Selecting a Wireless Channel
You may need to change the wireless channel on which the DVW32CB operates when
you are in computing, test, and other environments where several wireless access points
may be operating in the 2.4GHz range.
In some cases, you may want to segment your wireless traffic where a group of devices
operates on one channel and another group operates on another channel, and so on. This
is done by configuring the channel on each wireless access point individually (if you have
multiples). If you have control over only one wireless device in an environment where
there may be several, you can change the wireless channel on your device to one that is
not heavily used.
Note
To change the wireless broadcast channel, refer to

.
2.4GHz Channels
The following diagram displays the channels available in the Americas. Each available
channel is 22MHz wide. Since channels overlap, it is best to choose channels that have
the least overlap (typically 1, 6, and 11 in the Americas, and 1, 5, 9, and 13 in Europe).
Overlapping channels can cause wireless network performance issues.
Band
2.4GHz
5GHz
Channels
In the USA, channels 1-11 are used. There
are 3 non-overlapping channels (1, 6, and
11). Auto channel should be selected to
ensure that the channel with the least
interference is used.
23 non-overlapping channels.
Standards

Network
Range
Wider range
Shorter Range
Interference
Higher, as many wireless devices such as
cordless phones, microwave ovens, and
computers use the 2.4GHz frequency.
Lower chance of picking up interference
because fewer types of wireless devices
use the 5GHz frequency.
Application
Recommended for simple Internet
browsing and email, as these applications
don’t take too much bandwidth and work
fine at a greater distance.
Recommended for applications that
require uninterrupted throughput, like
media streaming. The wider spectrum
delivers better performance.
Note:
If you want to use the 5GHz frequency, all wireless client adapters must support 5GHz.
