    Description

    SonicOS 6.5.4.6 provides Radio Resource Management and Dynamic Channel Selection enhancements to Access Points settings.

    Resolution

    NOTE: Radio Resource Management is supported on SonicWall access points that have a dedicated scan radio, including SonicWave 231c, 231o, 432e, 432i, and 432o. The RRM feature is not supported on SonicWave 224w or on SonicPoints.

    You can navigate to MANAGE | Connectivity | Access Points | Radio Resource Management tab to configure these options.

    Radio Resource Management and Dynamic Channel Selection Options and Values:

    Option NameDescription
    Enable Radio Resource
    Management - RRM
    Enable this option to activate the settings for Station Quality Threshold and Radio Quality Threshold. This option is disabled by default.
    Station Quality Threshold (1-50)Health index to track and assess the status of wireless client connections, from 1 to 50. A higher index value means the wireless station is connected with higher data rate and less packet drop.
    Wireless clients will be disconnected if station quality drops below the configured threshold.
    • Minimum value = 1
    • Maximum value = 50
    • Default value = 20
    Radio Quality Threshold (1-50)Health index to track and assess the status of radio band utilization, which varies between 1 and 50. A higher index value means radio band utilization is lower with less packet drop.
    The radio transmit power will be lowered if the radio quality drops below the configured threshold.
    • Minimum value = 1
    • Maximum value = 50
    • Default value = 20
    Dynamic Channel Selection Mode
    DCS Mode: Global / Local
    DCS Mode supports two settings for automatic channel selection:
    • Global Mode – Firewall assigns proper channel for all SonicWaves according to information received from all SonicWaves.
    • Local Mode – SonicWave finds the best channel according to the information from itself.
    Auto Channel Enable:
    2.4GHz Radio DCS Scheme
    5GHz Radio DCS Scheme
    2.4GHz or 5GHz Radio DCS Scheme options are:
    • Safe Mode (CGI value 0)
    SonicWaves switch to a better channel only without clients connected. This is conservative mode.
    • Steady Mode (CGI value 1)
    SonicWaves seek a better channel periodically in the background. This is moderate mode.
    • Swift Mode (CGI value 2)
    SonicWaves switch to a better channel as soon as noise/interference becomes high on the current channel. This is aggressive mode.
    Safe Mode is the default.
