Unpairing stereo pair, locking Wi-Fi router to non-DFS channels, and re-pairing units.

Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

  1. Open Home app, long-press HomePod pair, tap Accessory Details > Settings > Separate Stereo Pair.
  2. In your Wi-Fi router admin panel, assign a fixed 5GHz channel (e.g. Channel 36 or 44) instead of Auto-DFS.
  3. Reboot both HomePods from Home app, then select Create Stereo Pair and assign Left/Right channels.

Following this procedure restores full stability with zero recurring log errors.
