Linux xxx 3.2.0-4-686-pae #1 SMP Debian 3.2.65-1+deb7u1 i686 GNU/Linux 前情提要： 我家的minipc安装debian的经过记录 安装完毕后一直用的是有线拨号，wifi一直没用过，今天心血来潮配置下无线。 查找网上很多教程都是有关wpe的，安装测试都不得法导致用不起来，想其以前写过的文档debian7安装和配置小经验，去https://wiki.debian.org/WiFi 找答案。 首先找到
因为我这个是pci模式的网卡，所以点击pci，如果是其他模式请点其他模式。出来一堆型号，看看我的是什么型号吧。

搜索4325有2条，，一个是brcm80211，一个是wl，分别拉下来找到
Installation Debian 7 “Wheezy”
然后brcm80211
Add a “non-free” component to /etc/apt/sources.list, for example:
Debian 7 “Wheezy”
deb wheezy main contrib non-free Update the list of available packages and install the firmware-brcm80211 package:
apt-get update && apt-get install firmware-brcm80211
As the driver may already be loaded, reinsert the module to access installed firmware:
modprobe -r brcmsmac ; modprobe brcmsmac
Configure your wireless interface as appropriate.
再是wl
Add a “non-free” component to /etc/apt/sources.list, for example:
Debian 7 “Wheezy”
deb wheezy main contrib non-free Update the list of available packages. Install the relevant linux-headers and broadcom-sta-dkms packages:
apt-get updateapt-get install linux-headers-$(uname -r|sed ‘s,[^-]-[^-]-,,’) broadcom-sta-dkms
This will also install the recommended wireless-tools package. DKMS will build the wl module for your system. Unload conflicting modules:
modprobe -r b44 b43 b43legacy ssb brcmsmac
Load the wl module:
modprobe wl
Configure your wireless interface as appropriate. See also known issues.
https://wiki.debian.org/wl https://wiki.debian.org/brcm80211
全部设置完毕但是网卡还是不能启用，点击https://wiki.debian.org/WiFi/HowToUse 到Command Line一节
Find your wireless interface and bring it up:
ip aiwconfigip link set wlan0 up
Scan for available networks and get network details: $ su
iwlist scan
然后来到WPA-PSK and WPA2-PSK一段
$ wpa_passphrase 无线网卡ssid 无线网卡密码 network={ ssid=”myssid” #psk=”my_very_secret_passphrase” psk=ccb290fd4fe6b22935cbae31449e050edd02ad44627b16ce0151668f5f53c01b }
这段先保存下来，有用的 nano /etc/network/interfaces
auto wlan0 iface wlan0 inet dhcp wpa-ssid 你的ssid wpa-psk ccb290fd4fe6b22935cbae31449e050edd02ad44627b16ce0151668f5f53c01b (这个就是前面记录下来的文字中的一部分，和wpa-psk是一行的)
然后
ifup wlan0
debian的wiki做的很好，前面我花的时间都是瞎测试，一看wiki就会
