I cannot setup HomePod.
I purchased HomePod about 3 three years ago. Then I used it for about 6 months. After that I did not use it about 2 and half years. I tried to setup it again. However, it always gives message 'unable to connect WiFi.' I reset the HomePod to factory setting. I also reset network setting. However, I have the same message. The ISO is different from the 3 years ago, since I am using iOS 15.5. Since I did not use it for 2 and half years, I did not update the HomePod. Please help me.
