Frames Retried	The number of frames that were retried.
Frames Dropped	The number of frames that were dropped because of errors or
	collisions.
No ACK Frames	The number of transmitted frames that did not have their corresponding
	Ack frame received successfully.
ACK Frames	The number of transmitted frames that had their corresponding Ack
	frame received successfully.
RTS Frames	The number of request-to-send (RTS) transmissions that were

CTS Frames	The number of clear-to-send (CTS) frames that were received in
	response to a successfully transmitted RTS frame.
No CTS Frames	The number of request-to-send (RTS) transmissions that were
	unsuccessful. The access point sends CTS frames in response to the
	client’s RTS frames. This field keeps track of each time the client does
	not receive a CTS back from the access point.
Retried RTS Frames	The number of request-to-send (RTS) frames that were retransmitted.
Retried Data Frames	The number of normal data frames that were retransmitted.
Receive Statistics
Beacons Received	The number of beacon frames that were received successfully.
Frames Received OK	The number of all frames that were received successfully.
Frames Received with Errors	The number of frames that were received with an invalid checksum.
CRC Errors	The number of cyclic redundancy check (CRC) errors detected in the
	data portion of the frame.
Encryption Errors	The number of frames that were received with encryption errors.
Duplicate Frames	The number of duplicate frames that were received.
AP Mismatches	The number of times the client adapter tried to associate to an access
	point but was unable to because the access point was not the adapter’s
	specified access point.
	Note Refer to the Access Point 1 through Access Point 4 parameters
	on page 5-13for information on specifying access points.
Data Rate Mismatches	The number of times the client adapter tried to associate to an access
	point but was unable to because the adapter’s data rate was not
	supported by the access point.
	Note Refer to the Wireless Mode parameter in Table 5-3for
