How to connect a device to AP without entering password?

Zyxel_Bella

Nebula AP do not support WPS for quick connection without a password. However, you can allow specific devices to connect directly to an SSID by using the Client Policy feature.

This will allow the specified device to connect to the SSID without requiring a password. Use this method carefully to ensure network security is maintained.

For further details, refer to the Nebula Client Policy FAQ:
