@ThorB thanks for the fast reply :) I've downgraded as well but was just hoping some official statement from TP-Link mentioning they made a flaw instead of us doing trial-and-errors on old firmware...

I'm having the same problems and would like to get updated aswell regarding the solution. Also.. has the firmware been taken out? Can't download it any longer and Omada controller doesn't advertise...

@ThorB Having the same problem with the EAP650-Wall. Also the firmware seems to be not downloadable any longer?
