I have two controlers at different locations that appear to be showing the same or similar issues. 

For a week or so now, my devices have been disconnecting from the wifi, ive mainly noticed this with my phone (pixel 7 pro) but it has happened to other devices. if i try to reconnect I get a message that the password is incorrect, ive hit the retry button over and over, but I get the same wrong password message. Eventually the phone connectes with no change to the password. It will eventually drop off again with the same error, and will connect or not connect at random thorugh the day. Ive tried resetting and upgrading the clients, Ive checked that im at latest versions of the OMADA devices and controllers but i cant see whats causing this althoguh i suspect it was a recent firmware installation on the OC200.

The dashboard does sho 128 association failures for one of my omada AP's and none of the others seem to have any, if this could be related.
