I get “The software update of the adapter has failed.” Error

Please try to update the WLAN adapter firmware minimum 2 times while the adapter is in RUN mode. In some rare cases the firmware send over your Wi-Fi connection can be corrupted.

If updating in RUN mode does not work for you, please switch the WLAN adapter to AP mode and connect your smartphone directly with your WLAN adapter (DAIKINAPxxxxx). Ensure that you are in close proximity to your WLAN adapter (Max 10 meters – Line Of Sight). Try to update the WLAN adapter again via the Daikin Online Controller application. If the WLAN adapter was correctly configured before the firmware update, the WLAN adapter will reset and should automatically reconnect to your in-home Wi-Fi network.
