Implicit Disassociation Operations

The miniport driver performs an implicit disassociation operation after the 802.11 station has successfully connected to a BSS network and one of the following occurs:

  • The miniport driver performs an association operation by reassociating with the same AP or peer station.

  • The miniport driver performs an association operation with another AP during a roaming operation.

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

In all situations, the operating system assumes that the 802.11 station is implicitly disassociated from the AP or peer station when the miniport driver makes the NDIS_STATUS_DOT11_ASSOCIATION_START indication during the start of the association operation. For more information about the association operation, see Association Operations.

Whenever the 802.11 station implicitly disassociates from an AP or peer station, the miniport driver must not make the NDIS_STATUS_DOT11_DISASSOCIATION indication.

If the authentication algorithm that was used on the association requires port authorization for network access, the operating system deletes the port used for network access following the implicit disassociation. For more information about this process, see Port-Based Network Access.
