1，下載驅動

使用注意：

2.編譯安裝
$make
$sudo make install
3.關於hostapd的配置文件
# Basic configuration interface=wlan0 ssid=11111 channel=10 #bridge=br0 # WPA and WPA2 configuration macaddr_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 configuration driver=rtl871xdrv ieee80211n=1 hw_mode=g device_name=RTL8192CU manufacturer=Realtek ••••••••••
4.基本操作
sudo ifconfig wlan1 up //打開端口 sudo hostapd -B /etc/hostapd/hostapd.conf sudo hostapd -d /etc/hostapd/hostapd.conf sudo hostapd /etc/hostapd/hostapd.conf
5.手機搜索不到SSID（wifi熱點的名字）
在網上找到
手機收不到SSID 系統是archlinux，做軟ap。之前是運行一個ad-hoc的腳本，有些android手機不支持ad-hoc模式，就安裝了hostapd， 運行 # hostapd -d /etc/hostapd/hostapd.conf 手機可以連上＆上網 重啟電腦再運行hostapd，手機就不能獲取ip地址了。必須運行ad-hoc腳本，再運行hostapd才行。 是不是哪里沒有設置好？ 另外，手機連上ap后似乎不能建立安全鏈接，wifi信號是灰色的不是藍色，gtalk不能登錄，但能看到在線好友？？？？？
於是就編輯了一個ad-hoc的wifi熱點，熱點名稱與hostapd中配置的名稱一樣，這里為”11111“
顯示“11111”已連接上網絡，然后就可以收到SSID 的信號（信號由hostapd產生）。
6.手機收到信號后，連接不上，顯示身份信息驗證失敗
后來嘗試了很多辦法
你可以檢查： 1、你的AP或無線路由器和你終端的加密方式是否相同 2、密鑰有沒有設置對 3、密鑰是字符還是ASCII碼 4、無線網絡經常會有相同SSID的，你聯的無線網絡是不是要聯的。 hostapd基本配置 http://www.cnblogs.com/zhuwenger/archive/2011/03/11/1980294.html

還是不行，后來想想hostapd產生的SSID應該與ad-hoc產生的wifi熱點沒關系，只是需要啟動一下ad-hoc而已。
看了看手機收到的SSID，選定靜態配置（沒有用到DHCP），然后及可以並使用了。

IPV4設置方法：1.與其他計算機共享
需要IPV4完成這個連接（不選）
無線提示連接上， 產生穩定的SSID，連接不上，hostapd沒有反應。
需要IPV4完成這個連接（選）
手機能連接上網，容易斷線。
2.已禁用
無線提示連接不上，產生不了穩定的SSID。
