The current firmware only have WPA2-PSK[AES] + WPA-PSK [TKIP] as the nearest possible connection for legacy device. I have the printer that uses WPA-PSK [AES], the older TP-Link C7 AC1750 can use both AES/TKIP interchangeably instead of this new deco that doesn't let you have more choices.

Basically the wifi doesn't work as router uses WPA-PSK [TKIP] encryption while printer can only read WPA-PSK [AES] encryption.

Right now I am using the older router alongside the new router but that defeated the purpose of having one single network.

I like that it's easy to use but I also see the company just release another hardware update for x20, why? I don't want to get another router to just tinkering around. The new firmware should add more encryption option and separate network for 2.4ghz and 5ghz and also different banding channel.
