AX4 WiFi 6 router connection problems and drop out.

You have really just repeated what we already knew, but at greater length. We still do not know what you are doing and what happens.

Let;'s go through it.

What are you doing and what happens when you try?

Can your phone see the router's SSID? What ha[ppens when you try to log in?

Does it reject the password? Does it show any other messages?

Likewise, does the laptop throw up any messages when you try to connect?

Can these devices connect to different wifi sources?

Is this a Windows laptop?

What does that mean? Where do you see messages saying that?

What is this Netgear app? There are lots of them.

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. The model number could be useful. Is it, by any chance, also a router, with a set of LAN ports on the back?
