I have had multiple Sonos speakers in the house for years, always worked perfectly without any issues. I decided to add two play 1 speakers to a room we watch TV the most in. Wanting more of a surround sound system. I power up both speakers, lights turn green. The sonos ap on my ipad recognizes both speakers, giving me their serial numbers, but when I go to add them to the system it gives me an error. Saying that the speaker is not found? I have even plugged them into the router via ether net cable as suggested. I have attempted this process at least 10 times. Not working. Seems odd to me that they system sees the speakers, but then can’t connect. Any help would be greatly appreciated.
