Edison Ubilinux Access Point

关于在Edison Ubilinux中开启AP模式的问题，其实实际上真的很简单，但是因为我没有用谷歌查询，所以查找到的资料几乎都是不能解决问题的，然后人家有谷歌的就一下子解决出来了，我也是醉了。为了这个不用谷歌的血的教训，我决定写下这篇博客，希望对以后的人有帮助。

如果你用的就是Edison Ubilinux，照下列步骤应该就可以了，我用的是hostapd2.3版本。

第一步：

# vim /etc/network/interfaces

如果本来有设置自动连接WiFi的，先将

auto wlan0

iface wlan0 inet dhcp

wpa_ssid:......

wpa_.......注释掉；

再将以下四句去掉注释（其实这里不是就写着以下四行是提供给hostapd用的吗？）

# And the following 4 lines are for when using hostapd...
auto wlan0
iface wlan0 inet static

address 192.168.42.1

netmask 255.255.255.0

第二步：

#vim /etc/hostapd/hostapd.conf

driver=nl80211

ssid=（自己定义一个名字）

wpa_passphrase=(设置一个密码)

其他按照默认就行，不用想其他教程那样改那么多

第三步：

#vim /etc/default/hostapd

将下面这行去掉注释，并加上hostapd.conf 的路径，如下：

DAEMON_CONF="/etc/hostapd/hostapd.conf"

第四步：

# /etc/init.d/hostapd restart

#hostapd -dd /etc/hostapd/hostapd.conf (-dd是显示详细信息，-B是后台执行，-v是查看hostapd的版本，不加是直接执行，各种选项请查看hostapd --help)

以下是在我的Edison上开启hostapd的详细信息：
