I bought my two Sonos One SL Speakers separately. One speaker connected to the system beautifully, but the other (the new one) simply will not. My system consists of an Arc, a Subwoofer, a connect generation 2 (to connect my CD player) and the two speakers. I have tried all the fixes I know so far---the last one was to try to set up the new speaker with the ethernet cable. My system recognizes the new Sonos One SL (sometimes!) but then nothing happens, not even when I do restarts, etc. Can anyone advise what the next steps would be? (BTW, when I tried to connect the connect, I had a similar problem, but I was eventually able to connect to the system after about a dozen tries).
