Enable/Disable Wi-Fi Multimedia
By default, Wi-Fi MultiMedia (WMM) is enabled on the access point. With WMM enabled, QoS settings on
the Professional Access Point control both downstream traffic flowing from the access point to client
station (access point EDCA parameters) and upstream traffic flowing from the station to the access point
(station EDCA parameters). Enabling WMM essentially activates station-to-access-point QoS control.
Disabling WMM will deactivates QoS control of "station EDCA parameters" on upstream traffic flowing from

Get QoS Settings on the Access Point get tx-queue
Get QoS Settings on the Client Station get wme-queue
Set Arbirtation Interframe Spaces (AIFS) On the access point:
set wme-queue wlan0 with queue Queue_Name to
aifs AIFS_Value
On a client station:
set wme-queue wlan0 with queue Queue_Name to
aifs AIFS_Value
See examples in “Set Arbirtation Interframe Spaces (AIFS)” on
page 241
Setting Minimum and Maximum Conten-
tion Windows (cwmin, cwmax) On the access point:
set tx-queue wlan0 with queue Queue_Name to
cwmin cwmin_Value cwmax cwmax_Value
On a client station:
set wme-queue wlan0 with queue Queue_Name to
cwmin cwmin_Value cwmax cwmax_Value
See examples in “Setting Minimum and Maximum Contention Win-
dows (cwmin, cwmax)” on page 242 .
Set the Maximum Burst Length (burst) on
the Access Point set tx-queue wlan0 with queue Queue_Name to
burst burst_Value
See examples in “Set the Maximum Burst Length (burst) on the
Access Point” on page 243 .
Set Transmission Opportunity Limit (txop-
limit) for WMM client stations set wme-queue wlan0 with queue Queue_Name to
txop-limit txop-limit_Value
See examples in “Set Transmission Opportunity Limit (txop-limit) for
WMM client stations” on page 244 .
