![Broadcom 无线驱动程序在 ubuntu 14.04 中不起作用。我的 pci id 是 [14e4:43b1] (rev 03)](https://linux22.com/image/1124470/Broadcom%20%E6%97%A0%E7%BA%BF%E9%A9%B1%E5%8A%A8%E7%A8%8B%E5%BA%8F%E5%9C%A8%20ubuntu%2014.04%20%E4%B8%AD%E4%B8%8D%E8%B5%B7%E4%BD%9C%E7%94%A8%E3%80%82%E6%88%91%E7%9A%84%20pci%20id%20%E6%98%AF%20%5B14e4%3A43b1%5D%20(rev%2003).png)
我在 Yoga 3 Pro 上双启动了 Win8 和 Ubuntu。我遇到了与其他用户相同的问题：
- 当我安装 Ubuntu 时，wifi 无法工作，除非我将其列入黑名单
ideapad_laptop。 - 触摸板/触摸屏将无法工作。
- 所以我更新到了最新的内核（3.19.0-031900-generic），触摸板和触摸屏都可以使用了，但我无论如何都无法让 wifi 工作。我尝试了找到的所有建议。
有什么想法吗？我很乐意提供任何您认为可能有助于缩小范围的信息。
以下是无线脚本的结果：
注意：脚本输出显示wl在/etc/modules但我手动添加了，当我运行时sudo modprobe wl，我得到了modprobe: FATAL: Module wl not found.。

答案1
在继续之前，让我们先确定它ideapad-laptop是否按预期工作。从终端：
sudo modprobe ideapad-laptop
现在您的无线开关和触摸板/触摸屏是否都正常工作？如果是，请删除您之前添加的黑名单。现在来看看无线：
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl
请注意并发布任何错误。
