Native 802.11 Extensible AP MIB objects


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.

Some of the Extensible Access Point (ExtAP) object identifiers (OIDs) are used to reference Extensible AP management information base (MIB) objects.

ExtAP objects are attributes of the IEEE 802.11 media access control (MAC) layer. The miniport driver must set these MIB objects to their default values whenever any of the following occur:

  • The miniport driver's MiniportInitializeEx function is called.
  • A method request of OID_DOT11_RESET_REQUEST is made to reset the MAC layer of the 802.11 station and the bSetDefaultMIB member of the DOT11_RESET_REQUEST structure is TRUE.

The following table lists the ExtAP OID name and the corresponding ExtAP MIB object name. For more information about an ExtAP MIB object, refer to the topic for the specific ExtAP OID.

ExtAP OID name Extensible AP MIB object name
OID_DOT11_ADDITIONAL_IE msDot11AdditionalIEs
OID_DOT11_AVAILABLE_CHANNEL_LIST msDot11AvailableChannelList
OID_DOT11_AVAILABLE_FREQUENCY_LIST msDot11AvailableFrequencyList
OID_DOT11_WPS_ENABLED msDot11WpsEnabled

Unless an ExtAP MIB object defines a specific default value, the Native 802.11 miniport driver defines its own default value for the MIB object.


When the miniport driver receives an OID_DOT11_RESET_REQUEST method request the miniport driver must reset an ExtAP MIB object to its default value under the following conditions:

  • When MIB values for the MAC and/or PHY are reset to their default values only if bSetDefaultMIB is set to TRUE.
  • When MAC or PHY values are affected by the value of the dot11ResetType member. For more information, refer to the topic for the specific ExtAP OID.
