想知道在Linux中你正在使用的網(wǎng)卡是什么嗎？ 在Linux中很容易就找出網(wǎng)卡的生產(chǎn)商。打開一個終端并輸入下面的額命令：
sudo lshw -C network
如果上面的命令不能在sudo下使用，那就別用 sudo 的特權(quán)模式。它的輸出看上去有點奇怪但是很有用。
*-network

如你所見，我Macbook Air上的無線網(wǎng)卡是BCM4360，這是一款在Ubuntu下面很容易出現(xiàn)無法檢測無線網(wǎng)絡(luò)問題的網(wǎng)卡。
lshw 命令實際上是用來列出硬件的，因此命令的名字是lshw。帶上網(wǎng)絡(luò)的選項后，就會只過濾出網(wǎng)絡(luò)硬件了。

另外你還可以使用lspci命令來顯示PCI總線上的信息。你應該使用普通用戶來運行這個命令。只需要在命令行下輸入：
lspci
命令的輸出看上去想這樣：
00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Controller (rev 09)
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)

04:00.0 SATA controller: Marvell Technology Group Ltd. 88SS9183 PCIe SSD Controller (rev 14)
這些命令會同時列出有線和無線的網(wǎng)卡。你應該注意到上面的輸出中顯示我的系統(tǒng)中沒有有線網(wǎng)卡。因為我使用的是Macbook Air，它沒有以太網(wǎng)端口
