Just got a BOOST and the setup fails every time stating that it failed to link to my account. I have tried hardwiring an existing Play1 to my router before setup, rebooted my router, reset the BOOST, and I still get the same error. Any other suggestions?
Just see if a further factory reset of the Boost (only) may work for you, the procedure for which is mentioned in this LINK, but also ensure aswell that you wire the Play:1 and the Boost direct to the router switch - do not ‘daisy chain’ their connections .. and then try the Boost setup again via Add Product in ‘System/Settings’ within the App (make sure the Play:1 is already showing in the App too).
If still no joy, then I would go onto speak with Sonos Support Staff via this LINK.
