I have a Playbar and 2 Play:1s in the TV room. I also have 2* 3s in the lounge, and 8 other units in the house. Broadband wifi ranges 50-100MBPS depending on room, its about 50 in the TV room.
Using the TV I have no issues. But playing music on the TV setup (and nothing on any other units) I get dropouts on the Play:1s every few minutes. The Playbar continues to work when the 1s drop out.
I've done all the updates, Sonos units, firmware updates of routers etc etc. No luck.
I have no issues on any other units elsewhere.
Any help appreciated!
