Extensible Access Point Indications

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 a miniport driver operates in Extensible Access Point (ExtAP) mode, it can make the following status indications that are specific to ExtAP mode:

Name Description
NDIS_STATUS_DOT11_CAN_SUSTAIN_AP The driver makes this indication after the NIC stops an 802.11 access point (AP).
NDIS_STATUS_DOT11_INCOMING_ASSOC_COMPLETION The driver makes this indication after either a successful or failed incoming association request from a peer station. For more information about Association operations in ExtAP mode, see Association Operation Guidelines for Extensible Access Point (ExtAP) Mode.
NDIS_STATUS_DOT11_INCOMING_ASSOC_REQUEST_RECEIVED The driver makes this indication after the NIC receives an incoming association request frame from a peer station. For more information about Association operations in ExtAP mode, see Association Operation Guidelines for Extensible Access Point (ExtAP) Mode.
NDIS_STATUS_DOT11_INCOMING_ASSOC_STARTED The driver makes this indication when the NIC receives the first valid 802.11 authentication request from a peer station. For more information about Association operations in ExtAP mode, see Association Operation Guidelines for Extensible Access Point (ExtAP) Mode.
NDIS_STATUS_DOT11_PHY_FREQUENCY_ADOPTED The driver makes this indication after it has adopted a channel or frequency to communicate with a peer station.
NDIS_STATUS_DOT11_STOP_AP The driver makes this indication when the NIC cannot sustain 802.11 access point (AP) functionality on any of the available PHYs.

Additionally, a miniport driver operating in ExtAP mode can makethe following status indications:

Name Description
NDIS_STATUS_DOT11_DISASSOCIATION The driver makes this indication after the 802.11 station completes a disassociation operation with an AP or peer station. For more information about this operation, see Disassociation Operations.
NDIS_STATUS_DOT11_LINK_QUALITY The driver makes this indication whenever the 802.11 station determines the link quality for an association with an AP or peer station that has changed significantly. For more information about link quality and link quality indications, see Link Quality Operations.
NDIS_STATUS_DOT11_PHY_STATE_CHANGED The driver makes this indication whenever the power state changes on a PHY that is supported by the 802.11 station.
NDIS_STATUS_DOT11_TKIPMIC_FAILURE The driver makes this indication whenever a received packet that has been successfully decrypted by the TKIP cipher algorithm fails the message integrity code (MIC) verification.
