I was forced to change internet providers and received a new router. My ONE connects just fine, but the Play:3 says it cannot connect to the WiFi, and that I should check the password.
Now I know that Play:3 doesn't work on 5GHz, so I set up a band steering rule in my router, forcing it to connect to the Play:3 on 2.4GHz. I even did the same for the ONE and my phone (at least temporarily) to make 100% sure everything will be on the same network/frequency during set-up. To no avail.
My old router was also set to hybrid 2.5/5GHz and the Sonos products worked without issue. Am at my wits' end here. I'd really like to avoid operating separate 2.4 and 5GHz networks.
