Linux下网卡BCM4313的安装

我遇到的问题：打开网络管理->wifi 显示固件缺失 
通过：

1	lspci | grep Wireless

显示：

1	08:00.0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01)

得知网卡为BCM4313

官方文档解释如何安装BCM4313驱动

https://wiki.debian.org/brcm80211

Installation

1. Add a "non-free" component to /etc/apt/sources.list, for example:

   # Debian 8 "Jessie"deb http://httpredir.debian.org/debian/ jessie main contrib non-free

2. Update the list of available packages and install the firmware-brcm80211 package:

   # apt-get update && apt-get install firmware-brcm80211

3. As the driver may already be loaded, reinsert the module to access installed firmware:

   # modprobe -r brcmsmac ; modprobe brcmsmac

4. Configure your wireless interface as appropriate.

以上的操作为在Debian 8的操作系统上
