Link Info Tab
The Link Info Tab displays the current state of your wireless adapter.
The fields in this menu provide the following information:
•
State: shows the association state of your computer with the
wireless LAN. When operating in Infrastructure mode, this field
shows the MAC address of the Access Point with which you are
communicating. When operating in Ad Hoc mode, this field shows
the virtual MAC address used by computers participating in the Ad
Hoc network. In both cases, the MAC address will be shown in
hex format (BSSID.) If the word scanning appears in this field, it
indicates that networking has not been achieved. The adapter is
searching for an available Access Point, within range. (Note: If
there is a problem with driver installation, this field will display an
error message.)
•
Rescan: Pressing the rescan button causes the driver to restart
and begin its connection procedure. The connection procedure
differs depending on the mode of the driver.
• Infrastructure Mode: The driver will scan all available
• Ad Hoc Mode: The driver will scan for 5 seconds looking
•
Current Channel: shows the channel on which the connection is
made. In Infrastructure mode, this number changes as the radio
scans the available channels.
•
Current Tx Rate: shows the highest transmit rate of the current
association.
•
Throughput: shows the short term transmit and receive
throughput in bytes/second, and is continuously updated.
•
Link Quality: is only active when in Infrastructure Mode. The
bar graph displays the quality of the link with the Access Point. If
the Link quality becomes "poor" the driver will begin looking for a
better Access Point. The graph will be labeled for quality as as
shown on the following page:
channels continuously until it finds one or more Access
Points that matches its SS ID. It will then try to authenticate
and associate with the Access Point.
for an existing Ad Hoc network using the same SSID. If one
is not found, the driver will "start" its own Ad Hoc network.
