下载小米路由器R1CL开发版

通过手动上传更新，更改固件版本

将之前地址栏URL中的 /web/home#router 替换为（密码为admin）

/api/xqsystem/set_name_password?oldPwd=123456789&newPwd=admin

如果网页返回 {“code”:0} ，则说明修改成功。

将之前地址栏URL中的

 /web/home#router 替换为/api/xqnetwork/set_wifi_ap?ssid=xiaomi&encryption=NONE&enctype=NONE&channel=1%3B%2Fusr%2Fsbin%2Ftelnetd

如果网页返回 {“msg”:“未能连接到指定WiFi(Probe timeout)”,“code”:1616}，则说明修改成功

先通过telnet登录，账号：root 密码：admin

sed -i ":x;N;s/if \[.*\; then\n.*return 0\n.*fi/#tb/;b x" /etc/init.d/dropbear
/etc/init.d/dropbear start
nvram set ssh_en=1; nvram commit

执行完，就可以通过ssh登录路由器了

备份

cd /tmp
mkdir rom

dd if=/dev/mtd0 of=/tmp/rom/ALL.bin
dd if=/dev/mtd1 of=/tmp/rom/Bootloader.bin
dd if=/dev/mtd2 of=/tmp/rom/Config.bin
dd if=/dev/mtd3 of=/tmp/rom/Factory.bin
dd if=/dev/mtd4 of=/tmp/rom/OS1.bin
dd if=/dev/mtd5 of=/tmp/rom/rootfs.bin
dd if=/dev/mtd6 of=/tmp/rom/OS2.bin
dd if=/dev/mtd7 of=/tmp/rom/overlay.bin
dd if=/dev/mtd8 of=/tmp/rom/crash.bin
dd if=/dev/mtd9 of=/tmp/rom/reserved.bin
dd if=/dev/mtd10 of=/tmp/rom/Bdata.bin

使用winsicp将配置备份，避免内存不足刷出砖头

#删除路由器/tmp/rom的备份文件，否则空间不够。将openwrt-ramips-mt7628-miwifi-nano-squashfs-sysupgrade.bin文件传到/tmp

mv -f /tmp/rom/openwrt-ramips-mt7628-miwifi-nano-squashfs-sysupgrade.bin /tmp/

下载官方编译好得固件：

https://downloads.openwrt.org/snapshots/trunk/ramips/mt7628/openwrt-ramips-mt7628-miwifi-nano-squashfs-sysupgrade.bin

执行安装

mtd -r write /tmp/openwrt-ramips-mt7628-miwifi-nano-squashfs-sysupgrade.bin firmware

修改lan网卡

vi /etc/config/network

加载luci（路由器需要连上网络）

opkg update
opkg install luci
/etc/init.d/uhttpd enable
/etc/init.d/uhttpd start

安装iperf3

输入命令:opkg install iperf3
创建自启脚本：
#!/bin/sh /etc/rc.common
START=99                #这里是启动优先级
STOP=15                 #这里是停止优先级
start(){
iperf3 -s &
}
stop(){
killall iperf3
}
restart(){
killall iperf3
iperf3 -s &
}
enable(){
iperf3 -s &
}
disable(){
killall iperf3
}

使能脚本自启：

touch /etc/init.d/myshell
chmod 777 /etc/init.d/myshell
ln -s  /etc/init.d/myshell  /etc/rc.d/S99myshell
/etc/rc.d/S99myshell enable
