I have speakers running in a business environment. We are streaming audio and sometimes we loose certain speakers. Not always the same speakers. The problem seems to move around. I thought access point but the speakers that go out are connected to the same access point. Someone had a similar issue in their home and suggested there was a special router offered or recommended by Sonos that solved their problem in their home. Eero Pro 6 routers. Guest network setup. Speakers and all business equipment on the business side, not guest login.
