SETUP

The initial setup screen gives you two choices either to allow the wizard to download the latest firmware version on its own or download the firmware yourself and perform a manual installation (this is what i recommend).

You can download the latest firmware version from the official QNAP support page as seen above.

After that you need to choose either the quick setup that makes most changes on its own or the manual one which requires more interaction from your end (as usual we recommend the manual setup).
