Ⅰ TP-LINK WR703N刷OPENWRT 有線介面eth0一直為離線狀態

你直接由原帶固件升級的話，要選對固件類型，選帶factory字樣的
比如：openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin

Ⅱ 極貳openwrt 編譯 7620a+7621e，能夠開啟 2.4G，5G 該怎麼打開

操作步驟如下：
1.下載openwrt最新代碼
2. 下載openwrt官方的7621e驅動
3. 參考 打上hc5761的補丁，使用其hc5761的config，並開啟mtk-wifi-gpl
4. 編譯完成通過ttl，sysupgrade -F -n
openwrt-ramips-mt7620a-hiwifi-hc5761-squashfs-sysupgrade.bin刷機

5. 完成重啟，2.4G能夠開啟

Ⅲ openWRT如何修改MAC地址

1、修改 eth0 mac地址：
編輯 /etc/rc.local，ifconfig eth0 down;ifconfig eth0 hw ether d8:64:c7:5e:f1:c6;ifconfig eth0 up。
2、修改wireless mac地址。
這就最糾結了直接修改 /etc/config/wireless中的mac是沒用的，並且修改後無線網路會無法啟動。
在研究了/sbin/wifi腳本後，只能通過迂迴戰術來進行解決。
編輯 /sbin/wifi；修改如下一段，增加內容。
set_wifi_up() {
echo wifi_up;ls /tmp/run/*.conf

kill `cat /var/run/wifi-phy0.pid`
sed -i s/^bssid=.*/bssid=d8:64:c7:5f:f1:c6/ /var/run/hostapd-phy0.conf
hostapd -P /var/run/wifi-phy0.pid -B /var/run/hostapd-phy0.conf

local cfg="$1"
echo wifi_up 2;ls /tmp/run/*.conf
local ifname="$2"
echo wifi_up 3;ls /tmp/run/*.conf
uci_set_state wireless "$cfg" up 1
uci_set_state wireless "$cfg" ifname "$ifname"

}

3、修改完成 。
sync;reboot 重啟，就能看到所有修改都生效了。
