Debian/Linux 下无线网卡驱动的安装

我的 PC 型号是 Acer V3-572G, 安装了 Debian 后, 发现只能通过有线网络上网, 无法识别无线网卡, 以下是解决的过程(不局限于此型号 PC):

• 在命令行键入 lspci , 得到网卡型号「BCM43228」

  xox@debian-x64:~$ lspci

• 使用搜索引擎得到特定型号的固件包
  如下图, 第一个搜索结果中即有相关信息 wl - Debian Wiki
  

• apt-get install 安装驱动

  # apt-get update
  # apt-get install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms
  

• 重启即可使用无线网络
