WLAN QoS Support 
The WLAN QoS is supported; however, it is hard-coded and is not configurable on the Ingress 
and Egress pages.

There is no shaper support on WLAN interface. 
Shaper 
The shaper provides a way of determining priorities of different traffic classes. Three shaper 
algorithms are supported: HTB (hierarchical token bucket), Low Latency Queue Discipline, and 
PRIOWRR (priority based round robin). 
 
HTB  
Shapes the traffic of a class over the specific interface. All CoSx (where x= 1 to 6) is 
assigned a specific rate that data will be shaped to meet; for example, if CoS1 is 
100Kbps even 300Kbps of data is received on the interface only 100Kbps will be 
sent. Of the Max Rate entered rates for each CoS channel may be configured. If 
Max Rate is 300Kbps, Cos1 is configured for 100Kbps, CoS2 and CoS3 are 
configured for 150Kbps each and CoS6 for 300Kbps. CoS6 can use the whole 
300Kbps of bandwidth only when there are no CoS1, CoS2, or CoS3 packets. 
Low Latency  
CoS1 is not rate limited, so the CoS1 field is disable when Low Latency Queue 
Discipline
 is checked. CoS1 takes priority (much as if CoS1 was set to Max Rate) If
