ERR W - 戴森 空气净化器

中文

含义

空气净化器的WiFi模块无法连接到家庭网络或通讯异常。本地净化功能不受影响，但远程控制、语音助手集成和App监控功能不可用。

常见原因

1. 净化器与无线路由器距离过远或隔墙信号衰减严重
2. 家庭宽带路由器重启或WiFi密码变更后未同步更新
3. 路由器开启了WPA3加密或仅5GHz频段，净化器不支持
4. 净化器WiFi模块固件过旧，与新款路由器不兼容
5. 局域网内有多个设备IP冲突

自助排查

1. 将净化器移近路由器后测试WiFi连接
2. 重启净化器（拔掉电源等待10秒后重新插入）
3. 在手机App中删除设备后重新添加，输入当前WiFi密码
4. 确认路由器开启2.4GHz频段，并关闭MAC地址过滤
5. 如反复尝试失败，可尝试使用以太网转接器（如有）或更新路由器固件

English

Meaning

The air purifier’s WiFi module cannot connect to the home network or has a communication error. Local purification is unaffected, but remote control, voice assistant integration, and app monitoring are unavailable.

Common Causes

1. Purifier too far from the wireless router, or signal attenuated by walls
2. Home broadband router restarted or WiFi password changed without updating the purifier
3. Router configured with WPA3 encryption or 5 GHz-only mode that the purifier does not support
4. Purifier WiFi firmware too old to be compatible with newer router models
5. IP address conflict with another device on the local network

Self-Check Steps

1. Move the purifier closer to the router and test WiFi connectivity
2. Reboot the purifier by unplugging it for 10 seconds, then plugging it back in
3. Delete the device from the app and re-add it using the current WiFi password
4. Confirm the router broadcasts on 2.4 GHz and has MAC address filtering disabled
5. If repeated attempts fail, try using an Ethernet adapter (if available) or update the router firmware
