Troubleshooting and Considerations

  1. WiFi Channel Compatibility: The WiFi adapter used with your Daikin AC does not support the use of WiFi channels 12 and 13. If your router is set to use these channels, you’ll need to change the router settings to use a different channel within the range of 1-11.

  2. Firmware Updates: Regularly check for and install any available firmware updates for your Daikin AC and the WiFi adapter. These updates may include bug fixes, performance improvements, and additional features.
