Quality of Service

on the left window and click

submenu, or click the

QoS or Quality of Service allows your Router to help prioritize the data
packet flow in your Router and network. This is very important for time
sensitive applications such as VoIP where it may help prevent dropped
calls. Large amounts of non-critical data can be scaled so as not to
affect these prioritized sensitive real-time programs.
Tick the
Enable QoS
check box and select a default DSCP mark from
the drop-down menu.
When you are finished, click
Apply/Save
to take the settings effect.
