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 two channels for 802.11a to avoid having the channels interfere with each other, and at least five channels for 802.11b/g. You can deploy up to four access points in the same area for 802.11a (e.g., channels 36, 56, 149, 165) and three access points for 802.11b/g (e.g., channels 1, 6, 11).
•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.
