WiFi6(Ax1800) and WiFi 6E(AXE)

Which Netgear device do you own?

AX1800 is not a reliable guide to model number. Many devices come with an AC/AX 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.

Manuals are always a good place to start.

Visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware.

Look for the model number on the label on the device.

Check the section in the manual something like  Specify Basic WiFi Settings.

You may have done that already. I can't tell from your message.

I mention it because Netgear gave up on supplying paper manuals and CD versions some years ago and people sometimes miss the downloads.
