@todi Could you describe your configuration, including your ISP modem?

@Sandbox What is the color of the deco led when the problem arises? Does the Deco publish its "final" wifi name at that stage?

@BHH The Deco is not aware that a Range Extender is present. You have only to configure the Range Extender.

@Rembrandt3 You want to change the wifi password? To rename a Deco unit, in the app: - tap on the map of Deco - tap on "show list" - tap on a unit - tap on the name of the unit - you can now update...

@todi What model is the ax1500 router?

@Don58 I believe you can, it is explained here. What benefits do you expect by using a Deco instead of the Sky modem?
