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.

When set, the OID_DOT11_ASSOCIATION_PARAMS OID requests that the miniport driver append a list of additional information elements (IEs) to the association request that the NIC sends to an access point in an infrastructure BSS network.

Note Support for this OID is mandatory.

The data type for this OID is the DOT11_ASSOCIATION_PARAMS structure.

When this OID is set, the NIC must behave as follows:

  • If the ExtSTA is in the INIT state, the NIC must complete the request.

  • If the ExtSTA is in the OP state, the NIC must fail the request and return error code NDIS_STATUS_INVALID_STATE.

The NIC should place additional IEs at the end of the association request unless the additional IEs would cause the size of the frame to exceed the MAC management protocol data unit (MMPDU) limit. In this case, the NIC can discard the new additional IEs.

If the additional IEs are successfully added to the association request, the miniport driver should include these additional IEs in the association request frames that it reports in the DOT11_ASSOCIATION_COMPLETION_PARAMETERS structure.

The miniport driver should clear its copy of the information in the association request if the bSetDefaultMIB member of the DOT11_RESET_REQUEST structure is TRUE and an OID_DOT11_RESET_REQUEST method request is made to reset the MAC layer of the 802.11 station.



Available in Windows 7 and later versions of the Windows operating systems.
