Device won't connect - AX6000 RBR850 FW V3.2.18.1

Trying to reconnect a Netgear WNCE2001 wifi adapter to my Orbi. It has previously been connected now it doesn't show up on the connected devices. A notification is generated that a new device has been connected but there is no device indicated on the app ... clicking on the notification takes me to a page to extend the Armor subscription but that is subject of another post.

I have rebooted the Orbi and the modem numerous times in the recommended order and yet no positive result. 

As I am having similar issues maintaining connection of my Google Hub to the Orbi satellite, I am begining to regret the purchase of this +$1k product.
