3.9.1.3 Wireless Channel Selection
In some environments, it may be necessary to change the wireless channel on which
the wireless cable modem operates. This may especially be the case in computing
environments, test environments, and other environments where they may be several
wireless access points 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 only have control over one wireless device in
an environment where they 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 “Wireless - Radio” on
page 39.
The diagram below show the channels available for selection in the Americas. Each
available channel is 22Mhz wide. Since channels overlap, it is always 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 are one possible source for wireless
network performance issues.
