Problems with WiFi connection WPA 3 802.1 x

[asvintsov]

On new laptops with Win 10, we encountered a problem connecting to WiFi with configured 802.1 x authorization. The behavior is that if you just select the broadcast SSID and try to connect, the connection does not occur, most likely due to the fact that the laptop is trying to connect via WPA3, which we did not configure.

If you manually create a connection to the SSID specifying all the settings and authorization set WPA2 which we have configured, everything works.

Tell me, is there any recommendations for configuring WPA 3 802.1 x Wi Fi on Cisco equipment? We use WiFi controller 3504, WiFi point 2802I

Look at the "lowest common denominator" in the network.  If there are no clients able to support WPA3, do not do it.

In other words, all clients on the network must support WPA 3, only in this case it can be used on the network, otherwise wpa3 should be disabled, do I understand you correctly?

[Leo Laohoo]

Correct.

[asvintsov]

And if we have about half of our clients can use WPA3 and apparently use it by default, but there are also WPA2 clients, in this case there are some recommendations on how to configure it? In addition, we have counted and now we have more WPA-3 supporting clients.

There is a way to run both at the same time, but I really don't suggest this. This is called Transition Mode. For the moment I would run two separate SSIDs, if you really need to use WPA3.
