I think this is a bit exotic question, but perhaps someone can help.

I have some older retro Macs (G5, iMacG4) with old WPA2 Wi-Fi cards. When I set the WAX650S connected to USG-Flex 200 to WPA3 (WPA2/WPA3-Personal) it is not possible to connect to the Wi-Fi.

Then the Wi-Fi ask for a username? and a password.

When I set the Wi-Fi to WPA2, all is working perfect, but It would be nice to use WPA3.

Any ideas?

    Hi @Tzunami,

    I'm not sure if your old MAC WiFi adapter supports WPA3. You might need to check its specifications or update its driver first. If it doesn't support WPA3, then you will need to upgrade your WiFi adapter.

    But the WPA3 has a WPA2 Fallback

    Hi @Tzunami,

    What is the security option for WPA2/WPA3-personal? If it is not 802.1X, this issue might be caused by the WiFi adaptor's driver not recognizing the SSID header correctly. It is recommended that you set a specific SSID for this device or purchase a new WiFi adaptor for WPA3.

    Hello, when you select WPA 3 or WPA2/WPA3 mode (mixed at the point), clients that do not support it connect in compatibility mode via WPA2, but older devices may not support it. Alternatively, create a separate SSID with WPA2 for older devices.

    Is it possible to allow clients from the "WPA2 SSID" only access to special IPs like a Printer via USG?

    I don't mean special Machines, i meal all who connecting to the "WPA2 SSID" are controlled by a rule. I don't see anything like this in the policy control.

    You should be able to make a new SSID mapped to a Security rule for just WPA2 devices
