After updating the WLAN adapter, my unit is not visible anymore on the smartphone application

In some rare cases, the WLAN adapter does not automatically succeed in reconnecting to your home network.

Try the following:

A.  Try to re-establish the connection by switching the WLAN adapter to [AP] mode and back to [RUN] mode by pressing the [MODE] button.

B.  Start the WLAN adapter setup guide to reconfigure the WLAN adapter connection¹.

¹ The setup guide (“Add adapter”) can be accessed through the main menu.
