Applies to

  3. Make sure you choose the new Wi-Fi source you want to connect to.
  4. After successfully pairing the purifier, connect it for at least 15 minutes
  5. Check if the firmware is updated. Information can be found in the Wellbeing application in the "Product information" section. Firmware after version 2.20 works with all routers.

Alternatively, change your home router's security protocol from WEP / WPA to WPA2 and restart the attachment. For detailed instructions, check the router documentation
