Configuring Quality of Service (QoS)

After you configure the bandwidth utilization settings, you must click Apply to apply 
the changes and to save the settings. Changing some settings might cause the 
access point to stop and restart system processes. If this happens, wireless clients 
will temporarily lose connectivity. We recommend that you change access point 
settings when WLAN traffic is low. 

Quality of Service (QoS) provides you with the ability to specify parameters on 
multiple queues for increased throughput and better performance of differentiated 
wireless traffic like 

Voice-over-IP (VoIP), other types of audio, video, and 

streaming media, as well as traditional IP data over the access point.

Configuring QoS on the access point consists of setting parameters on existing 
queues for different types of wireless traffic, and effectively specifying minimum 
and maximum wait times (through 

Contention Windows) for transmission. The 

settings described here apply to data transmission behavior on the access point 
only, not to that of the client stations.

AP Enhanced Distributed Channel Access (EDCA) Parameters affect 
traffic flowing from the access point to the client station.

Station Enhanced Distributed Channel Access (EDCA) Parameters 
affect traffic flowing from the client station to the access point.

The default values for the access point and station EDCA parameters are those 
suggested by the Wi-Fi Alliance in the WMM specification. In normal use these 
values should not need to be changed. Changing these values will affect the QoS 
provided.

To set up queues for QoS, click the QoS tab under the Services heading and 
configure settings as described in 

.
