I adopted the Deco M5 to setup Wifi in my home and i was very happy when i saw that it was going to adopt WPA 3.

Here is the comment back in 2020:Support WPA3 for all Deco mesh devices - Home Network Community (tp-link.com)
Is there any ETA for WPA3 in the Decos ?
Is is still in the plans?

The linked thread (which is locked) asked customers to be patient that it was in the works.

My concern about security is that i already got "Unknown devices" connecting to my network even tho i am Using WPA2-PSK AES and i am not sure if at the time, it was an attack or someone managed to get my wifi password.

Fact it happen again last year and i was forced to change my network including the SSID to something else and i am running with no issues for over 2 months. I even setup arpwatch in my main router to send me emails when a new device is detected.
I am even considering switching to wifi 7 devices and ditch the decos if i dont feel secure on them,
