轉載部分：

本人筆記本的型號為lenovo G510，Ubuntu 中，通常有線網絡卡為eth0，無線網絡卡則為wlan0，後續增加的以此類推（可能某些無線網絡卡型號命名為eth1，而非wlan0。用ifconfig命令檢視系統的網絡卡資訊，根本沒有出現wlan0或者eth1，說明驅動沒有安裝。

安裝網絡卡驅動的話，需要了解網絡卡型別，用lspci命令檢視，發現我的網絡卡是

Broadcom Corporation BCM43142 802.11b/g/n (rev 01)

這個網絡卡是一個很老的網絡卡，已經很少用了，所以驅動非常難下載。嘗試了很多辦法，終於在下面的網上找到了：

我所做的事情如下：

sudo apt-get install linux-headers$(uname -r | grep -Po "\-[a-z].*")

sudo apt-get install build-essential dkms

sudo apt-get install dpkg

sudo apt-get install bcmwl-kernel-source

然後無線網路就可以用了，用ifconfig命令發現出現了eth1
