I am trying to setup my HomePod mini with my iPhone 11. I keep getting the message the current Wi-Fi is incompatible with the current setup. What do I do?

See:  if you can't set up HomePod. Re the following:

Check your Wi-Fi connection

• HomePod uses the Wi-Fi network that your iOS or iPadOS device is connected to. Use your iOS or iPadOS device to forget the Wi-Fi network, then join the network again. 
• Personal Hotspots might work, but aren't recommended.
• If you're using an 802.1X Wi-Fi network, learn which networks are supported and how to connect to them. 
• HomePod doesn't support public or subscription networks with sign-in requirements. These networks are often in places like businesses, schools, dorms, apartments, hotels, and stores.
