后重新安装所有内容。突然间，一切开始正常工作。
sudo apt-get purge bcwml-kernel-source
快速重启...
sudo apt-get install bcmwl-kernel-source
再次重新启动。
每次启动时，我首先检查的是托盘上的网络状态。这次，登录后，它已经为我显示了无线选项。通过其他驱动程序、lspci、iwconfig 等进行了检查。现在一切都显示该卡存在（并且正常运行）
安全启动似乎阻止了它的运行。
我对这个话题了解不够，所以无法再说什么……比如为什么。也许评论可以解释一下，可惜我不能。
答案2
在我的 Clevo N240WU 笔记本电脑上，我遇到了与您相同的症状（Wi-Fi 卡在 Linux 中无法识别，并且未显示在 lspci 输出中）。我尝试了不同的内核（4.10、4.13；全部相同）。
这种情况只发生在我使用旧版 BIOS 时。使用 UEFI 时，Wi-Fi 卡可以正常工作。
