Ⅰ TP-LINK WR703N刷OPENWRT 有线接口eth0一直为离线状态
你直接由原带固件升级的话，要选对固件类型，选带factory字样的
比如：openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin
Ⅱ 极贰openwrt 编译 7620a+7621e，能够开启 2.4G，5G 该怎么打开
操作步骤如下：
1.下载openwrt最新代码
2. 下载openwrt官方的7621e驱动
3. 参考 打上hc5761的补丁，使用其hc5761的config，并开启mtk-wifi-gpl
4. 编译完成通过ttl，sysupgrade -F -n
openwrt-ramips-mt7620a-hiwifi-hc5761-squashfs-sysupgrade.bin刷机
5. 完成重启，2.4G能够开启

Ⅲ openWRT如何修改MAC地址
1、修改 eth0 mac地址：
编辑 /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。
这就最纠结了直接修改 /etc/config/wireless中的mac是没用的，并且修改后无线网络会无法启动。
在研究了/sbin/wifi脚本后，只能通过迂回战术来进行解决。
编辑 /sbin/wifi；修改如下一段，增加内容。
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 重启，就能看到所有修改都生效了。
