I set up a network at my new house using all new speakers. I now want to add a Play 5, a connect and a connect AMP. When plugging in the new (old network) speakers I obviously do not get the green LED so cannot add to the system. Is a full reset of the previous network speakers the best way to go? If so, do I have to reconnect to my old house wifi or can it be done at the new place. Any guidance much appreciated.
