我是 Linux 新用户，我在笔记本电脑上安装了 xubuntu 15.04，但 wifi 无法使用（这似乎是一个常见问题）。我在办公室电脑的虚拟机中运行相同的发行版，它在那里运行良好。如果我将笔记本电脑启动到 Windows，wifi 也可以使用。我几乎尝试了我读到的所有方法，但都不起作用。
具体来说，我在网络下拉菜单中看不到“启用无线”。
注意：sudo rfkill list all我的终端中没有输出任何内容，这使得很难遵循以此开头的任何提示。
‘lspci’ 输出在这里：

答案2
是的。这是因为您的虚拟机中的操作系统没有自己的硬件，而网卡为您提供了一些选项。在您的虚拟机设置中为您的操作系统选择桥接网络并重新启动您的虚拟操作系统。然后检查您的浏览器。
它没有显示无线连接，但作为以太网内部连接。
