Retrieving and push value

Hi, is there any way to retrieve a value from acs, for example, WiFi name and password of a device and push it again when the device comes online?

Can you clarify your request? Are you trying to set the wifi credentials on a CPE after it comes online? Or are you trying to retrieve the existing wifi SSID and passphrase and restore them?

Retrieving the wifi passphrase is not possible due to security restrictions in the specification.

When read, this parameter returns an empty string, regardless of the actual value.

Your reply is self-sufficient to my query. Thanks akcoder.
