I have tested wpa2/wpa3 mixed mode sae and eap (enterprise) and have seen wpa2 working and wpa3 clients stepping down to wpa2 making it useless. What I have also read is to never have two ap’s on the same radio with different security schemes which I tested and found it not to be necessary but actually worked fine. please don’t take my word for it but please test yourself incase my testing was in correct cause i really diddn’t believe it myself. maybe a new enhancement in 19.07.x? Note no mixing enterpise because that defaulted to enterprise
