SETUP
Once you plug the TS-420 with your router you will need to run the Qfinder program to locate it and start the installation (that's the easy way anyways).
Prior to launching the setup wizard i strongly suggest downloading the latest firmware version to your local drive from the official QNAP support page.
The setup wizard gives you two options, quick and manual setup (we always choose manual).
After that screen you will need to set a name for the server, set the administrator user name and password (if you don't like the default ones), check and adjust (need be) the network settings and finally point to the firmware update file in your local drive (if you have downloaded one). The entire setup procedure does take quite a bit to complete (approximately 30 minutes).
Once the setup is complete you can choose to take a look at the utilities made available by QNAP.
Clicking on the green button will redirect you onto the QNAP website and a list of utilities along with a short description next to them.
