使用的是这个帖子配置的。。
http://cubietech.com/forum.php?mod=viewthread&tid=2251


加载模块
$modprobe bcmdhd

添加"bcmdhd" 到 /etc/modules
$vi /etc/modules

下载安装
$apt-get install wifi-radar或者$apt-get install linux-firmware
重启$reboot

打开wifi
$ifconfig wlan0 up  
查找（看）wifi
$iwlist wlan0 scan   

$vi /etc/network/interfaces加入以下内容
auto wlan0
iface wlan0 inet dhcp
pre-up ip link set wlan0 up
pre-up iwconfig wlan0 essid your-ssid-here
wpa-ssid your-ssid-here
wpa-psk your-passwd-here

最后重启网络/etc/init.d/networking restart


注：老提示CFG80211-ERROR) wl_escan_handler : Couldn't find P2PIE in probe response/beacon  这个错误的话，执行以下命令
$ifconfig wlan0 down
$ifconfig wlan0 up
$etc/init.d/networking restart


我的配置文件如下

1. auto lo eth0
   
2. iface lo inet loopback
   
3. iface eth0 inet dhcp
   
4. auto wlan0
   
5. iface wlan0 inet dhcp
   
6. pre-up ip link set wlan0 up
   
7. pre-up iwconfig wlan0 essid 111111
   
8. wpa-ssid 111111
   
9. wpa-psk  111111111
   

复制代码

目前折腾出一个可行的方法
开机重启network
然后rfkill unblock all
再打开wlan0
再重启下network
就可以获取到ip地址了。

第十五行的关闭后自动又打开。。。
要修改那个文件？？

原来这样啊。。。我就是遇到这个问题好久了。。后来不知道怎么 解决的。。
现在又出现了。。
看这个帖子，是应该

rfkill卸了，再装就可以了，但是每次开机要手动再执行一边，我就换老版本了，换1.01没事?

就是说把rfkill卸载了？
再安装rfkill?

但是不会用命令卸载。。。
