Attempting to follow the instructions for Sonos after changing my WiFi password were so frustrating, I'm motivated to waste more of my time to write this rather than move on. In short, trying to follow these instructions — https://support.sonos.com/s/article/1061?language=es — from a Mac will not work as described. There is no password prompt after the annoying search for an ethernet cable to connect one speaker to the WiFi. (Thank god I kept them since I didn't need them for the initial set up to the EXACT SAME router.) This is not the premium experience I would expect from this product.
