近日收到兩臺(tái)路由，可以插minipcie（USB）接口的網(wǎng)卡假抄，在openwrt上折騰了下怎栽，感覺很不方便，于是就利用周末宿饱，在padavan上折騰了齿兔。第一次玩這個(gè)系統(tǒng)，不熟悉感帅，都是自己摸索的圆雁。
工具：
路由一臺(tái)（配置7620A+7610E,16+128）
4G網(wǎng)卡兩個(gè)，龍尚U8300C和EC20
串口小板为黎，編程器邮丰，ubuntu服務(wù)器等
具體編譯過程就不說了行您，直接參照wiki就可以了，注意的是代碼默認(rèn)是N56N剪廉，我這個(gè)硬件與AC51U比較一致娃循，直接用AC51U編譯了。

添加4G網(wǎng)卡進(jìn)來斗蒋，這個(gè)與openwrt和Android一樣的：
