Deploying and Troubleshooting the Wireless Network

Selecting a Wireless Channel

You may need to change the wireless channel on which the DDW365 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 

page 63

.

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.
