Forgot the WiFi password: connect via Ethernet cable, open a browser to your router's admin address (commonly 192.168.1.1 or 192.168.0.1), and check the wireless settings page. Forgot the admin password: you'll need a factory reset (hold the pinhole RESET button ~10 seconds), then reconfigure your PPPoE login and WiFi name/password from scratch. Take a screenshot of your ISP login details beforehand if you can.

忘记WiFi密码：用网线连接路由器，浏览器打开路由器管理地址(常见是192.168.1.1或192.168.0.1)，在无线设置页面查看。忘记后台管理密码：需要恢复出厂设置(按住针孔RESET键约10秒)，然后重新配置PPPoE账号和WiFi名称密码。建议提前截图保存好ISP的登录信息。
