The QoS screen allows you to automatically give a service (such as VoIP and video) a priority level.

Click Network > Wireless LAN 2.4G or 5G > QoS. The following screen appears.

Figure 21   Network > Wireless LAN 2.4G or 5G > QoS 

The following table describes the labels in this screen. 

Fragmentation 
Threshold

The threshold (number of bytes) for the fragmentation boundary for directed messages. It is the 
maximum data fragment size that can be sent. 

Note: If you select 802.11n, 802.11gn or 802.11bgn in the Wireless LAN 2.4G or 5G> 

General screen, this field is not configurable and the WAP7205 automatically 
changes to use the maximum value.

Intra-BSS Traffic 
blocking

A Basic Service Set (BSS) exists when all communications between wireless clients or between a 
wireless client and a wired network client go through one access point (AP). 

Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS traffic is enabled, 
wireless clients can access the wired network and communicate with each other. When Intra-
BSS traffic is disabled, wireless clients can still access the wired network but cannot 
communicate with each other.

Select Enable to prevent crossover traffic from within the same SSID on the WAP7205.

Short Guard 
Interval

Select Enable to use Short GI (Guard Interval). 

The guard interval is the gap introduced between data transmission from users in order to 
reduce interference. Reducing the interval increases data transfer rates but also increases 
interference. Increasing the interval reduces data transfer rates but also reduces interference.

Tx Power

Set the output power of the WAP7205 in this field. If there is a high density of APs in an area, 
decrease the output power of the WAP7205 to reduce interference with other APs. Select one 
of the following 100%, 90%, 75%, 50%, 25% or 10%. 

Apply

Click Apply to save your changes back to the WAP7205.

WMM QoS

Select Enable to have the WAP7205 automatically give a service a priority level 
according to the ToS value in the IP header of packets it sends. WMM QoS (Wifi 
MultiMedia Quality of Service) gives high priority to voice and video, which makes them 
run more smoothly.
