802.11 Wireless LAN Objects

  • Article

The IEEE 802.11 wireless LAN (WLAN) object identifiers (OIDs) are supported by versions 5.1 and later of the Network Driver Interface Specification (NDIS). Miniport drivers for IEEE 802.11 network interface cards (NICs) must support all mandatory WLAN OIDs. For some OIDs, support is recommended but not mandatory.

The WLAN OIDs are available through Windows Management Instrumentation (WMI).

The WLAN OIDs are defined in Ntddndis.h. When building a driver that supports these OIDs, include Ndis.h.

The WLAN OIDs are listed in the following table. In this table, an X in the respective column indicates that the OID supports query (Q), set (S), or indication (I) operations. The table also indicates mandatory (M), recommended (R), or optional (O) support requirements for different operating systems and for Wireless Privacy Authentication version 1 (WPA) and Wireless Privacy Authentication version 2 (WPA2).

Name Q S I Windows 2000 and Windows Me Windows XP and later WPA WPA2
