Setup failed -6722 - Solved

Had a difficult time connecting to the HomePod initially.

This is what worked for me. I disconnected all Bridged extenders (apple) and then rebooted by Airport Extreme Core and rebooted my Iphone 7 (latest software). Through Iphone and Bluetooth, I was able to connect to the HomePod easily and smoothly.

Network setup - Internet --> Airport Extreme Core ----> Bridge Airport Base / Bridge Airport Extreme / Bridge Airport Extreme.

Note:

- Cable modem connected to the Airport Extreme Core and the rest are bridge extenders for Excellent signal throughout the house.

The sound on this HomePod is amazing.. worth the buy !!! Love that smooth crisp Bass !!!
