  • Artikel

Important

This topic is part of the WiFiCx driver model. WiFiCx is the Wi-Fi driver model released in Windows 11. We recommend that you use WiFiCx to take advantage of the latest features. The previous Wi-Fi driver model WDI is in maintenance mode and will only receive high priority fixes.

WDI_TLV_CONNECTION_SETTINGS is a TLV that contains connection settings for OID_WDI_TASK_CONNECT.

TLV Type

0x3F

Length

The sum (in bytes) of the sizes of all contained elements.

Values

Type Description
UINT8 Specifies if this is a first-time connection request (value of 0) or a roaming connection (value of 1).
UINT8 Specifies if this is a connection to a network with hidden/non-broadcast SSIDs. This value is 1 when connecting to a hidden network.
UINT8 This sets the dot11ExcludeUnencrypted MIB. When this value is false (0) and the cipher algorithm is WEP, the port must connect to APs that do not set the privacy field in management frames.
UINT8 Specifies if MFP is enabled (1) or disabled (0). The station must advertise its 802.11w capabilities in the association request if and only if this value is set to 1 (enabled).
UINT8 Specifies if host-FIPS mode is enabled (1) or disabled (0).
WDI_ASSOC_STATUS (UINT32) Specifies the roaming needed reason. If this is triggered due to NDIS_STATUS_WDI_INDICATION_ROAMING_NEEDED, this contains the reason from the roam indication.
WDI_ROAM_TRIGGER (UINT32) Specifies whether this roam is a critical roam because the AP has set the Disassociation Imminent bit in its BSS Transition Request action frame.
UINT8 Specifies if 802.11v BSS transition is supported. If this bit is set to 1, the Station must set the BSS Transition field of the Extended capabilities element (Bit 19) to 1 in the association request.
UINT8 The MloConnectionSupported flag that specifies if Multi-Link Operation (MLO) connection is supported.
UINT8 Specifies if this is a FIPS mode connection. The station must use only certified cipher algorithms if HostFIPSModeEnabled is false (for example, when hardware FIPS support is used).
UINT8 The MSCSSupported flag specifies if the OS supports MSCS for this connection. If set to 1, the IHV driver must set the Mirrored SCS field of the Extended Capabilities element (Bit 85) to 1 in the association request.
UINT8 The DSCPToUPMappingSupported flag specifies if the OS supports QOS Mapping for this connection. If set to 1, the IHV driver must set the QoS Map field of the Extended Capabilities element (Bit 32) to 1 in the association request.
