CONFIGURATION UTILITY

Throughput

These two fields display the instantaneous wireless Receive and Transmit throughput displayed in bytes per second. These values are updated every two seconds.

Link Quality

The Link Quality bar graph is only active when the node is in Infrastructure Mode. The bar graph displays the quality of the link between the node and its Access Point. A label summarizes the quality of the link over the bar graph, which can take on one of the following values:

"Not Applicable" "Poor"

"Fair"

"Good"

"Excellent"

The wireless adapter will start looking for a better Access Point if the Link Quality becomes "Poor". Link Quality is a measure of receive and transmit errors over the radio channel.

Signal Strength

The Signal Strength bar graph is only active when the node is in Infrastructure Mode. The bar graph displays normalized signal strength as reported by the radio, averaged over all frames over 100 bytes long that are received from the Access Point.

Configuration Tab

The Configuration Tab contains several fields where the operating parameters of the wireless can be viewed and changed. Changes to any of the parameters in the panel can be applied to the wire- less adapter without the need to reboot the PC.
