Table 7-3 Client Adapter Status Screen Parameters (continued)

Parameter	Description
Using MIC	Indicates whether your client adapter is using message integrity check
	(MIC) to protect bit-flip attacks on encrypted packets. During a bit-flip
	attack, an intruder intercepts an encrypted message, alters it slightly,
	and retransmits it, and the receiver accepts the retransmitted message as
	legitimate. The following drivers support MIC:
	• Mac OS 9—version 1.0.3 or greater
	• Mac OS X—version 1.0.1 or greater
	MIC is used only if it is enabled on the access point.
	Note If the access point is using MIC, your client adapter’s driver and
	firmware must support MIC; otherwise, the client cannot
	associate.

	Values:
	Yes—client adapter radio is MIC capable, MIC is enabled on
	the access point, and MIC is being used.
	No—client adapter radio is MIC capable, MIC is enabled on
	the access point, but MIC is not being used.
	N/A—client adapter radio is not MIC capable.
	Disabled—client adapter radio is MIC capable, but MIC is
	disabled.
MIC Errors	Indicates the total number of MIC errors that have occurred.
Signal Strength	The signal strength for received packets. The longer the bar graph is, the
	stronger the signal.
Signal Quality	The signal quality for received packets. The longer the bar graph is, the
	better the signal quality.
Network Name	The network name or SSID of your wireless network.
	Note Refer to Table 6-1for information on setting your wireless
	network’s network name.
Name	The name of the access point to which your client adapter is associated.
	It is shown only if the access point was configured with a name and you
	are in infrastructure mode.
MAC Address	The MAC address of the access point or wireless device to which your
	client adapter is associated.

Assessing the Wireless and Wired Links

You can determine the operation of the wireless and wired links from your client adapter in two different ways:

•You can use the link status meter to view a graphical display of the signal strength and quality of the radio signals from the local access points (configured for broadcast SSID). Go to the “Viewing the Link Status Meter” section below.
