Captive portal set up, but guest wifi prompts password

Hello,

I have X750 spitz here and running 3.217 firmware.

Guest wifi is enabled on 2ghz and 5ghz. When I enable captive portal, I am expecting that I should be able to join either SSID without password authentication, however, when I try to join on Windows or Mac, I am prompted to enter a password. This does not happen on iOS.

Any help would be much appreciated.

May I know if the guest Wi-Fi configured the password key on the router?

What password required to input to join that guest Wi-Fi?

The default password on the back of router is accepted and the guest wifi password is configured when it is toggled on.

Probably is that password you set-up when enabled guest WiFi?

May can select the 'Open' without the WiFi password.
