Set Information Functions

AddWep()

Call this function to add a WEP key to the radio. Call this function multi-

ple times when adding more than one WEP key. Save the “default” key for

last. For example, when adding four keys, and the second key is the default

transmit key, add keys 1, 3 and 4 before you add key 2.

Note: Add the default transmit key last.

Syntax UINT AddWep( ULONG, BOOL, TCHAR * );

Parameters ULONG Specifies the key index to be set. Valid values are 0-3.

BOOL When set to TRUE, specifies that this key is the default transmit key.

TCHAR Pointer to a character array that specifies the key data in either HEX (length of 10

or 26) or ASCII (length of 5 or 13). This string must be null-terminated.

Return Values ERROR_SUCCESS when successful, ERR_QUERY_FAILED when the query failed, or

ERR_CONNECT_FAILED if a connection with the radio failed.

Remarks When adding WEP keys to the radio, turn off encryption before you add the keys, then turn encryp-

tion back on afterwards. Also, be sure to add the TRANSMIT KEY last.

Definitions #ifdef DYNAMIC_LOADING

typedef UINT (*PFN_AddWep)(ULONG, BOOL, TCHAR *);

#else

UINT AddWep(ULONG, BOOL, TCHAR *);

#endif

EnableWep()

Enables or disables WEP encryption on the radio (TRUE/FALSE).

Syntax UINT EnableWep( BOOL );

Parameters Set BOOL to TRUE to enable WEP encryption, or FALSE to disable

WEP encryption.

Return

Values

ERROR_SUCCESS when successful, ERR_QUERY_FAILED when

the query failed, or ERR_CONNECT_FAILED if a connection with

the radio failed.

Remarks Call this function with TRUE as the parameter to enable WEP encryp-

tion. Call this function with the FALSE parameter to disable WEP

encryption. This call is an alias for EncryptionStatus(). See the following:

EnableWEP(TRUE) = EncryptionSta-

tus(NDIS_ENCRYPTION_1_ENABLED)

EnableWEP(FALSE) = EncryptionSta-

tus(NDIS_ENCRYPTION_DISABLED)

Definitions #ifdef DYNAMIC_LOADING

typedef UINT (*PFN_EnableWep)(BOOL);

#else

UINT EnableWep(BOOL);

#endif
