How do I configure wireless QoS in my SBG6580 Gateway?

WiFi Multimedia is an advanced feature that allows the SBG6580 to prioritize various types of data traveling over the wireless network.  Certain types of data that are sensitive to delays, such as voice or video, must be prioritized ahead of others, less delay-sensitive types, such as email.

WiFi Multimedia currently implements wireless Quality of Service (QoS) by transmitting data depending on the priority settings.  These priority are mapped into four Access Categories, in increasing order of priority:

  • Best Effort (AC_BE)
  • Background (AC_BK)
  • Video (AC_VI)
  • Voice (AC_VO)

The SBG6580 requires WiFi Multimedia (WMM)-capable clients, usually a separate feature enabled at the client network settings, and the client PC software that makes use of Differentiated Services (Diffserv). Refer to the operating system instructions for enabling QoS. This document describes how to enable and configure WMM in the SBG6580.

To Enable WiFi Multimedia (QoS)

  1. Launch a web browser, such as Internet Explorer, Firefox, or Safari.  Enter into the address box. The Login page appears.

    NOTE: By default the LAN IP address is  If the default address has been changed, enter the custom address in the address box.
  2. On the Login page:
    a.   Enter admin in the Username field.
    b.   Enter motorola in the Password field.
    c.   Click the Login button.  The Home page appears.

    NOTE: On firmware version and later, the default admin password is required to be changed.  The Change User Password prompt will immediately appear after logging into the Web manager with the default admin password.  For assistance with the Change User Password screen, please refer to article # 18055 - SBG6580 (v.8.9.x): Prompt to Change Default Admin Login.

  3. Move the mouse-cursor over the Wireless tab and select the Quality of Service sub-link.  The Wireless - Quailty of Service page appears.
    CAUTION: It is not recommended that these settings be modified without direct knowledge or instructions to do so.  Modifying these settings inappropriately could seriously degrade network performance.
  4. On the Wireless - Quality of Service page:
    a.   WMM Support - Set WMM support to On, or Off.
    b.   No-Acknowledgement - Set No-Acknowledgement to On or Off.  When enabled, acknowledgement for data are not transmitted.
    c.   Power Save Support - Set Power Save support to On or Off.  When Power Save is enabled, the Access Point (AP) queues packets for STAs that are in Power Save mode.  Queued packets are transmitted when the station (STA) notifies AP that it has left the Power-Safe mode.
    d.  Click the Apply button.
    NOTE: Transmit Parameters include Contention Window (CWmin and CWmax), Arbitration Inter Frame Spacing Number (AIFSN), and Transmit Opportunity Limit (TXOP Limit).
  5. EDCA AP Parameters - Specifies the transit parameters for traffic transmitted from the AP to STA.
    NOTE: Admission Control specifies if admission control is enforced for the Access Categories. Discard Oldest First specifies the discard policy for the queues.
  6. EDCA STA Parameters - Specifies the transit parameters for traffic transmitted from the STA to AP.
  7. EDCA TXOP Parameters - Specifies the transit parameters for traffic tranmitted from TXOP. 
  8. Click the Apply button.
