在Ubuntu系统上搜寻并显示网卡信息的方法
Abhishek
想知道在Linux中你正在使用的网卡是什么吗？ 在Linux中很容易就找出网卡的生产商。打开一个终端并输入下面的额命令：
sudo lshw -C network
如果上面的命令不能在sudo下使用，那就别用 sudo 的特权模式。它的输出看上去有点奇怪但是很有用。
*-network

如你所见，我Macbook Air上的无线网卡是BCM4360，这是一款在Ubuntu下面很容易出现无法检测无线网络问题的网卡。
lshw 命令实际上是用来列出硬件的，因此命令的名字是lshw。带上网络的选项后，就会只过滤出网络硬件了。

另外你还可以使用lspci命令来显示PCI总线上的信息。你应该使用普通用户来运行这个命令。只需要在命令行下输入：
lspci
命令的输出看上去想这样：

这些命令会同时列出有线和无线的网卡。你应该注意到上面的输出中显示我的系统中没有有线网卡。因为我使用的是Macbook Air，它没有以太网端口
