menu.

1. Select the Signal tab to display a real-time graph of the signal quality of the mobile

computer to the associated AP (Infrastructure Mode only). The number of times the mobile

computer has roamed to and from APs, the current data rate and the network status are

displayed. Signal quality is an indicator of how clearly the adapter can hear the associated

AP.

Table 6-10. Signal Fields

Field Description

Missed Beacons Displays the amount of beacons (uniform system packets broadcast by the AP to

keep the network synchronized) missed by the mobile computer. The fewer the

missed beacons the better the signal. As long as the LED to the right of the graph is

green the AP association is not jeopardized by an excess of missed AP beacons. If

the LED is Red, an association with a different AP could be warranted to reduce the

amount of missed beacons and improve the signal.

Txmit Retries (Transmit

Retries)

Displays the number of data packets retransmitted by the mobile computer. The

fewer transmit retries the stronger the signal. As long as the LED to the right of the

graph is green the AP association is not jeopardized. If the LED is red, an association

with a different AP could be warranted to reduce the amount of transmit retries and

improve the signal.
