OpenWrt：WRTnode2P实现联网

登陆WRTnode2P（telnet或ssh）

使用microUSB供电，一头接在WRTnode2P标准底板的迷你usb接口，一头接到一个超过500ma的5v供电的地方，上电以后，WRTnode2P底板上的蓝灯亮起，里面的OpenWrt开始启动了，20秒后就能发现一个WRTnode2P_xxxx（xxxx指WRTnode2P mac地址的后四位）的Wi-Fi，用电脑或手机或ipad连上，密码是12345678。

首先通过ping openwrt.lan看看连上WRTnode2P没有，WRTnode2P的IP地址是192.168.8.1，openwrt.lan这个域名会被WRTnode2P拦截并解析到自己的ip地址。

如果第一次登陆WRTnode2P，或者之前没有给OpenWrt的root用户设置密码，那就telnet：

$ telnet 192.168.8.1 

或是

$ telnet openwrt.lan

或者已经设置过root密码了，那就ssh:

$ ssh root@192.168.8.1

或是

$ ssh [e-mail]

联网

aps是WRTnode的自定义命令，扫描当前的Wi-Fi，结果如下所示：

# aps

然后将WRTnode2P连上路由器：

# setwifi 连接的路由器SSID 对应的密码

看看WRTnode2P有没有从上级路由DHCP获取IP地址:

root@OpenWrt:/# ia
apcli0    Link encap:Ethernet  HWaddr 66:51:7E:00:82:8C  
          inet addr:192.168.0.102  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::6451:7eff:fe00:828c/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:83 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:31804 (31.0 KiB)  TX bytes:6514 (6.3 KiB)

获取到IP后，看看是不是已经连上互联网了：

root@OpenWrt:/# ping www.baidu.com
