Signal Quality
A radio frequency (RF) signal can be assessed by two components:
● signal strength (quantity)
● signal quality
The quality of the signal is determined by a combination of factors. Primarily it is composed of
signal strength and the ratio of the RF noise present. RF noise occurs both naturally and
artificially by electrical equipment. If the amount of the RF noise is high, or the signal strength
is low, it results in a lower signal to noise ratio which causes poorer signal quality. With a low
signal to noise ratio, it is difficult for the radio receiver to discern the data information
contained in the signal from the noise itself.
Signal Strength
The signal strength for all received packets. The more green bars displayed, the stronger the
signal.
Adapter MAC

CCX Version
Version of the Cisco Compatible Extensions on this wireless connection.
Current TX Power
Cisco Compatible Extensions Power Levels.
Supported Power
Levels
1.0, 5.0, 20.0, 31.6, 50.1 mW
Access Point MAC
Address
The Media Access Control (MAC) address for the associated access point.
Mandatory Access
Point
Displays None, if not enabled. If enabled, from the
Mandatory Access Point setting, the access
point MAC address is displayed. This option directs the wireless adapter to connect to an
access point that uses a specific MAC address (48-bit 12 hexadecimal digits, for example,
00:06:25:0E:9D:84).
