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

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.
