Yes, I have sent two diagnostic codes, one working and one not. Just tried resetting wireless setting using the controller but that failed. It wasn't working at the time but that brought it back to life. As it happens it's showing up ok on my desktop in 'my pc' and i can browse all the folders. It shows up as being wired in my router, a TP-Link archer vr900. I have been asked by support to press the >II and the + buttons simultaneously and let them know how the LED responds.
I'll report back here with an update in case anyone else has a similar problem. At the moment it's working:D
In general, Homeplugs and similar devices aren't very reliable when it comes to Sonos speakers. They tend to lose connection from time to time. Right now, you have wireless credentials still stored on your speakers, so they may try to switch to wireless when and if the Homeplug's connection drops. It may help to either go fully wireless (in which case you may wish to change your router's wireless channel), or reset the wireless credentials on your Sonos players so they don't switch back and forth. To clear the credentials, head into the Sonos app's settings menu and look under advanced settings for wireless setup, where you can reset the credentials.
