我知道这听起来很相似，但我的问题很独特。我有一台新的 HP Pavilion 15-p073TX NB PC。最近我安装了 Ubuntu 14.04.2，但无法启动 WIFI。我搜索了一下，得到了一些答案这里和这里。但到现在为止似乎什么都没有起作用。
lspci -vvnn | grep -A 9 Network给了我以下内容：

答案1
您需要从下载http://packages.ubuntu.com/utopic/amd64/bcmwl-kernel-source/download并安装，你现在的版本没有与 3.16 内核兼容所需的补丁
答案2
在安装 ubuntu 14 后，我们遇到了 Acer Aspire e5 新笔记本电脑中 wifi 无法使用的问题。我们还尝试使用以下命令安装驱动程序。
sudo apt-get 安装 bcmwl-kernel-source
但是我们得到了无法找到包的错误。后来通过输入命令找到了解决方案
sudo apt-get 更新
这样就更新了所有软件包。此后，bcmwl-kernal-source 的安装开始进行。
安装后，wifi 开始工作了！！感谢上述帖子。
问候，Gopinath
