AX3000 router     Why is there a red light on myn router .  second from them top

[FURRYe38]

What router model do you have? AX3000 isn't a model #

What does the user manual day about LED behavior? 

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.
