Selecting a Wireless Channel
You may need to change the wireless channel on which the DVW326 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
Using the Wireless Radio Option on

.
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.

Network Range
Wider range than the 5GHz band
Interference
Higher interference levels compared to the 5GHz band, as many wireless
devices such as cordless phones, microwave ovens, and computers use the
2.4GHz 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.
Band
2.4GHz
