Important  The Native 802.11 Wireless LAN interface is deprecated in Windows 10 and later. Please use the WLAN Device Driver Interface (WDI) instead. For more information about WDI, see WLAN Universal Windows driver model.

A miniport driver makes an NDIS_STATUS_DOT11_ROAMING_START indication before the 802.11 station begins a roaming operation.

The miniport driver indicates the completion of the roaming operation through the NDIS_STATUS_DOT11_ROAMING_COMPLETION indication. Every NDIS_STATUS_DOT11_ROAMING_START indication made by the driver must have a corresponding NDIS_STATUS_DOT11_ROAMING_COMPLETION indication.

For more information about the roaming operation, see Roaming Operations.

The data type for this indication is the DOT11_ROAMING_START_PARAMETERS structure:

The miniport driver can make the NDIS_STATUS_DOT11_ROAMING_START indication only after it has completed a connection operation with a BSS network. For more information about connection operations, see Connection Operations.

Before it initiates a roaming operation, the miniport driver must allocate all of the resources that it will need to make the corresponding NDIS_STATUS_DOT11_ROAMING_COMPLETION indication.

The miniport driver calls NdisMIndicateStatusEx to make an NDIS_STATUS_DOT11_ROAMING_START indication, and must pass a pointer to an NDIS_STATUS_INDICATION structure through the StatusIndication parameter. When making this indication, the driver must set the following members of the NDIS_STATUS_INDICATION structure:

  • StatusCode must be set to NDIS_STATUS_DOT11_ROAMING_START.

  • StatusBuffer must be set to the address of a DOT11_ROAMING_START_PARAMETERS structure.

  • StatusBufferSize must be set to sizeof(DOT11_ROAMING_START_PARAMETERS).



Available in Windows Vista and later versions of the Windows operating systemss.
