If you recently changed your Wi-Fi password or moved HomePod to a new location, Siri will let you know that there's a problem connecting to Wi-Fi when you say "Hey Siri." You'll also see an alert in the Home app that says "Wi-Fi Network" on HomePod.

In iOS 12 and later, HomePod will automatically connect to the same Wi-Fi network as your iOS device. If it doesn’t, you can manually change the Wi-Fi network that it's connected to. In the Home app on your iOS device, press and hold HomePod, tap Settings , then tap "Move HomePod to [your Wi-Fi network]."

Wait a few seconds, then ask Siri a question to see if HomePod is connected to Wi-Fi.

HomePod doesn’t support captive or subscription networks. If you set up HomePod to use one of these networks, you’ll need to reset HomePod and set it up again on a different Wi-Fi network.
