Test the two bug boards is so boring… No good news. After that I decide to test some new feature: client mode.
It is easy to setup OpenWrt to client mode. It connected to my home router VongerWifi.
We need to change two files.
One is /etc/config/wireless:
config wifi-device 'radio0' option type 'mac80211' option channel 'auto' option hwmode '11ng' option path '10180000.wmac' list ht_capab 'GF' list ht_capab 'SHORT-GI-20' list ht_capab 'SHORT-GI-40' list ht_capab 'RX-STBC1' option htmode 'HT20' config wifi-iface option device 'radio0' option network 'wwan' option mode 'sta' option ssid 'VongerWifi' option encryption 'psk2' option key 'passwordforwifi'
add two line after /etc/config/network to enable get ip address from your home router.
config interface wwan option proto 'dhcp'
restart network by this script.
/etc/init.d/network restart wifi up
Now the board shows this:
[ 555.840000] wlan0: deauthenticating from 0c:82:68:24:84:86 by local choice (reason=3) [ 556.740000] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 558.510000] wlan0: authenticate with 0c:82:68:24:84:86 [ 558.550000] wlan0: send auth to 0c:82:68:24:84:86 (try 1/3) [ 558.560000] wlan0: authenticated [ 558.580000] wlan0: associate with 0c:82:68:24:84:86 (try 1/3) [ 558.590000] wlan0: RX AssocResp from 0c:82:68:24:84:86 (capab=0x431 status=0 aid=4) [ 558.610000] wlan0: associated [ 558.610000] IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready
The client mode is working now.

I find I can not ping from my board to my computer, and my computer can not ping board. That is not firewall problem. I find that is route problem.
root@OpenWrt:/etc/config# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default OpenWrt.lan 0.0.0.0 UG 0 0 0 wlan0 192.168.1.0 * 255.255.255.0 U 0 0 0 br-lan 192.168.1.0 * 255.255.255.0 U 0 0 0 wlan0
There should be a default gateway to 192.168.1.1 which is my router.
route add 192.168.1.0 gw 192.168.1.1
After this, it still does not work.
use ifconfig, I find the problem, br-lan already take 192.168.1.1. Just turn off it.
ifconfig br-lan down
Now, my computer is able to ping the VoCore board and VoCore board is able to ping the computer. Everything works great.
