Click Apply to save changes or Reset to return to previously saved values. Click Reselect Channel
to force the channel selection algorithm for the AP radio to trigger, including a switch-over to a
better channel, if available. The Reselect Channel button applies only to the selected AP radio
interface.
Automatic channel
selection
Specify whether the channel is chosen when the AP is started, or whether it is
selected periodically. The time range for periodic channel selection is 30
minutes to 24 hours (1440 minutes). It is recommended that you accept the
default setting of automatic channel selection of periodic at 30 minutes.
Channel Set Determine which channels the AP scans in order to determine the best channel
for operation. If Auto-Selection is enabled, this determines the channel set for
auto-selection. The following choices are available for channel set:
Band — Select a specific band, or the system-determined band option
(recommended).
• The System determined band setting means that the system chooses the
channel list or band for each radio based on the number of AP radios, the
persona of the radio, and the channel set of any second radio in the AP. If
the radio is in AP mode, the node selects the best channel across both
bands. If the radio is in BP mode, the BP radio scans on both bands.
• If the Airgo AP is configured with two AP radios and Auto-Selection is
chosen for both, the preferred band configuration for both radios is System
determined. If both radios are in AP mode, one operates in the 2.4GHz
band and the other in the 5GHz band.
• If the band is 2.4 or 5GHz, the AP radio operates only in the specified
band. If it is set to 2.4GHz, the AP chooses only non-overlapping channels
for operation (for example 1, 6, and 11). It is not possible to set both radios
to operate in the 2.4GHz or 5GHz band.
• If both bands are selected, the AP radio chooses the best channel based on
the mode and band of the other radio on the AP (if installed).
• If a BP radio establishes a backhaul in the same band as the other AP radio,
this triggers the AP radio to change bands, provided that the AP radio is
configured for auto-selection and the system determined band.
Channel List — Enter a specific list of channels to be scanned, separated by a
single space (e.g.,1 2 6 11 13...). Overlapping channels can be specified in the
2.4GHz band.
NOTE: World mode and environment settings influence the channel and channel set
configurations. See “Global Configuration” on page 61 for information on world
modes.
