SETUP
Before you start with the entire setup procedure i suggest heading over to the official ASUSTOR support page to download the latest firmware and software versions.
The easiest and fastest way to setup the unit is to launch the control center software and double click on the NAS.
That will launch an explorer window which will guide you through all the necessary steps to setup the NAS.
After that you will need to setup the password, time zone, language and network options to proceed.
You should also create a new ASUSTOR id if you don't already have one to get official support and be able to download applications and use the cloud connect service.
