小米路由R3G 安装OpenWrt 全记录

刷机 开发版

刷机 OpenWrt

不支持SFTP

OpenWrt 默认不支持 SFTP，请使用WINSCP的SCP模式传输文件！
OpenWrt 默认不支持 SFTP，请使用WINSCP的SCP模式传输文件！
OpenWrt 默认不支持 SFTP，请使用WINSCP的SCP模式传输文件！

breed 这个 bootloader 可以不用安装
如果后续 更换为其他固件, 建议安装 breed
否则 在OpenWrt更换其他固件 还是有点麻烦.

备份系统

可选操作， 可以跳过

可以保存在U盘中，
也可以保存在/tmp目录下, 使用WINSCP的SCP模式传输出来

无响应/忘记密码 重置

情况1:

当错误的配置了 OpenWrt 导致无法启动时, 如过跨大版本升级, 密码
当OpenWrt配置了错误的 IP 无法登录时
  1. 按住 reset 按键 直到 红灯闪烁, 等待 重启.
  2. 进入 192.168.1.1 web页即可.

情况2:

如果设置了错误的配置, 导致OS没有完整启动,用上面的办法没有时.

  1. 断电->上电

  2. 用ping工具一直ping 192.168.1.1

  3. 屏幕上会有短暂的瞬间 能够ping通

  4. 用牙签 顶一下 R3G 的reset 按钮,立即松开

  5. 用SSH 工具连接进去 ssh root@192.168.1.1

  6. 进入故障模式, 输入 恢复为出厂设置
