#Deco P9 trouble
Since some weeks, the main access point is emitting a whistling noise.
Is it a bad news or not ? What can I do to eliminate this sound ?

Hi, here are some suggestions for your reference:
- Please move the Deco away from the high-power home appliances.
- Reset the Deco by holding the reset pinhole for 1s.
If it was still the same, please reach out to local technical support for further assistance:
