openwrt之wifi 脚本指令与 uci 指令/ ap + sta / 配置连接上级路由器

root@xxx:~# wifi help
Usage: /sbin/wifi [down|detect|reload|status]

enables (default), disables or detects a wifi configuration

root@xxx:~# wifi up/down  //打开、关闭wifi 接口（包括ap、sta），但是不写会存储（重启设备，恢复默认值）

root@xxx:~# wifi detects > /etc/config/wireless   // 生成无线配置文件（uci get / set 获取/设置此配置文件内的值）

root@xxx:~# wifi status

root@xxxx:~# uci get wireless.@wifi-iface[1].ifname   //获取 wifi interface 1 的名称

wlan0-1

root@Leedarson:~# uci set wireless.@wifi-iface[1].disabled=0    //设置 打开wifi interface 1

每次设置参数后都需要提交回写uci commit 更改/etc/config/wireless配置文件内容，然后执行/etc/init.d/network restart 后方能生效。

总结 ：　

    wifi up 会启动wifi内的所有接口（ap、sta)，  uci set wireless.@wifi-iface[1].disabled=0 能打开某个接口，ap 或者sta ，需要执行uci commit 回写，而后执行wifi up生效,并不会重启网卡！

    连接上级路由器配置：  

        root@xx:~# uci set wireless.@wifi-iface[1].ssid=TP-LINK_EE520F                 //wifi 名称
        root@xx:~# uci set wireless.@wifi-iface[1].bssid=8A:25:93:F2:52:0F             //wifi mac 地址
        root@xx:~# uci set wireless.@wifi-iface[1].key=abcd@1234                         //wifi 密码

        root@xx:~# uci commit                                                                                  

        root@xx:~# wifi up
