# @ohos.enterprise.wifiManager (Wi-Fi Management)

The **wifiManager** module provides Wi-Fi management capabilities for enterprise devices, including obtaining the Wi-Fi status.

> **NOTE**
>
> The initial APIs of this module are supported since API version 12. Newly added APIs will be marked with a superscript to indicate their earliest API version.
>
> The APIs of this module can be used only in the stage model.
>
> The APIs of this module can be called only by a [device administrator application](../../mdm/mdm-kit-guide.md#introduction) that is enabled.
>
> The global restriction policies are provided by **restrictions**. To disable Wi-Fi globally, see [@ohos.enterprise.restrictions](js-apis-enterprise-restrictions.md).
