Field

Apply channel modifications even when the network is busy

Description

Click to enable or disable this setting.

If you enable this setting, channel modifications will be applied even when the network is busy.

If you disable this setting, channel modifications will not be applied on a busy network.

This setting, along with the interference reduction setting, is designed to help weigh the cost/benefit impact on network performance of reassigning channels against the inherent disruption it can cause to clients during a busy time.

Update Advanced Settings

Click Update under Advanced settings to apply these settings.

Advanced settings take affect when they are applied, and they influence how automatic channel management is performed. The new interference reduction minimum, scheduled tuning interval, channel set, and network busy settings will be taken into account for automated and manual updates.
