Factory reset was likely a bad idea. I’d recommend that you temporarily wire your Beam to your router with an Ethernet cable, until you get the issue resolved, then you should be able to remove it. 

Thanks for your reply, i have managed to get into the beam using the app thru a old android phone and have made adjustments that way but the beam will not link up with the 2 SL1 speakers, I have tried everything i know but have now given up on this, i still can not get the app to work on the i phone, I have decided to ditch the Sonos system and have bought a Samsung sound bar to match the tv , still need to fix this as i plan to sell the Sonos system which i wish i had never laid eyes on.
