Arduino Yun 網路

Arduino Yun 也可同時啟動 AP+STA 模式，但測試時花了很多時間
因為 Arduino Yun 真的比 Linkit 7688 慢很多

回復AP模式或出廠值
1. 使用 WLAN 按鈕
按5秒，wifi 回AP模式 SSID=Arduino-Yun-XXXXXXXXXXXX, IP=192.168.240.1
按30秒，linux 環境回復出廠值，清除板上的 Flash 記憶體
2. 登入作業系統，使用命令
wifi-reset-and-reboot
reset-to-factory-anyway

wifi-reset-and-reboot 中加入下一行，才能正確回復AP模式

$UCI "delete" "wireless.@wifi-iface[1]"

設定檔位於 /etc/config

dhcp, network, wireless, firewall

使用網頁 (Arduino Luci)設定，新增 Wi-Fi Station 網路

Network/Wifi/Scan
Join Network
取消勾選 An additional network will be created if you leave this unchecked.

沒有取消勾選，會導致 AP 網路被取消掉

uci set wireless.@wifi-iface[1].ssid='DigiChance'

uci set wireless.@wifi-iface[1].key='xxxxx'

uci set wireless.@wifi-iface[1].encryption='psk2'

uci set wireless.@wifi-iface[1].bssid='B8:55:10:56:05:20'

uci commit wireless

uci set network.wwan.proto='static'

uci set network.wwan.ipaddr='192.168.1.60'

uci set network.wwan.netmask='255.255.255.0'

uci set network.wwan.gateway='192.168.1.1'

uci set network.wwan.dns='192.168.1.1'

uci commit network

修改完執行

/etc/init.d/network restart

相關命令
wifi up
wifi down
wifi status
ifconfig
ifconfig eth1 up
ifconfig eth1 down
ifconfig eth1 192.168.1.61 netmask 255.255.255.0

ifup EWAN // 參考 /etc/config/network

ifdown EWAN // 參考 /etc/config/network

同時啟動 ap+sta 模式，網路不用密碼，使用 MAC filter，會出問題，一直找不到如何解決

1. 不用密碼命令

uci set wireless.@wifi-iface[1].encryption='none'

2. MAC filter 似乎會檢查 BSSID

uci set wireless.@wifi-iface[1].bssid='B8:55:10:56:05:20'

3. 切開不同的網段，似乎能解決問題，但不同網段

uci set network.wwan.ipaddr='192.168.3.60'

若開機時沒接上有線網路，會導致無線網路開不起來
停止網路
uci set network.EWAN.auto='0'

開機後(無線網路啟動後)再啟動有線網路

編輯 /etc/rc.local

加入

ifconfig eth1 192.168.1.61 netmask 255.255.255.0

或

ifup wan

ifup EWAN
