升级办法：

在升级之前，请把设备的配置信息都记录好，你可能在升级之后需要使用到这些信息。这些重要的信息包括登陆密码，安全设定，VPN 策略及 ISP 的配置信息等等。
首先从官方网站下载升级文件，一切准备就绪就可以开始升级。

1. 下载 Firmware到本地计算机，下载的Firmware需放到英文目录下，如d:/FVS318G，不要放在桌面或中文目录下。
2. 通过浏览器登陆到管理页面。
3. 在Administration > Settings Backup & Upgrade > Router Upgrade菜单中点击“浏览”按钮，选中下载的Fimware文件，并点击upload。在弹出的页面中点击“确定”FVS318G开始升级。
4. 升级完成后，FVS318G将显示系统已成功升级，并自动重新启动
5. 恢复出厂设置值，即在通电的情况下按着复位键约15秒即可。
