No internet no happiness

Now we will connect WRTnode2R to the internet. of course, you must have a 2.4G Wi-Fi ap or router with has connected on the internet.

root@OpenWrt:~# aps

'aps' is the command of WRTnode2R to scan the Wi-Fi available, the output of 'aps' looks like this:

WRTnode AP scaner.
Begin scaning APs, pls wait...
APs available are...

ok,we will connect one:

root@OpenWrt:~# setwifi SSID_you_connetctin the_password

be careful, there's a space between the SSID and the password
Such as:

root@OpenWrt:~# setwifi TP_linkAB33CD my_password

Press Enter and wait 5 seconds, or sometimes we need to reconnect our computer to the WRTnode2R's SSID, so let's see if we have got the IP address from uppter router:

root@OpenWrt:~# ia

we'll see

root@OpenWrt:~# ia
apcli0    Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
          inet addr:  Bcast:  Mask:
          inet6 addr: xxxx::xxxx:xxxx:xxxx:xxxx/xx Scope:Link
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

sometimes getting the IP address will lasts more than 5 seconds, so be patient. Once we got the IP address, let's see if the board have access the internet:

root@OpenWrt:~# ping
PING ( 56 data bytes
64 bytes from seq=0 ttl=54 time=6.071 ms

See, thus we connected our computer to the WRTnode2R, and we connected the WRTnode2R to the internet.
