Configuring Wi-Fi Multimedia
Wi-Fi Multimedia (WMM), also referred to as Wireless Multimedia, is a subset of the 802.11e
standard. WMM allows wireless traffic to have a range of priorities, depending on the kind of data.
Time-dependent information, like video, audio, or voice will have a higher priority than normal
traffic.With WMM you can configure quality of service (QoS) to prioritize multimedia traffic in
four access categories: voice, video, best effort, and background. For WMM to function correctly,
wireless clients must also support WMM.
To configure WMM:
1. Log in to the gateway using its default address of http://192.168.0.1 or at whatever IP address
the unit is currently configured. Use the default user name of admin and default password of
password, or the password you have set up.
2. In the main menu, under Setup, select Wi-Fi Multimedea. The Wi-Fi Multimedia (WMM)
screen displays.
3. Configure the following WMM settings:
• WMM Support. Select the WMM mode:
– On. WMM is enabled
– Off. WMM is disabled.
• No-Acknowledgement. When the wireless communication quality is good, you do not
need an acknowledgement message (ACK) to confirm the reception of a packet. Disabling
acknowledgement messages might improve the efficiency of packet transmission. When
the wireless communication quality is poor, enable acknowledgement messages so that
you are notified when a package is lost.
– On. Acknowledgement messages are enabled.
