Hi all.
This problems had plagued my enjoyment of my Sonos Move . Several helpful call to Sonos support and many BT Firmware upgrades made no difference to the temperamental connection to the Smart Hub - until today!
I simply disabled the ‘smart search’ function on the 2.4 GHz page of the Hub and set it to the suggested channel (1). Now connecting and staying connect to the Sonos MOVE. I even have the Hub using mode 1.
Does this work for others?
