MacSync-WiFi FAQs & Troubleshooting

Cannot connect to Wi-Fi​

  • Ensure the SSID and password are correct.
  • Verify that the selected frequency band (2.4 GHz or 5 GHz) matches your router’s settings.
  • Check if the router is using MAC address filtering.
  • Move the device closer to the router to improve signal strength.
  • Restart the router and the MacSync device and try again.

Wi-Fi network not appearing in scan​

  • Wait 10–15 seconds after tapping the Scan icon for networks to populate.
  • Ensure the Wi-Fi network is not hidden. If it is, use Add Network to enter SSID and password manually.
  • Confirm that your router is powered on and broadcasting the SSID.

Device keeps disconnecting from Wi-Fi​

  • Weak signal strength — move device closer to the router.
  • Check if the router is restarting or facing DHCP issues.
  • Assign a static IP address to the MacSync device.
  • Disable TWT (Target Wake Time) if it's causing instability.
  • Double-check all MQTT configuration fields:
    • Host, Port, Username, Password
    • Publish and Subscribe topics
  • Ensure the device is connected to Wi-Fi.
  • Confirm if TLS or certificate validation is required and correctly enabled.
  • Test the broker with tools like MQTT Explorer or Postman.
  • Check if the broker supports the protocol version being used.

MQTT connection test fails​

  • Make sure the MQTT broker is reachable from external devices.
  • Check for firewall/NAT rules blocking ports (1883 for unsecure, 8883 for TLS).
  • Confirm MQTT username/password and topic names.
  • If using TLS, ensure device time is accurate and certificates are not expired.

Still not working?​

  • Reboot the MacSync device and try reconnecting.
  • Reconfigure MQTT and Wi-Fi settings using the Maya app.
  • Temporarily try a public broker like test.mosquitto.org.
