@RaiderRodney I used the software update and it says the firmware is updated: 1.0.2 Build 202200630 Rel 73505 Still no means to change the Wi-Fi security.

I just installed 3 new Deco X20 and now my Apple devices are indicating "weak security" for the Wi-Fi WPA2! I cannot believe that TPLink is asking customers to install a beta version of the firmware...
