Join
Selecting an AP in the list will enable the
Join
button. The
Join
command allows
you to manually connect to a specific network. Note that to join an ad-hoc network
in this way, you must first choose ad-hoc mode through the Adapter Properties
window’s Configuration panel.
If joining cannot be accomplished within 20 seconds (possibly due to an AP that
has gone off the air since the data was last refreshed, to radio-frequency
interference, or a busy AP), the operation will fail. If this happens, you may try
joining with the same AP again, or select another AP to join.
Radio Link Quality Indicator
Clicking the InstantWave toolbar’s Radio Link Quality icon dynamically displays
the current radio signal quality (
Figure 21
). The quality level is indicated by colors.
Green means the signal is good, yellow indicates the signal is fair, red denotes the
signal is poor. When the signal color reaches the yellow to red border, the station
will start to roam, that is, try to associate with an AP that provides better signal
quality.
