Channels available depend on your geographical area. You may have a choice of channels (for your
region) so you should use a channel different from an adjacent AP (access point) to reduce
interference. Interference occurs when radio signals from different access points overlap causing
interference and degrading performance.
Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should
be on a channel at least five channels away from a channel that an adjacent AP is using. For
example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to
select a channel between 6 or 11.
