Your Mac WiFi keeps dropping or disconnecting
macOS stores WiFi settings in files that become corrupted after updates. We'll delete these preference files and let macOS create fresh ones. This fixes most persistent drop issues.
After macOS updates or power interruptions, WiFi preference files become corrupted. This causes repeated disconnections. Deleting these files forces macOS to create fresh ones when you reconnect, which solves the problem.

Skip, I just want a technicianCommon mistakes to avoid
- Deleting preference files and putting them in Trash instead of keeping them as Desktop backup. Keep them on your Desktop in case you need to restore them
- Restarting immediately after deleting preference files without letting macOS acknowledge the deletion first. Wait a few seconds after dragging files
- Not waiting the full 30 minutes during the stability test. WiFi sometimes takes time to show its true behavior
Signs you need professional help
- WiFi drops continue after preference file deletion and restart. Your Mac WiFi hardware appears to have failed. All Macs on your network are dropping simultaneously.
