Wireless Multi-media (WMM) Settings
Router EDCA Parameters (Enhanced Distributed Channel Access) govern wireless data from your
Gateway to the client;
Client EDCA Parameters govern wireless data from the client to your Gateway.
set wireless wmm option [ off | on ]
Enables or disables wireless multi-media settings option, which allows you to fine tune WiFi Multimedia
Quality of Ser vice (QoS) by transmitting data depending on Diffser v priority settings. These priorities
are mapped into four Access Categories (AC), in increasing order of priority: Background (BK), Best
Effor t (BE), Video (VI), and Voice (VO). It requires WiFi Multimedia-capable clients, usually a separate
feature enabled at the client.
❑ aifs: (Arbitration Interframe Spacing) the wait time in milliseconds for data frames.
Valid values are: 1 – 255
❑ cwmin: (Minimum Contention Window) upper limit in milliseconds of the range for determining initial
random backoff. The value you choose must be lower than cwmax.
Valid values are: 1, 3, 7, 15, 31, 63, 127, 255, or 511.
❑ cwmax: (Maximum Contention Window) upper limit in milliseconds of the range of determining final
random backoff. The value you choose must be higher than cwmin.
Valid values are: 3, 7, 15, 31, 63, 127, 255, 511, or 1023.
❑ txoplimit: Time interval in microseconds that clients may initiate transmissions.
Valid values are: 0 – 9999.

NOTE:
It is not recommended that you modify these settings without direct knowledge or instruc-
tions to do so. Modifying these settings inappropriately could seriously degrade network
per formance.
