If the area gets even more crowded, in an attempt to provide better coverage or to support higher
client density, you may need to take additional steps. In the following figure, notice that
z z An AP on channel 6 separates the two channel 1 APs, allowing that channel to be reused.
z z All three channel 6 APs are primarily separated by the channel 11 AP.
z z In addition to the physical placement, the power levels on the channel 6 APs have been
reduced to provide a lower radius of coverage, thus preventing these APs from touching
each other.

2.1.3 Computer Devices
Automatic wireless network configuration supports the IEEE 802.11 standard for wireless
networks and minimizes the configuration that is required to access wireless networks. When
you enable automatic wireless network configuration on your computer, you can roam across
different wireless networks without the need to reconfigure the network connection settings on
your computer for each location. As you move from one location to a new location, automatic
wireless network configuration searches for available wireless networks and notifies you when
there are new wireless networks available for you to connect to. After you select the wireless
network that you want to connect to, automatic wireless network configuration updates your
wireless network adapter to match the settings of that wireless network, and attempts to connect
to that wireless network.
Did u know? With automatic wireless network configuration, you can create a list of
preferred wireless networks, and you can specify the order in which to attempt connections
to these wireless networks.
