Hi, 
To better help you, please help to confirm the following information.
What's the device are you used to connect to the Deco's Wi-Fi with WPA3 security type? What's the model number of the wireless adapter on that device?
How do you manually join the Deco network using WPA3?

Hi,

i have tested 3 devices, an iPhone 11 Pro, Macbook Pro 2020, and a Gaming PC with an Intel AX200

When selecting a network, if you select hidden network  it will give an option to select WPA3. as stated, another router i have tested had NO issues with WPA3.

This can rule out any client issues.

Hi! I discovered the WPA3 option based on your post, so I thought I would test it and see if I have the same issue as you. First WPA2 was used, but after making the client "forget" the wifi network and set it up again both my Samsung S10 and my Surface laptop are now using WPA3. Thanks for making me aware of this option.

Hi, I'm glad it worked for you!

I noticed my PC is now using WPA3, which is great, however all my other clients still have issues with the Deco's WPA3 implementation where all my tested clients were very happy with WPA3 on the ASUS router I mentioned in my OP

Hi, 

When your other devices connected to Deco's network using WPA3, what's the error message do you have on your other devices?
Have you tried to forget the Wi-Fi network and then connect to it again on your clients such as iPhone, MAC laptop?

Hi, attached is an error message from my iPhone, i have tried forgetting network already.

I would like to reaffirm that I have tested another router with WPA3, and my client devices never had a problem, the red herring here is the Deco unit.
