1，下载驱动
https://github.com/lwfinger/rtl8188eu
使用注意：

2.编译安装
$make
$sudo make install
3.关于hostapd的配置文件
# Basic configurationinterface=wlan0
ssid=11111
channel=10
#bridge=br0# WPA and WPA2 configurationmacaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=3
wpa_passphrase=123456789
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP# Hardware configurationdriver=rtl871xdrv
ieee80211n=1
hw_mode=g
device_name=RTL8192CU
manufacturer=Realtek
••••••••••4.基本操作
sudo ifconfig wlan1 up //打开端口 sudo hostapd -B /etc/hostapd/hostapd.conf sudo hostapd -d /etc/hostapd/hostapd.conf sudo hostapd /etc/hostapd/hostapd.conf
5.手机搜索不到SSID（wifi热点的名字）
在网上找到
手机收不到SSID 系统是archlinux，做软ap。之前是运行一个ad-hoc的脚本，有些android手机不支持ad-hoc模式，就安装了hostapd， 运行 # hostapd -d /etc/hostapd/hostapd.conf 手机可以连上＆上网 重启电脑再运行hostapd，手机就不能获取ip地址了。必须运行ad-hoc脚本，再运行hostapd才行。 是不是哪里没有设置好？ 另外，手机连上ap后似乎不能建立安全链接，wifi信号是灰色的不是蓝色，gtalk不能登录，但能看到在线好友？？？？？
于是就编辑了一个ad-hoc的wifi热点，热点名称与hostapd中配置的名称一样，这里为”11111“
显示“11111”已连接上网络，然后就可以收到SSID 的信号（信号由hostapd产生）。
6.手机收到信号后，连接不上，显示身份信息验证失败
后来尝试了很多办法
你可以检查： 1、你的AP或无线路由器和你终端的加密方式是否相同 2、密钥有没有设置对 3、密钥是字符还是ASCII码 4、无线网络经常会有相同SSID的，你联的无线网络是不是要联的。 hostapd基本配置 http://www.cnblogs.com/zhuwenger/archive/2011/03/11/1980294.html

还是不行，后来想想hostapd产生的SSID应该与ad-hoc产生的wifi热点没关系，只是需要启动一下ad-hoc而已。
看了看手机收到的SSID，选定静态配置（没有用到DHCP），然后及可以并使用了。

IPV4设置方法：1.与其他计算机共享
需要IPV4完成这个连接（不选）
无线提示连接上， 产生稳定的SSID，连接不上，hostapd没有反应。
需要IPV4完成这个连接（选）
手机能连接上网，容易断线。
2.已禁用
无线提示连接不上，产生不了稳定的SSID。
