Figure 7-5
Link Status Meter Screen
The Link Status Meter screen provides a graphical display of the following:
•
Signal strength—The strength of the client adapter’s radio signal at the time packets are being
received. It is displayed as a percentage along the vertical axis.
•
Signal quality—The quality of the client adapter’s radio signal at the time packets are being
received. It is displayed as a percentage along the horizontal axis.
The combined result of the signal strength and signal quality is represented by a diagonal line (see
Figure 7-5
). Where the line falls on the graphical display determines whether the RF link between your
client adapter and its associated access point is poor, fair, good, or excellent. The name, IP address, and
MAC address of the access point that is associated to your client adapter are indicated at the bottom of
the display.
Note
The access point name and IP address are shown only if the client adapter is in infrastructure mode, the
access point was configured with a name and an IP address, and Aironet Extensions are enabled (on
access points running Cisco IOS Release 12.2(4)JA or greater).
Note
The access point MAC address is shown only if the client adapter is in infrastructure mode. This field
displays the MAC address of the access point’s Ethernet port (for access points that do not run Cisco
IOS) or the MAC address of the access point’s radio (for access points that run Cisco IOS). The MAC
address of the Ethernet port on access points that run Cisco IOS is printed on a label on the back of the
device.
