OID_802_11_ADD_WEP

  • Article

This object identifier, when set, requests that the miniport driver set an 802.11 wired equivalent privacy (WEP) key to a specified value.

A WEP key can be a preshared key, or a key that is provided to the NICs before use, for authentication, encryption, or both.

There are two types of WEP keys:

  • Per-client key

    A per-client key is used by the client to send information to the access point.

  • Global key

    A global key is used to send broadcast and multicast packets to all clients that are communicating with an access point. A global key can also be used to send unicast packets to and from the client. There must be a minimum of four global keys supported by the NIC.

    When this object identifier sets the same index twice, the miniport driver should overwrite the previous WEP key at that index. The underlying miniport driver and its NIC should not maintain WEP keys in permanent storage (disk, registry, flash, or other).

    WEP keys should be discarded immediately after any of the following events occur:

    • After the NIC disassociates itself from all basic service set identifiers (BSSIDs).
    • If shared key authentication using the WEP key fails.
    • When the driver is unloaded.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: Ntddndis.h.
