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.
