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.
