Hello @Lollipop, welcome to the Sonos Community!
I’m sorry to hear you are having trouble getting your Sonos Move to work after being unused for some time.
Since you’ve attempted to factory reset, it is unclear what the current status of your Sonos Move is. You might need to set up your Sonos system from scratch.
I’ll share with you a few support articles that might help you get back on track:
Connect Sonos to a new router or WiFi network
Factory reset your Sonos product
If you are still unable to resolve your issue, I suggest you contact our Support Team as they can guide you to get your Sonos Move back in action.
I hope this helps.
