GetTXPower()
Call this function to get the current transmit power of the radio.
Syntax UINT GetTXPower( ULONG & );
Parameters NDIS_POWER_LEVEL_63 63 mW
NDIS_POWER_LEVEL_30 30 mW
NDIS_POWER_LEVEL_15 15 mW
NDIS_POWER_LEVEL_5 5 mW
NDIS_POWER_LEVEL_1 1 mW
NDIS_POWER_LEVEL_UNKNOWN Unknown Value or Error.
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 If ERROR_SUCCESS is returned, your ULONG reference is populated with the TX power in mil-
liwatts (mW). Valid ranges are from 5 mW to 100 mW.
Definitions #ifdef DYNAMIC_LOADING
typedef UINT (*PFN_GetTXPower)(ULONG &);
#else
UINT GetTXPower(ULONG &);
#endif
GetWepStatus()
Call this to get the current state of the radio’s WEP and encryption levels.
Syntax UINT GetWepStatus( ULONG & );
Parameters NDIS_ENCRYPTION_1_ENABLED WEP enabled; TKIP, AES not enabled, and
transmit key may or may not be available.
NDIS_ENCRYPTION_DISABLED Indicates AES, TKIP, WEP disabled, and trans-
mit key available.
NDIS_ENCRYPTION_NOT_SUPPORTED Indicates WEP, TKIP, AES not supported.
NDIS_ENCRYPTION_1_KEY_ABSENT Indicates AES, TKIP, WEP disabled, and trans-
mit key not available.
NDIS_ENCRYPTION_2_ENABLED Indicates TKIP, WEP enabled; AES not enabled,
and transmit key available.
NDIS_ENCRYPTION_2_KEY_ABSENT Indicates no transmit keys available for TKIP,
WEP, TKIP, WEP enabled; AES not enabled.
NDIS_ENCRYPTION_3_ENABLED Indicates AES, TKIP, WEP enabled, and trans-
mit key available.
