Forgot to mention its a Sonos One system 

So what is its state - is it still setup for the router in Hong Kong or has it been reset to factory settings?

Does the new router/network meet the current Sonos System requirements?

Does your ‘mobile’ controller App (S2, presumably?) meet these requirements?

You may also find this Sonos support link helpful if you have not reset your Sonos product…

Just to confirm, the only difference between a Sonos product sold in Hong Kong and one sold anywhere else is the power cord. There is zero difference in the internal electronics. 

Trying to connect my Sonia Move to  Bluetooth and when I press the button at the back I do not get a “chime”

please help! Thanks
