近日收到两台路由，可以插minipcie（USB）接口的网卡，在openwrt上折腾了下，感觉很不方便，于是就利用周末，在padavan上折腾了。第一次玩这个系统，不熟悉，都是自己摸索的。
工具：
路由一台（配置7620A+7610E,16+128）
4G网卡两个，龙尚U8300C和EC20
串口小板，编程器，ubuntu服务器等
具体编译过程就不说了，直接参照wiki就可以了，注意的是代码默认是N56N，我这个硬件与AC51U比较一致，直接用AC51U编译了。

添加4G网卡进来，这个与openwrt和Android一样的：

其他坑：主板带了个硬件看门狗，刷非他们的系统会不断重启，拆了看门狗芯片，把供电线直接短接！
