Maybe try forgetting the wifi network in your settings and reset it back up @Weatherman
Have you had the opportunity to latch to another source of Wi-Fi to see how that goes ?

Daily Driver > Samsung Galaxy s²² Ultra 256Gb in Phantom Black.
The advice I offer is my own and does not represent Samsung’s position.
I'm here to help.
I have exactly the same problem with S20 Ultra and Asus Lyra network. Dropping connection and refusing to reconnect. Saying Authentication Error bur there is nothing wrong with the setup or passords.
But as soon as I move closer to the main Lyra it will reconnect. As long as I am close to a satellit Lyra it does not reconnect.
Other devices including a Samsung S8 does not have any problems.
