There's a support site with access to manuals, firmware, install guides, etc. Go to https://www.netgear.com/support/ Type in your model number and from there it'll take you to the above. Its a great resource to start with.
I have successfully registered my Netgear AC600 but do not know how to proceed in the set up process. Please help
AC600 is not a reliable guide to model number. Many devices come with an AC tag, but it is essentially a label that Netgear, and other brands, attach to hardware to describe wifi speeds.
Look at the label on the device for the model number.
Then check the support pages for that device. That will usually reveal a Quick Start guide that tells you how to set it up.
