0. uname -r
1. sudo lshw -numeric -class network
2. sudo ifconfig -a
3. sudo route -nv
4. sudo rfkill list all
上面命令在终端运行结果如下（我是用Vmware装的Ubuntu），请问是啥原因

虚拟机启动后不会将宿主机的无线网卡认作“无线网卡”，而会认作“有线网卡"。不管你有几块网卡，象vmware workstation这样的虚拟机软件里，任何一个时刻一般应该只能看到一块网卡：如果你的宿主机用的是有线网卡，那么在虚拟机里看到的就应该是以这块有线网卡为虚拟网络设备的一块“有线网卡”；如果你的宿主机正在使用的是无线网卡，那么在虚拟机里看到的，就应该是以这块无线网卡为虚拟网络设备的一块“有线网卡”--对了，也是“有线”的，这个“有线”是虚拟机软件“虚拟”出来的一个网络设备，除了在底层用到了你那块无线网卡，在其他逻辑层面和“无线”毫无关系。。。

以下是我在virtualbox上使用宿主机上的无线网卡的例子：

注意：上面虚拟机设置里我选择是虚拟机使用宿主机的无线网卡，但是虚拟机启动完成后这块无线网卡被虚拟机软件虚拟成了一块“有线网卡”--“82540EM Gigabit Ethernet Controller” ！

1-1. VMXNET: The VMXNET virtual network adapter has no physical counterpart. VMXNET is optimized for performance in a virtual machine. Because operating system vendors do not provide built-in drivers for this card, you must install VMware Tools to have a driver for the VMXNET network adapter available.
1-2. VMXNET 2 (Enhanced) 請詳閱上文
1-3. VMXNET 3 請詳閱上文

2. 請提供 VMware 版本
