I’m continuously getting “Configuration Error” - router cannot apply your new settings. Occurs when trying to update wifi security level. Have rebooted and factory reset both modem and router several times.
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.

Where are you updating the wifi settings? Which bit of the browser graphical user interface (GUI)?
What firmware version do you have on the device?
A number is more useful than "the latest". (It may not be by the time people read this.) There can also be newer versions, or "hot fixes", that do not show up if you check for new firmware in the browser interface.
It might also help if you told people what the modem is in front of this router, if there is one. The make and model number could be useful. Is it, by any chance, also a router, with a set of LAN ports on the back?
The reason for asking is that a lot of people turn up here trying to put a router behind a modem that is also a router. That can complicate troubleshooting.
I assume that you mean R6120. (There is no R6129.)
How fast is your Internet service? If it is faster than 100 Mbps. you are wasting
money.
According to Netgear's manual for this device, not always the most reliable source of information, the LAN and WAN ports support only 10BASE-T or 100BASE-TX. That makes it slower than many newer internet services and most modern network hardware.
