Connectivity Issue with WPA3-enabled SSID on Mobile Devices

[RLNG]

I am encountering an issue with my SSID, which has WPA3 Personal enabled with RADIUS for employee authentication. When attempting to connect my iPhone, I receive an error message stating, "Can't connect to this SSID." However, after forgetting the network and attempting to reconnect, it prompts me for my credentials, and then it successfully connects.

I have the SSID set to Auto-Join, but it eventually disconnects on its own. When I click on the SSID again to reconnect, the same cycle repeats with the "Can't connect to this SSID" error. To establish a connection, I must manually click "Join this network." which then prompts me to enter my username/password again. 

I've observed this issue on two test devices, an iPhone and an Android device, both of which support WPA3 and are running the latest firmware.

Has anyone else experienced a similar problem?

It's probably because de client's device does not support WP3, and the other features that WP3 enables as mandatory.

Remember that clients that do not support 802.11w will be rejected.

It had already been informed in your previous post.

Thank you for the response. I have iPhone 14 and from what I checked it supports all the features. Also if it didn't support the wpa3, why it would connect in the first place?

You didn't read the question here again - 

"Remember that clients that do not support 802.11w will be rejected." --> I have mentioned that the client connects but after a few hours, it automatically disconnects. I have verified the supplicant supports WPA3 & 802.11W.

I think that you need to open a support case. 😉

Certainly, but I was emphasizing that you hadn't actually read the question. It's preferable not to provide an answer simply for the sake of responding.

I have had the exact same issue, except on other devices (not Apple).  It might stay connected and work for 4 hours, and then break.  Might be 10 minutes.

I have tried WPA3 on and off for over 12 months.  I have never managed to get it to work reliably, on any firmware version (device and AP).

Do you think it's related to WPA3? Does the issue doesn't get replicated when using WPA2 in the same environment?

WPA2 works perfectly, and is what I use all day, every day.
