I had an odd experience that my home network seemed to suddenly stopped connecting to my WiFi network.
I've gone through multiple attempts in restarting the HomePods, my Apple TV and of course my modem and router. My iPhone and other devices connect to the network without any problems.
I did a complete reset on my Apple TV and HomePod and they still can't connect to the network?! In fact, I can't setup my Apple TV now as a result.
Any suggestions on how to progress?
