Command Usage
• The available channel settings are limited by local regulations, which determine the number
of channels that are available.
• When multiple access points are deployed in the same area, be sure to choose a channel
separated by at least four channels for 802.11a to avoid having the channels interfere with
each other, and at least five channels for 802.11b/g.
• For most wireless adapters, the channel for wireless clients is automatically set to the same
as that used by the access point to which it is linked.
