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.
