Why am I getting the message "The network adapter currently in use is not authorized to receive the updates" (error 3101)?

This is how you enable your Wi-Fi network for G DATA updates:

1

Open the G DATA software and click on "Last Update" > "More settings…​".

2

Select "Manage access" in the settings window.

3

If the internet connection you are using is listed under the blocked networks, select it and move the network to the allowed accesses using the arrow.
