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 five channels for 802.11b/g. You
can deploy up to 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.
Example
transmit-power
This command adjusts the power of the radio signals transmitted from the access
point.
Syntax
transmit-power <signal-strength>
signal-strength - Signal strength transmitted from the access point.
