Power Level
The following channel setting options exist:
User Selection - If selected, use the drop-down menu to specify
the legal channel for the intended country of operation. The drop-
down menu is not available if this option is not selected.
Automatic Selection - When the access point is booted, the
access point scans non-overlapping channels listening for beacons
from other access points. For 802.11b, it scans channels 1, 6, and
11. For 802.11a, all channels are non-overlapping. After the
channels are scanned, it will select the channel with the fewest
access points. In the case of multiple access points on the same
channel, it will select the channel with the lowest average power
level.
Select the Exclude Channels
prohibit 802.11a or 802.11b/g channels from operating with this
radio. When channel exceptions are defined, the access point skips
the channels specified. When the Automatic Selection feature is
enabled, up to 3 separate channels can be excluded. Imported and
exported configurations retain their defined exception list
configurations. The channels selected for exclusion display
beneath the Uniform Spreading button. This option is disabled by
default. It's important to note that excluded channels do not apply
to sensor scans or rogue detection configurations. Additionally,
country of operation blocks are not impacted by the channels
selected for exclusion. A reboot is required when enabling or
disabling this feature.
