HomePod wifi

Ah, my sincere apologies, I didn't understand the apartment co-op Wifi part of your post. It is a limitation to the HomePod mini. Unfortunately I am aware of no supported way for HomePod to connect to a Wifi network that has a sign in requirement. But it may not hurt to call Spectrum to see if they have a way.

Edit: one item I forgot to mention, if you use a non sign in required Wifi network one time to setup the HomePod, you can then Airplay music to it from your iPhone (even though HomePod is not connected to a network).

Hi Dgrainger, I don't know Spectrum Subscription Wifi, however, it doesn't allow your various devices to join the Wifi network with the password? The HomePod mini to best of my knowledge will provide the Wifi password.

If your Wifi router is managed by Spectrum and devices aren't allowed on the Wifi network without, I'm guessing, providing them a MAC address(?), contact https://www.spectrum.net/support and provide them the MAC address from the HomePod mini. (If you go into the Home app, long press HomePod button, press speakers, press the HomePod button, this will show you your HomePod MAC address).
