The BRIDGE power supply is a key suspect in this drama. Assume that it’s power supply is defective until proven otherwise. If you can measure voltage, it should be slightly over 5V. Less than 5V there will be intermittent, difficult to describe issues. Another test would be to power down BRIDGE and wire another unit.

Thanks so much for your suggestion. I will measure the voltage, and also swap the bridge at work and home and see what happens.

Be careful simply swapping BRIDGE between home and office. BRIDGE is part of a specific “Household”. Unless home and office systems use the same Houshold ID, you cannot simply swap units. You would need to Factory Reset the traveler and Add it to the system as a new unit.

It would be easier to skip the BRIDGE by wiring an Ethernet cable between your router and one of the other Sonos speakers. If the system starts to work properly, you’ve confirmed @buzz s theory. You then could choose to replace your BRIDGE with a BOOST, or just leave another Sonos device wired, or even switch the entire system over to your Wi-Fi network, as outlined in the wired and wireless modes FAQ.

Thank you both so much for your help. It was the power supply. Now fixed and able to enjoy music again. The world needs more awesome people like you two.

Just signed up with Spotify but can’t connect properly to my sonus 

Sorry to hear that you’re having this challenge, but you haven’t provided any information substantial enough for anyone to build a mental image of your system, or what process you’re attempting to use, or where the process is breaking down, in order to give you any valuable direction.

You may want to call Sonos Support directly to discuss it.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.
