GetDiversity()

Call this function to get the current diversity setting of your 802.11b/g radio. This function uses an optional NDIS5.1 OID to query the radio, which a large number of 802.11b/g devices do not support. This function may be inaccurate.

Syntax	UINT GetDiversity( USHORT * );
Parameters	ANT_PRIMARY	The primary antenna is selected.
	ANT_SECONDARY	The secondary antenna is selected.
	ANT_DIVERSITY	The radio is in diversity mode, and uses both antennas

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 USHORT reference is populated with one of the parameters
	listed above.
Definitions	#ifdef DYNAMIC_LOADING
	typedef UINT (*PFN_GetDiversity)(USHORT *);
	#else
	UINT GetDiversity(USHORT *);
	#endif

GetLinkSpeed()

Call this function to get the current link speed of the 802.11b/g radio.

Syntax	UINT GetLinkSpeed( int & );
Parameters	This function accepts an int reference, and your int is populated with the
	current link speed, in Mbps, rounded to the nearest whole integer, for
	example: 1, 2, 5, 11, etc.
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	Data returned is valid if ERROR_SUCCESS is returned.
Definitions	#ifdef DYNAMIC_LOADING
	typedef UINT (*PFN_GetLinkSpeed)(int &);
	#else
	UINT GetLinkSpeed(int &);
	#endif
