1、查看你的网卡是否支持AP模式。现在网卡一般都支持

k@k-C410:~$ iwlist
Usage: iwlist [interface] scanning [essid NNN] [last]
              [interface] frequency
              [interface] channel
              [interface] bitrate
              [interface] rate
              [interface] encryption
              [interface] keys
              [interface] power
              [interface] txpower
              [interface] retry
              [interface] ap
              [interface] accesspoints
              [interface] peers
              [interface] event
              [interface] auth
              [interface] wpakeys
              [interface] genie
              [interface] modulation

如果显示 ap，则表示你的网卡支持 ap 模式。

也可以用下面命令查看：

k@k-C410:/etc$ iw list

你也可以到下面地址查看你的网卡是否支持ap

2、建立无线 ap

hostapd：

主页：http://w1.fi/hostapd/

文档：http://wireless.kernel.org/en/users/Documentation/hostapd?highlight=%28hostapd%29

ubuntu下可以用下面命令安装：

sudo apt-get install hostapd

你也可以从源码编译。

k@k-C410:/home/hostap/hostapd$ sudo ./hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
nl80211: Could not configure driver mode
nl80211 driver initialization failed.
hostapd_free_hapd_data: Interface wlan0 wasn't started
